MLS/Aura Level 3 Daily Binned Cloud Ice (IWC) on Assorted Grids V005 (ML3DBIWC) at GES DISC

Published by NASA/GSFC/SED/ESD/TISL/GESDISC | National Aeronautics and Space Administration | Catalog Last Checked: May 26, 2026 at 05:54 PM | Dataset Last Updated: May 18, 2026
ML3DBIWC is the EOS Aura Microwave Limb Sounder (MLS) daily binned on various vertical grids product for cloud ice water content (IWC) derived from radiances measured by the 240 GHz radiometer. The data version is 5.1. Spatial coverage is near-global (-82 to +82 degrees latitude) at a spatial resolution of 4 degrees latitude by 5 degrees longitude. The recommended useful vertical range is from 215 to 82.5 hPa, and the vertical resolution is about 3 km. Users of the ML3DBIWC data product should read chapter 4 and sections 3.15 and 3.16 of the EOS MLS Level 2 Version 5 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 six group objects: lat-lon map vs pressure, lat vs pressure zonal mean, lat-lon map vs "potential temperature", lat vs "potential temperature" zonal mean, "equivalent latitude" vs "potential temperature" zonal mean, and vortex average vs "potential temperature". Each group has a set of data (average, min, max, std dev, rms) and geolocation fields, grid attributes, and metadata.
