Summary

Abstract: ML2DGG is the EOS Aura Microwave Limb Sounder (MLS) product containing geophysical diagnostic quantities pertaining directly to the standard geophysical data products, generally on a similar (or identical) grid, and at different spectral ranges. The current version is 2.2. Data coverage is complete from August 8, 2004 to current. Spatial coverage is near-global (-82¬∞ to +82¬∞ latitude), with each profile spaced 1.5¬∞ or ~165 km along the orbit track (roughly 15 orbits per day). Vertical resolution varies between species and typically ranges from 3 - 6 km. Users of the ML2DGG data product should read the Supplement to Version 1.5 Level 2 Data Quality and Description Document for more information (http://mls.jpl.nasa.gov/data/v1-5-supplement-29jul05b.pdf).

Users are encouraged to register with the MLS science team at https://mls.jpl.nasa.gov/forms/reguser.php to obtain updates and information about this data product.

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 HDF5. Each file contain swaths objects for each diagnostics measurement. Each swath has a set of data and geolocation fields, swath attributes, and metadata. The data fields include the geophysical parameter values and precision (standard deviation), convergence values, data quality, and a status flag. The geolocation fields include a time stamp in TAI-93 format (seconds since January 1, 1993), geodetic latitude and longitude, and pressure level values, as well as local solar time, solar zenith angle, line of sight angle, and orbit geodetic angle. There is one file per day.
