World Land Surface Temperature Atlas (WLSTA) (1992-1993)

This CD-ROM is produced by the European Space Agency (ESA) and contains land surface temperature demonstration products as estimated from the Advanced Very High Resolution Radiometer (AVHRR) sensor onboard the National Oceanic and Atmospheric Administration (NOAA) series of polar orbiters. The data used are from the full resolution (1 km) composites (decade) dataset processed in the framework of the "1 km AVHRR Global Land Data Set" collaborative project of the United States Geological Survey (USGS) EROS Data Centre (EDC), NOAA, NASA, ESA under the guidance of IGBP and CEOS. This CD-ROM contains excerpts from the full resolution land surface temperature (1 km pixel) dataset over Europe, as well as so called world monthly "climatic values" (0.5° x 0.5° grid). The full processed dataset going from July 1992 to June 1993.

This dataset is public and can be accessed from the BADC archives Please acknowledge the source of the data in any publication.

This CD-ROM contains general information documents (Readme, Algorithm Theoretical Basis Document (ATBD), and Input Output Data Document (IODD)) and data files (Full Resolution Land Surface Temperature and Climatic Land Surface Temperature).

The data files included in this CD-ROM consist of two types:

1. Excerpts at full resolution (1 km) of the Land Surface Temperature fields over Europe covering the following areal extent:

   - upper left corner: 72°N, 12°W,
   - upper right corner: 72°N, 39°E,
   - lower left corner: 34°N, 12°W,
   - lower right corner: 34°N, 39°E.
   

   The third decades (10 day composite) of December, March, June and September (4 decades) have been selected in order to be season representative of the full dataset (36 decades).
   
   The geometry is interrupted Goode Homolosine projection.
   
   The file names are ss_mmffyy_mmllyy_lstd_xxx where lstd stands for the product type (here full resolution over Europe), ss for the satellite number, mm for the month, yy for the year, ff for the first day of the decade, ll for the last day of the decade and xxx the data type.
   
   

2. Climatic Land Surface Temperatures over a month on a square half degree grid. The area covered is the whole globe:

   - upper left corner : 90°N,180°W,
   - upper right corner : 90°N, 180°E,
   - lower left corner : 90°S,180°W,
   - lower right corner : 90°S, 180°E.
   

   The time sampling is one month.
   
   The file names are ss_mm_yy_lstc_xxx where lstc stands for the product type (here climatic products), ss for the satellite number, mm for the month, yy for the year and xxx the data type.

For a summary description of the data held in this collection, see the readme article. The documentation directory contains two main documents:

1. LST Processor: Algorithm Theoretical Basis Document by Y.H. Kerr, C. Guillou, J.P. Lagouarde, F. Nerry, and C. Ottlé.
2. Input Output Data Definition Document (LST IODD) by M.A. Durand, G. Fitoussi, and C. Mehl.
