Water vapour DiAL LEANDRE 2 - version 2

The water vapour differential absorption lidar (DiAL) LEANDRE 2 was flown onboard the SAFIRE ATR 42 during the HYMEX SOP 1. It was available from 11-Sep-2012 to 26-Nov-2012 for 22 flights. LEANDRE 2 provides atmospheric water vapour mixing ratio profiles and the associated error profiles with a vertical resolution of 150 m and a horizontal resolution of roughly 1 km. Water vapour mixing ratio profiles are gridded to 25 m. Each data file (provided as netCDF) corresponds to a so-called leg for a given flight. The length of the legs is a function of the complexity of the flight track, and is highly variable from one flight to the next.Also see the LEANDRE 2 QL catalogue available from: http://sop.hymex.org/archive//observation/ohayon/ATR/L2_Catalogue.pdf
