ML2CO_NRT is the EOS Aura Microwave Limb Sounder (MLS) Near-Real-Time (NRT) product for water vapor (H2O). This product contains daily H2O profiles taken from the 190 GHz band. The most recent 7 days of data are available. Spatial coverage is near-global (-82° to +82° latitude), with each profile spaced 1.5° or ~165 km along the orbit track (roughly 15 orbits per day). The recommended useful vertical range of NRT Water Vapor profiles is 316 - 0.00215 hPa. There are about 96 NRT files per day containing roughly 15 minutes or less of data each.
Before using these data, please download both the MLS version 3.3 NRT User Guide which describes the NRT algorithm and data quality, as well as the MLS Level-2 Data Quality Document for Standard Products which describes the caveats for using MLS H2O data. MLS documentation can be found at http://disc.sci.gsfc.nasa.gov/Aura/additional/documentation/.

The MLS NRT data are not as accurate as the retrievals that constitute the standard MLS products, but nevertheless the results are of scientific use and track the standard MLS products with reasonable fidelity. NRT water vapor profiles are only recommended for scientific use at pressure levels from 316 hPa to 0.00215 hPa.
