Gap-filled half-hourly meteorological driving data for CLM from 1985 - 2013. The original datasets are from the Barrow, AK station of NOAA/Earth System Laboratory, Global Monitoring Division (http://www.esrl.noaa.gov/gmd/obop/brw/
), and NOAA's National Climate Data Center. The latter source provides daily precipitation at the Barrow Airport (station code - GHCND:USW00027502, station name - Barrow W Post W. Rogers Airport, AK, US), because the former datasets appear large amount of data missing for precipitation. Gap-filling generally follows AmeriFlux procedure and others.
