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

CALIPSO Infrared Imaging Radiometer (IIR) Level 2 Track, V4-20 NASA

Short summary
The IIR Level 2 data products include cloud effective emissivities and cloud microphysical properties such as effective diameter (De) 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).
