By incorporating the domain knowledge into a machine learning model, KGML-ag overcomes the well-known limitations of process-based models due to insufficient representations and constraints, and unlocks the “black box” of machine learning models. Therefore, KGML-ag can outperform existing approaches on capturing the hot moment and complex dynamics of N2O flux. This study will be a critical reference for the new generation of modeling paradigm for biogeochemistry and other geoscience processes.

Seventy percent of global CO2 emissions were emitted from urban landscapes. The Yangtze River delta (YRD) ranks as one of the most densely populated regions in the world and is an anthropogenic CO2 hotspot. Besides anthropogenic factors, natural ecosystems and croplands act as significant CO2 sinks and sources. Independent quantification of the fossil and cement CO2 emission and assessment of their impact on atmospheric δ13C-CO2 have potential to improve our understanding of urban CO2 cycling.

Methane concentrations have doubled since 1750. The US Upper Midwest is a key region contributing to such trends, but sources are poorly understood. We collected and analyzed aircraft data to resolve spatial and timing biases in wetland and livestock emission estimates and uncover errors in inventory treatment of manure management. We highlight the importance of intensive agriculture for the regional and US methane budgets and the potential for methane mitigation through improved management.

This paper uses three different frameworks to derive nitrous oxide (N2O) emissions based on global surface observations. One of these frameworks employs a new approach that allows for fast computation and explores a larger solution space than other methods. Our results point to a few conclusions about the global N2O budget, including a larger contribution from tropical sources, an overestimate of natural soil emissions, and an underestimate of agricultural sources particularly in springtime.

To the best of our knowledge, no modeling studies have been published on the relationship between the spatial characteristics of agricultural N2O emissions and the atmospheric N2O mixing ratio at the regional scale. To fill this gap, we proposed a simple inverse analysis method based on tower measurements and an Eulerian model. According to our study, the N2O emissions from the U. S. Corn Belt is clearly estimated by IPCC, and such underestimate is not dependent on tower measurement location.

This paper introduces a new inversion framework for N2O using GEOS-Chem and its adjoint, which we employed in a series of observing system simulation experiments to evaluate the source and sink constraints provided by surface and aircraft-based N2O measurements. We also applied a new approach for estimating a posteriori uncertainty for high-dimensional inversions, and used it to quantify the spatial and temporal resolution of N2O emission constraints achieved with the current observing network.

Water molecules stick to air intake tubing wall surfaces and exchange with ambient vapor. This can slow signal change measurements. We tested whether material type affects this stickiness. Less stickiness would lead to an instrument seeing signal changes faster. We unexpectedly saw no difference in signal speed between material types. Water vapor stable isotope users can more confidently use plastic tubing and compare measurements across observation systems that used different tubing materials.

We present results of a hydrologic study of groundwater recharge near the city of Arequipa, Peru. There are a number of springs below a high-elevation salar that show some chemical evidence of connectivity to the salar basin, possibly facilitated by faults in region. These results suggest that this salar basin is not a strictly terminal lake but that some interbasin groundwater flow exists. In addition, a high-elevation forest ecosystem seems important for groundwater recharge as well.

Previous studies showed that black carbon (BC) could warm the surface with decreased incoming radiation. With climate models, we found that the surface energy redistribution plays a more crucial role in surface temperature compared with other forcing agents. Though BC could reduce the surface heating, the energy dissipates less efficiently, which is manifested by reduced convective and evaporative cooling, thereby warming the surface.

Inland lakes play an important role in regulating local climate. In this paper, we describe a dataset on microclimate and eddy covariance variables measured at a network of sites across Lake Taihu. The dataset, which appears to be the first of its kind for lake systems, can be used for validation of lake–air flux parameterizations, investigation of climatic controls on lake evaporation, evaluation of remote-sensing surface data products and global synthesis on lake–air interactions.

We conducted airborne vertical profile measurements of water vapor stable isotopes to examine how boundary layer, cloud, and mixing processes influence the vertical structure of deuterium excess in the lower troposphere. We discuss reasons our observations are consistent with water vapor isotope theory on some days and not others. Deuterium excess may be useful for understanding complex processes occurring at the top of the boundary layer, including cloud formation, evaporation, and air mixing.

Although a total ban on straw burning has been enforced in eastern China, the regionally transported biomass burning emissions remarkably impacted the chemical and optical properties of carbonaceous aerosols in Nanjing, which were quantified by a calculation based on measured data and a simulation based on a model. Results showed that regionally transported biomass burning emissions significantly contributed to the carbonaceous aerosols and impacted the solar radiation balance of the atmosphere.

Deforestation not only releases carbon dioxide to the atmosphere but also affects local climatic conditions by altering energy fluxes at the land surface and thereby the local temperature. Here, we evaluate the local impact of deforestation in a widely used land surface model. We find that the model reproduces the daytime warming effect of deforestation well. On the other hand, the warmer temperatures observed during night in forests are not present in this model.

This paper evaluates the performance of two commonly used land surface models in simulating deforestation-induced change in surface fluxes using paired FLUXNET observations. Our results highlight the shortcomings in the energy partitioning between latent and sensible heat flux over different land cover types, suggesting the need to improve the representation of surface heat flux processes in land models to increase confidence in LULCC-climate simulations.

Heat stress associated with climate change is one of most severe threats to human society. The problem is further compounded in urban areas by urban heat islands (UHIs). We use an urban climate model to evaluate the cooling benefits of active urban heat mitigation strategies both individually and collectively. We show that by forming UHI mitigation wedges, these strategies have the potential to significantly reduce the UHI effect plus warming induced by greenhouse gases.

The Yangtze River Delta is one of the most industrialized regions in China. In situ optical isotopic measurement in Nanjing, a city located in the Delta, showed unusually high atmospheric δ13C signals in the summer (−7.44 ‰, July 2013 mean), which we attributed to the influence of cement production in the region. Flux partitioning calculations revealed that natural ecosystems in the region were a negligibly small source of atmospheric CO2.

Boreal and arctic ecosystems have been responding to elevated temperatures and atmospheric CO2 over the last decades. It is not clear if these ecosystems are sequestering more carbon or possibly becoming sources. This is an important feedback of the carbon cycle to global warming. We studied monthly biological land CO2 fluxes inferred from atmospheric CO2 concentrations using inverse models and found that net summer CO2 uptake increased, resulting in a small increase in annual CO2 uptake.

To better understand the spatial and temporal distribution of vapor isotopes, we present two vehicle-based spatially continuous snapshots of the near-surface vapor isotopes in China during the pre-monsoon and monsoon periods. These observations are explained well by different moisture sources and processes along the air mass trajectories. Our results suggest that proxy records need to be interpreted in the context of regional systems and sources of moisture.

Evaluating methane (CH4) sources in the Athabasca oil sands region (AOSR) is crucial to effectively mitigate CH4 emissions. We tested the use of carbon isotopes to estimate source contributions from key CH4 sources in the AOSR and found that 56 ± 18 % of CH4 emissions originated from surface mining and processing facilities, 34 ± 18 % from tailings ponds, and 10 ± < 1 % from wetlands, confirming previous findings and showing that this method can be successfully used to partition CH4 sources.

To gain understanding on the vertical structure of atmospheric water vapour above mountain lakes and to assess its link to the isotopic composition of the lake water and small-scale dynamics, the L-WAIVE field campaign was conducted in the Annecy valley in the French Alps in June 2019. Based on a synergy between ground-based, boat-borne, and airborne measuring platforms, significant gradients of isotopic content have been revealed at the transitions to the lake and to the free troposphere.

This study introduces 2 years of continuous near-surface in situ observations of the stable isotopic composition of water vapour in parallel with precipitation in north-eastern Siberia. We evaluate the atmospheric transport of moisture towards the region of our observations with simulations constrained by meteorological reanalyses and use this information to interpret the temporal variations of the vapour isotopic composition from seasonal to synoptic timescales.

Stable water isotopes (SWIs) are tracers of moist atmospheric processes. We analyse the impact of large- to small-scale atmospheric processes and various environmental conditions on the variability of SWIs using ship-based SWI measurement in water vapour from the Atlantic and Southern Ocean. Furthermore, simultaneous measurements of SWIs at two altitudes are used to illustrate the potential of such measurements for future research to estimate sea spray evaporation and turbulent moisture fluxes.

We conducted airborne vertical profile measurements of water vapor stable isotopes to examine how boundary layer, cloud, and mixing processes influence the vertical structure of deuterium excess in the lower troposphere. We discuss reasons our observations are consistent with water vapor isotope theory on some days and not others. Deuterium excess may be useful for understanding complex processes occurring at the top of the boundary layer, including cloud formation, evaporation, and air mixing.

This article studies the interaction between falling rain and vapour with stable water isotopes. In particular, rain evaporation is relevant for several atmospheric processes, but remains difficult to quantify. A novel framework is introduced to facilitate the interpretation of stable water isotope observations in near-surface vapour and rain. The usefulness of this concept is demonstrated using observations at high time resolution from a cold front. Sensitivities are tested with a simple model.

Analysis of stable isotope composition of daily precipitation collected along the southern foothills of the Himalayas was used to gain deeper insight into the mechanisms controlling isotopic composition of precipitation. The results suggested that the decrease in isotopic composition in the course of ISM evolution stems from large-scale recycling of moisture-driven monsoonal circulation. High d-excess of rainfall is attributed to moisture of continental origin released into the atmosphere.

We report here the first survey of stable water isotope composition over the Mediterranean sea made from aircraft. The stable isotope composition of the atmospheric water vapour changed in response to evaporation conditions at the sea surface, elevation, and airmass transport history. Our data set will be valuable for testing how water is transported in weather prediction and climate models and for understanding processes in the Mediterranean water cycle.

Water vapor source and transport are linked to the stable isotopes of precipitation of 70 storms at Barrow, AK, USA. Barrow's vapor came from the North Pacific in winter and the Arctic Ocean in summer. Half the isotopic variability was explained by the size of the temperature drop from the vapor source to Barrow, the evaporation conditions, and whether the vapor traveled over mountains. Because isotopes reflect the regional meteorology they may be early indicators of Arctic hydroclimatic change.

The Yangtze River Delta is one of the most industrialized regions in China. In situ optical isotopic measurement in Nanjing, a city located in the Delta, showed unusually high atmospheric δ13C signals in the summer (−7.44 ‰, July 2013 mean), which we attributed to the influence of cement production in the region. Flux partitioning calculations revealed that natural ecosystems in the region were a negligibly small source of atmospheric CO2.

Post-depositional fractionation of stable water isotopes due to fractioning surface evaporation introduces uncertainty to isotope applications such as the reconstruction of paleotemperatures, paleoaltimetry, and the investigation of ground water formation. In this paper we combine measurements of stable water isotopes in near-surface water vapor with a Lagrangian isotope model to investigate isotope fractionation during the evaporation of surface-layer snow in central Europe.

Climatic conditions in Concordia are very cold (−55 °C in average) and very dry, imposing difficult conditions to measure the water vapour isotopic composition. New developments in infrared spectroscopy enable now the measurement of isotopic composition in water vapour traces (down to 20 ppmv). Here we present the results results of a first campaign of measurement of isotopic composition of water vapour in Concordia, the site where the 800 000 years long ice core was drilled.

Measurements of water vapour isotopologues, dust, and a back trajectory model were used to identify moisture pathways in the subtropical North Atlantic. Dry air masses, from condensation at low temperatures, are transported from high altitudes and latitudes. The humid sources are related to the mixture, with lower and more humid air during transport. Rain re-evaporation was an occasional source of moisture. In summer, an important humidity source is the strong dry convection over the Sahara.

Combining 14C and 13C data from the Los Angeles, CA megacity with background data allows source attribution of CO2 emissions among biosphere, natural gas, and gasoline. The 8-year record of CO2 emissions from fossil fuel burning is consistent with "The Great Recession" of 2008–2010. The long-term trend and source attribution are consistent with government inventories. Seasonal patterns agree with the high-resolution Hestia-LA emission data product, when seasonal wind directions are considered.

We investigated soil production and uptake of H2 and associated isotope effects. Uptake and emission of H2 occurred simultaneously at all sampling sites, with strongest emission where N2 fixing legume was present. The fractionation constant during soil uptake was about 0.945 and it did not show positive correlation with deposition velocity. The isotopic composition of H2 emitted from soil with legume was about -530‰, which is less deuterium-depleted than isotope equilibrium between H2O and H2.

Based on summer measurements of δ18O and δD in the atmospheric vapour of a Mediterranean coastal wetland exposed to high evaporation, this paper explores the main drivers of isotopic signal variability. After having classified the data according to the main regional air mass trajectories, average diurnal cycles are discussed with regards to the contribution of local evaporation to the ground level atmospheric vapour.

Short summary
Increasing atmospheric humidity and convective precipitation over land provide evidence of intensification of the hydrologic cycle. We present the first multi-annual isotope (oxygen and deuterium) water vapor observations from a very tall tower (185 m) in the upper Midwest, United States, to diagnose the sources, transport, and fractionation of water vapor in the atmosphere. The results show a relatively high degree of summertime water recycling within the region (~30 % mean and ~60 % maximum).
