Description

ML2EDMPGEOS5294 is the EOS Aura Microwave Limb Sounder (MLS) product with derived meteorological variables from GEOS-IT 5.29.4 at the MLS profile locations. The data version is 5.0. Spatial coverage is near-global (-82 degrees to +82 degrees latitude), with each profile spaced 1.5 degrees or ~165 km along the orbit track (roughly 15 orbits per day). The vertical range is from 1000 to 0.01 hPa, and the vertical resolution is between 3 and 6 km. Users of the ML2EDMPGEOS5294 data product should read the EOS MLS Level 2 Version 5 Quality Document for more information.

The data are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5), which is based on the version 5 Hierarchical Data Format, or HDF-5. Each file contains several swath objects for a meteorological variable, each with a set of data and geolocation fields, swath attributes, and metadata.
