As part of the Long Term Ecological Research in the McMurdo Dry Valleys of Antarctica, meteorological data are collected from various locations throughout the McMurdo Dry Valleys of Antarctica. These files contain data for the Beacon Valley Meteorological Station daily averages, as derived from the 15-min data. Data gaps in 15 minute data were not filled to produce this dataset. Beacon Valley Meteorological Station ceased operations in the 2012 season.
