MLS/Aura Level 3 Monthly Binned Ozone (O3) Mixing Ratio on Assorted Grids V004 (ML3MBO3)

Published by NASA/GSFC/SED/ESD/TISL/GESDISC | National Aeronautics and Space Administration | Catalog Last Checked: September 08, 2026 at 11:22 PM | Dataset Last Updated: September 08, 2026
ML3MBO3 is the EOS Aura Microwave Limb Sounder (MLS) monthly binned on various vertical grids product for ozone (O3) derived from radiances measured by the 240 GHz radiometer. The data version is 4.2. Spatial coverage is near-global (-82 to +82 degrees latitude), with a spatial resolution of 4 degrees latitude by 5 degrees longitude. The recommended useful vertical range is from 261 to 0.0215 hPa, and the vertical resolution is between 2.5 and 6 km. Users of the ML3MBO3 data product should read chapter 4 and section 3.18 of the EOS MLS Level 2 Version 4 Quality Document for more information. The data files are archived in the netCDF4 format, which is also compatible with HDF5 readers and tools. Each file contains two grid objects (profile and column data), each with a set of data and geolocation fields, grid attributes, and metadata.
