MLS/Aura Level 2 Temperature V005 (ML2T)

ML2T is the EOS Aura Microwave Limb Sounder (MLS) standard product for temperature derived from radiances measured by the 118 and 240 GHz radiometers. 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 recommended useful vertical range is from 261 to 0.001 hPa, and the vertical resolution is between 3 and 6 km. Users of the ML2T data product should read section 3.22 of 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 two swath objects (profile and column data), each with a set of data and geolocation fields, swath attributes, and metadata.
