all edu.ucar.gdex SATELLITE NetCDF Freely Available This global dataset contains a climatology of 12 monthly averages and standard deviations of tropospheric column ozone from the Ozone Monitoring Instrument/Microwave Limb Sounder (OMI/MLS) on NASA's Aura satellite. We provide data for definitions of the troposphere truncated at 300 hPa and 100 hPa pressure levels. Data are sampled from January 2005-December 2024. These data are compiled for usage on the NSF NCAR ADF model evaluation and diagnostics package (https://github.com/NCAR/ADF). The dataset is truncated to 75.5S to 75.5N because of some ozone misrepresentation and retrieval difficulty near the poles. Spatial resolution: 1 longitude x 1 latitude global, truncated to 75.5S to 75.5N UCAR/NCAR/ACOM NCAR/GDEX 2.639 2025-07-30T20:45:19.183Z 2.639 2025-07-30T20:45:19.535Z 2.639 2025-07-30T20:45:19.752Z 2.639 2025-07-30T20:45:20.485Z
