MLS/Aura Level 2 Methanol (CH3OH) Mixing Ratio V004 (ML2CH3OH) at GES DISC

Description

At this time it is recommended that these data not be used pending further validation.ML2CH3OH is the EOS Aura Microwave Limb Sounder (MLS) standard product for methanol derived from radiances measured by the 640 GHz radiometer. The data version is 4.2. Data coverage is from August 8, 2004 to current. Spatial coverage is near-global (-82 degrees to +82 degrees latitude), with each profile spaced 1.5 degrees or ~165 km along the orbit track (roughly 15 orbits per day). The recommended useful vertical range is between 147 and 100 hPa, and the vertical resolution range is about 4-5 km. Users of the ML2CH3OH data product should read section 3.5 of the EOS MLS Level 2 Version 4 Quality Document for more information. The data are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5), which is based on the version 5 Hierarchical Data Format, or HDF-5. Each file contains one swath object (profile data), with a set of data and geolocation fields, swath attributes, and metadata.
