TOMS/N7 Near UV Aerosol Index and LER 1-Orbit L2 50x50 km
As part of the NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, this projects describes a multi-decadal Fundamental Climate Data Record (FCDR) of calibrated radiances as well as an Earth System Data Record (ESDR) of aerosol properties over the continents derived from a 40-year record of satellite near-UV observations by three sensors. The TOMS Nimbus 7 version 2 Level-2 orbital data product consists of cloud fraction, cloud optical depth, normalized radiance, reflectivity, residue, and UV aerosol index at approximately 50x50 km resolution (at nadir). This product also contains ancillary variables for ocean corrected surface albedo and terrain pressure. Total Ozone Mapping Spectrometer (TOMS) instruments have been successfully flown in orbit aboard the Nimbus-7(Nov. 1978 - May 1993), Meteor-3 (Aug. 1991 - Dec. 1994), Earth Probe (June 1996 - December 2005), and ADEOS (Sep. 1996 - June 1997) satellites. These Level-2 data are stored in the Hierarchical Data Format 5 (HDF5) and are available from the Goddard Earth Sciences (GES) Data and Information Services Center (DISC).

Processing Level
2
- Quality Quality improvements are envisioned. The TOMSN7AER data are based on the TOMS Collection 2 L1B data. Regarding TOMSN7AER vs. TOMSN7L2, There are only 14 Orbits that exist in Collection 1 but not in Collection 2. At the very beginning of the record, Orbits 00107 to 00114 do not exist in Collection 2. At the very end of the record, Orbit 73388 does not exist in Collection 2.
