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).
