*README* The WSSI_Archive directory has moved. The new address is https://ftp.wpc.ncep.noaa.gov/WSSI_Archive/ Due to storage demands we will only be keeping the last 30 days of data at the above address. All the WSSI data is still being archived, but on an offline server. Please email Josh Kastman (joshua.kastman@noaa.gov) to request data. In your request please include the WFO(s) and date range. You can also request CONUS perspective data and the raw WSSI output for the CONUS (geoTiff format).
