Abstract. The outgoing long-wave radiation from the Earth's atmosphere in the
far infrared spectral region is mostly unexplored, while is well
recognized that the water vapour contribution to greenhouse trapping
is dominant in this region. The Radiation Explorer in the Far
InfraRed (REFIR) study has proven the feasibility of a space-borne
Fourier transform spectrometer able to perform the measurement in
the 100–1100 cm−1 range with a resolution of 0.5 cm−1.
Following this work a prototype of the spectrometer named REFIR-PAD
(Prototype for Applications and Development) has been developed to
observe the atmospheric radiance from both ground-based sites and
from stratospheric balloon platforms. In this work we describe the
REFIR-PAD level 1 data analysis procedure, that, starting from raw
instrumental data produces the calibrated atmospheric spectral
radiance. Performances of the procedure are also described.
