As part of the SORTIE project a new data processor has been developed to improve retrievals of water leaving radiance from in situ radiometry. The processor produces water leaving radiances from classical single cast profiles, surface float casts, and a new multicast technique. The processor takes into consideration new characterization methods used on hyperspectral radiometers including stray light correction using data collected at the NIST SIRCUS facility and thermal responsivity corrections. The processor has a number of features to improve water leaving radiance calculations including normalization of profiles for incident irradiance, statistics on regressed parameters (Klu, Ked, Ed(0-), Lu(0-)), in addition to graphical and numeric data quality checks. The data output has also been significantly improved to include SeaBASS compliant output. The new processor has been validated against the JRC SeaProc data processor and is expected to significantly improve water leaving radiance retrievals, particularly in more challenging coastal environments.
