WEATHER IMAGE ARCHIVE

ORNL maintains a weather image archive of satellite, radar, surface analysis, upper air, wind field, and model output.  Although the archive is too large to maintain an online presence; DOE-users can inquire about the availability of images at birdwellkr@ornl.gov.  Weather imagery archiving began about May 2000 and wind field (CAPARS output) data archiving began about September 2001.  Please note that this service is only available to DOE and DOE-contractor users.
