MLS/Aura Level 2 Relative Humidity With Respect To Ice V002 (ML2RHI) at GES DISC

[ Get Data ]

Abstract: ML2RHI is the EOS Aura Microwave Limb Sounder (MLS) standard product for relative humidity with respect to ice derived from radiances measured by the 118 and 190 GHz radiometers. The current version is 2.3. Spatial coverage is near-global (-82 deg. to +82 deg. latitude), with each profile spaced 1.5 deg. or ~165 km along the orbit track (roughly 15 orbits per day). The recommended useful vertical ... View entire text
