3-hourly Low Resolution Brightness Temperature (BT) images
Global Brightness Temperature imagery from the Cloud Archive User Service project. This project produced a long time-series of global thermal infra-red imagery of the Earth using data from operational meteorological satellites, which was used in validating atmospheric General Circulation Models.
The source data used in CLAUS are the level B3 (reduced resolution) 10 micron radiances from operational meteorological satellites participating in the International Satellite Cloud Climatology Programme (ISCCP) and were obtained from the NASA Langley Atmospheric Sciences Data Center (LASDC).
During the CLAUS project the B3 data were processed to create a uniform latitude-longitude grid (or image) of Brightness Temperature (BT) values at a spatial resolution of 0.5 by 0.5 degrees and temporal resolution of three hours. Information at the grid point level about the satellites used in
generating each BT image, and the type of interpolation applied, is held in two supplementary quality files.
The CLAUS Lo-res data archive span the period 1983-2009 and the files are stored in the Portable Grey Map (PGM) format. This is a simple flat file binary format preceded by an ASCII (readable) header that contains information such as the image dimensions and version number.
For detailed information about the CLAUS data (processing, quality, etc) please see available documentation (Docs).

Name Version Files are stored in the Portable Grey Map (PGM) format. This is a simple flat file binary format preceded by an ASCII (readable) header that contains information such as the image dimensions and version number.
There are 3 files for each day i.e. one data file (*.2bt) for the CLAUS Brightness Temperature Image Data and two ancillary files: *.2cs for CLAUS Contributing Satellite Image Data and *.2iq for CLAUS Interpolation Quality Image Data.
See PGM File Format explained documentation under Docs.

Data obtained during the period from April 1997 to December 1999 by satellites. Latest version of the CLAUS data (4.7) was acquired as is from Dr Gary Robinson (University of Reading) in December 2009, and is stored in the BADC archive. Data updates from June 2006 to June 2009 were obtained from the data supplier in May 2013.
