Validation of remotely sensed profiles of atmospheric state variables: strategies and terminology T. von Clarmann Forschungszentrum Karlsruhe, Institut für Meteorologie und Klimaforschung, Karlsruhe, Germany
Abstract. This paper summarizes and classifies the
various approaches to validation of remote measurements
of atmospheric state variables, and tries to recommend a
clear and unambiguous terminology. The following approaches
have been identified: Intercomparison of individual profiles for
accuracy validation; statistical comparison of matched pairs
of measurements with respect to bias determination and precision
validation; statistical intercomparison of randomly sampled
measurements by two instruments, and comparison of a single
measurement to an ensemble of measurements. Applicable statistics
are shortly reviewed, and recipes for evaluation of the
co-incidence error due to less than perfect co-incidences are presented.
An approach is suggested to quantitatively validate profile
measurements when full covariance matrices are unavailable.
