Vertical profiles of ozone, nitrogen dioxide (NO2), and water vapor (H2O) concentrations as well as multi-wavelength aerosol extinction coefficient are included in the solar Level 2 data product files. Three ozone profiles are available in this release of the solar products: a UVbased mesospheric product (i.e., “Ozone_Mes” in the product files) and two Chappuis-based products. One Chappius-based product uses a spectrally-focused spectral fitting retrieval (i.e., “Ozone_MLR”) while the other uses a broad-spectrum retrieval scheme that is similar to that of SAGE II (i.e., “Ozone_AO3”). Composite ozone and retrieved temperature/pressure products are not included in the V5.21 data set. Vertical profiles of ozone, nitrogen dioxide (NO2), and nitrogen trioxide (NO3) concentrations are included in the lunar Level 2 product files. Chlorine Dioxide (OClO) from lunar occultation are not included in this release. The channel wavelengths used in solar and lunar retrievals are available in the Data Product User’s Guide (DPUG).
Both IDL and Python reader software are available to access the products in the native format. New readers are required for this release. The product formats have changed slightly, so new readers are being provided. Readers for previous versions of SAGE III data are not compatible with this version. However, the new version of the IDL and Python data readers are backwards compatible with the previous version of the data product. Note that Version 5.21 product files in HDF format are not supported by the readers, though v5.1 HDF files are still supported.
