Summary
A brief description of the data.

An infra-red radiometer capable of measuring sea surface temperature to better than 0.3K. The cd-rom dataset consists of two data products: (a) Spatially averaged sea surface temperatures (ASSTs) and (b) Time averaged global maps. The ASSTs are provided daily in half-degree cells together with temporal and positional information. The data cover the period August 1991 to July 1995. This dataset is public.

Introduction

The data on this 2 CD set is derived from the the first Along-Track Scanning Radiometer (ATSR-1) which is a four-channel, dual-view, infra-red radiometer capable of measuring Sea Surface Temperature to very high accuracy (better the 0.3K). The instrument was launched on the ESA remote sensing satellite (ERS-1) in July 1991.

The dataset consists of two types of data product: (a) Spatially averaged sea surface temperatures (ASSTs) and (b) Time averaged global maps. The ASSTs are provided daily in half-degree cells together with with temporal and positional confidence information. The time-averaged global maps are provided at half degree resolution averaged over 5 day and 1 month periods. The data on the CDs cover the four year period from August 1991 to July 1995 inclusive.

The Principal Investigator for ATSR-1 is Chris Mutlow at the STFC Rutherford Appleton Laboratory (RAL).

Data Access

This dataset is public. The data are held on CD-ROM at the BADC and are available online for browsing purposes. Please acknowledge the source of the data in any publication.

Access to data - File format

The data are held on CD-ROM at the BADC and are available online for browsing purposes.

The data are stored as 2-byte and 4-byte integers in fixed-length records. The choice of this simple format means that it should be a relatively simple matter to read the data on a variety of different computer set-ups and operating systems. Software is provided on the CDs to read and plot the data.

Documentation, Links to further information and references

The documentation on the CD-ROM has been extracted and made available through this interface. This gives an inventory of the data on the CD and an outline of the data format and software available on the CD for reading and plotting the data.

There is a great deal of useful information about these and other ATSR data products from the ATSR group web pages, including some sample images and data updates for the time period June 1995 to January 2001, available from anonymous FTP. The NERC Earth Observation Data Centre (NEODC) also holds ATSR/AATSR products.

Information about the ATSR instrument and its successors ATSR-2 and AATSR may be found on the ATSR web pages. This includes more detailed descriptions of the contents of the CD-ROMs and information on other products from ATSR.

The ATSR instrument design is described in Edwards et al. (1990) J. British Interplan. Soc., 43, pp160-180. Results of the validation programme are reported in Mutlow et al. (1995) J. Geophys. Res. 99 pp. 575-588 and Barton et al. (1995) J. Atmos. Oceanic Technol. 12 pp. 290-300.
