Data from the Total Ozone Mapping Spectrometer (TOMS), which used backscattered ultraviolet radiance to infer total column ozone measurements (gridded daily for the entire globe). This 2 CD-ROM set contains the latest version (version 7) of reflectivity data from the TOMS (Total Ozone Mapping
Spectrometer) instrument onboard the Nimbus 7 spacecraft. Data covering the entire Nimbus 7 TOMS lifetime, November 1, 1978 through May 6, 1993, are given as daily files of gridded data, as
zonal means, and as monthly averages.

A similar CD-ROM set (OPT_004A and OPT_004B) containing TOMS total ozone values is also currently available. A CD-ROM of version 7 data from the Meteor 3 TOMS instrument (August 1991 -December 1994) will be produced soon.

Abstract This computation involved: DETAILS NEEDED - COMPUTATION CREATED FOR SATELLITE COMPOSITE. deployed on NIMBUS 7 Satellite. The NASA Nimbus 7 research-and-development polar-orbiting satellite served as a stabilized, earth-oriented platform for the testing of advanced systems for sensing and collecting data in the pollution, oceanographic and meteorological disciplines. It was launched on October 24, 1978.
