Description

ML3MBCO is the EOS Aura Microwave Limb Sounder (MLS) monthly binned on various vertical grids product for carbon monoxide (CO) derived from radiances measured by the 640 GHz radiometer. The data version is 5.1. Data coverage is from August 2005 to current. 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 between 215 and 0.00464 hPa, and the vertical resolution is about 6 km. Users of the ML3MBCO data product should read chapter 4 and section 3.7 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 two grid objects (profile and column data), each with a set of data and geolocation fields, grid attributes, and metadata.
