Climate Data online (CDO), Version 2
NCDC has released an updated version, Version 2.0, of its popular Climate Data Online service. Climate Data online or CDO provides access to climate data products through a simple, searchable online web mapping service. Users can find a variety of NCDC products via CDO including the Global Historical Climatology Network-Daily and the new 1981-2010 Annual, Monthly and Daily 30-year Normals. You can check out CDO at: www.ncdc.noaa.gov/cdo-web/search. CDO v. 1.0 applications will continue to be available, however these will transition to the new system and be discontinued throughout 2012 as the products are replaced in the updated CDO program.
