Products

There are three types of Level 2 data products:

  • Archival
  • Standard
  • Summary

TROPESS-MUSES Level 2 data are in netcdf format and contain retrieved trace gas species (or temperature) profiles at the observation targets. Level 2 data are generated using legacy TES data processing algorithms and L1B inputs from either a single instrument (e.g., AIRS, CrIS) or combinations of multiple instruments (e.g. AIRS-OMI). Data products also include geolocation information, estimated errors, quality flags and other information needed for science and applications end uses.

Processing Streams: Forward Stream (FS), Reanalysis Stream (RS), and Special Collections (SC).

Level 2 Product Types and File Size Estimates
Product Level Product Name Granularity Description File Size Estimate (approximate size per file, per day; actual size will vary depending on gas species)
L2 = Level 2 Full archival Daily Full, archival version of the L2 product, with daily granularity. Contains all variables required for science analysis ~10 GB
Standard Daily Standard data product, with daily granularity. “Lite” product that contains a limited set of variables needed for science analysis. ~100 MB
Summary Daily Summary data product, with daily granularity. Contains a limited set of variables needed for science analysis. ~10 MB

*Note: Surface Temperature (T_SURF) is included in the species product files, not as a separate file so it is not included in this table.
**H2O (water vapor) product was to be contained within the HDO product.

File Format and Structure

The files in these collections are in NetCDF-4 format. NetCDF is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data that was developed by UCAR/Unidata (http://doi.org/10.5065/D6H70CW6) https://www.unidata.ucar.edu/software/netcdf/.

Special Collections

Products that are typically made available through the DAAC include:

  • West Coast Fires 2020
  • CrIS CO dataset (Buchholz et al., 2020)
  • Australian Fires 2019-2020
