Summary
A brief description of the data.

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). These CD-ROM's (version 7) cover the operation of the TOMS instruments on the Meteor-3 and Nimbus-7 satellites, over the period November 1978 to December 1994. This dataset is public.

Content
The actual data being described by this document. NB, in the case of data granules, this content may just be a reference to an ingested CSML or CDML file.

Introduction

The Total Ozone Mapping Spectrometer (TOMS) is an instrument built and operated by the National Aeronautics and Space Administration (NASA). The instrument uses backscattered ultraviolet radiance to infer total column ozone measurements. The data consists of daily gridded averages of total ozone covering the entire globe. The original Nimbus-7 TOMS operated from November 1978 until May 1993. Meteor-3 TOMS was launched in August 1991 and operated until December 1994. These CDs contain the total ozone and UV radiance data.

Two new TOMS instruments have began operation since the CDs were produced. Data from both these new instruments are available as the BADC's TOMS dataset.

Data Access

The set of 6 CDs are available freely using the World Wide Web or anonymous FTP. CD-ROM's (version 8) can be ordered from GSFC.

Data availability and file format

Data files in the TOMS archive are in ASCII format, while images are in the GIF format.

Documentation and Links to further information and references

Each CD has a documentation directory called document at the top level. These directories contain readme files and user guides for the Meteor-3 and Nimbus-7 data.

For further information please refer to the NASA's TOMS home page at GSFC.

Lineage
Summary of the origins of the dataset, e.g.: "Dataset produced from NASA MODIS instrument on Terra and collected at the University of York's groundstation 1999-2003 and a copy provided to NEODC in June 2007".

Data collected by NASA and published on CD-ROM. A copy of the data were obtained by the BADC to assist in data access and to ensure long term preservation.
