The final iteration of the TOMS data, version 7, is available NOW from the TOMS group's Nimbus-7 page. ASCII data and GIF images of the daily data are available. This data set utilizes updated calibration and an algorithm improved from previous versions. The Goddard DAAC will distribute both data products, and provide them on CD-ROM. Version 7 level 3 data will also be available on the DAAC's ftp service, along with 1 degree by 1 degree monthly means.
