The SKOPE I prototype serves two types of data:

1. Four raster data sets.

• Represent PaleoCAR-retrodicted environmental conditions at 30"x30" resolution over a  13° x 12° geographic region of the Southwest US for each of 2000 years.  
• Graphed as a function of time for a single selected point on the map.  
• Each data set is stored on the server as a single 8.4 GB file (in GeoTIFF format).
• The GDAL program gdallocationinfo is used to extract values from these four files as needed by the web application.

2. Color map tile representations of two of the PaleoCAR retrodictions described above.

• Overlayed on the map in the web application.
• Completely precomputed at 13 different zoom levels.
• Requires 34,410 PNG files per year (average ~2 KB per PNG file).
• For 2000 years the total is 68,820,000 files per data set (137,640,000 files for two data sets).
• The map tile images for each of these data sets require ~140 GB of storage (estimated).
• Precomputing these map tiles from the raster data sets took 3 weeks to complete on ROGER.
