Summary

Description

ML2O3_NRT is the EOS Aura Microwave Limb Sounder (MLS) Near-Real-Time (NRT) product for ozone (O3). This product contains daily O3 profiles taken from the 240 GHz band. The most recent 7 days of data are available. 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 range of NRT Ozone profiles is 261 - 0.0215 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 3.4 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 O3 data.
