Latest SST data from the consolidated ABT dataset


FTP access to ASST products

Sea-Surface Temperatures products for the time period June 1995 - January 2001 are available from our anonymous FTP site.

There are 2 types of products available to donwload - daily SST files, which contain each day's data in a separate file, and spatio-temporally averaged maps. For more detailed information, please, refer to an on-line booklet.

Please, note that it is very important that you set your ftp client to use BINARY transfer mode before beginning download.

  1. FTP into atsabt.ag.rl.ac.uk
  2. Log on as ANONYMOUS, using your E-MAIL ADDRESS as password
  3. Set to the appropriate directory as follows cd pub/sstdata/ssts then ftp the files in the usual way

If you have any problems, please email support@www.atsr.rl.ac.uk.



SST product format

The first six characters will be atsr1_ or atsr2_ as appropriate. The following eight numbers give the data as yyyymmdd where yyyy is the year, mm the month of the year, and dd the day of the month. Thus the data acquired by ATSR-2 on 1st June 1995 is contained in atsr2_19950601.sst.

The format for the daily SST files is as follows:

Variable Description Bytes
day Modified Julian Day 4
second Seconds in day 4
lat_cell Latitude cell 2
long_cell Longitude cell 2
sst_dual_2chan 4 channel SST (cK) 4
sst_dual_3chan 6 channel SST (cK) 4
sst_nadir_2chan 2 channel SST (cK) 4
sst_nadir_3chan 3 channel SST (cK) 4
nadir_pixels No. of nadir pixels 2
forward_pixels No. of forward pixels 2
across_pixel Across-track pixel 2
configuration Configuration info 2
confidence Confidence info 4

This gives rise to approximately 9.5Mbytes per daily file, with the zipped version of the files being about half this size.
