Version 4 CALIPSO Imaging Infrared Radiometer ice and liquid water cloud microphysical properties – Part I: The retrieval algorithms

Anne Garnier, Jacques Pelon, Nicolas Pascal, Mark A. Vaughan, Philippe Dubuisson, Ping Yang, and David L. Mitchell

Data sets

CALIPSO Imaging Infrared Radiometer (IIR) Level 2 Track data, Beta V3-01 NASA https://doi.org/10.5067/IIR/CALIPSO/L2_Track-Beta-V3-01

CALIPSO Infrared Imaging Radiometer (IIR) Level 2 Track, V4-20 NASA https://doi.org/10.5067/CALIOP/CALIPSO/CAL_IIR_L2_Track-Standard-V4-20

Short summary

The IIR Level 2 data products include cloud effective emissivities and cloud microphysical properties such as effective diameter (D_e) and ice or liquid water path estimates. This paper (Part I) describes the improvements in the V4 algorithms compared to those used in the version 3 (V3) release, while results are presented in a companion paper (Part II).
