The files are cloud-free composites made using all the available archived DMSP-OLS smooth resolution data for calendar years. In cases where two satellites were collecting data - two composites were produced. The products are 30 arc second grids, spanning -180 to 180 degrees longitude and -65 to 75 degrees latitude.

NOTE: Disk space required for compressed data is ~300 MB and uncompressed data is ~3 GB.

NOTE: These files are gzipped and added to tar files under linux. Winzip and some other windows utilities may convert newlines in the data into a windows linefeed. To avoid this in WinZip go to -> Options -> Configuration -> Miscellaneous and uncheck the 'TAR file smart CR/LF conversion'.
