MLS/Aura Level 3 Hydroperoxy (HO2) Daily 10degrees Lat Zonal Mean V004 (ML3DZMHO2) at GES DISC

Metadata Updated: December 6, 2023

ML3DZMHO2 is the EOS Aura Microwave Limb Sounder (MLS) daily zonal mean product for hydroperoxy derived from radiances measured in two bands from the 640 GHz radiometer. The data version is 4.2. Data coverage is from August 2, 2004 to current. Spatial coverage is near-global (-85 degrees to 85 degrees latitude) spaced every 10 degrees in latitude. The recommended useful vertical range is between 21.5 to 0.0464 hPa, and the vertical resolution is about 5 km. Users of the ML3DZMHO2 data product should read the MLS Radiance Average Retrievals (RAR) Product Guideline document, as well as section 3.2 of the EOS MLS Level 2 Version 4 Quality Document for more information.

The data are stored in the version 4 network Common Data Form (netCDF4), which is built on the version 5 Hierarchical Data Format, or HDF5. The netCDF4 files follow the Climate and Forecast (CF) metadata conventions. Each file contains two zonal means objects or groups, one with data from the daytime part of the MLS orbit, the other with the nighttime data. Each zonal means object contains the average, error (precision), solar zenith angle, and local solar time for each latitude band and pressure level. Files also contain metadata attributes describing the data and product.
