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 ozone 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. Software is included to image the data. For scientific investigators, a similar CD-ROM containing TOMS surface reflectivity values is planned. A CD-ROM of version 7 data from the Meteor 3 TOMS instrument (August 1991 - December 1994) will be produced this summer.

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 CD-ROM contains one file for each day from November 1, 1978 to March 6, 1993 (with a few missing days). Each file contains data representing the relative daily areal exposures of ultraviolet (UV) radiation effective in causing skin irritation, computed at each 1 degree latitude by 1.25 degree longitude pixel, between latitudes 65S and 65N. These data were derived from measurements made by NASA's Total Ozone Mapping Spectrometer (TOMS), which was flown aboard the Nimbus-7 satellite.
