As part of the Long Term Ecological Research in the McMurdo Dry Valleys of Antarctica, meteorological data was collected from various locations throughout Taylor, Wright and Victoria Valleys. These files contain daily averages derived from the data for the Commonwealth Glacier meteorology station (in Taylor Valley).
Meteorological data is collected year-round at each of the stations in the McMurdo Dry Valleys of Antarctica. After retrieving this data (usually every January), the parameters that are recorded are processed from level 0 (raw) to level 1 (processed, provided on the web). The raw data file descriptions and task lists summarize what was done to get from level 0 to level 1 for all station found at the following address: http://mcmlter.lternet.edu/data/meteorology/tasks/task_lists.htm

At the start of the 1993-1994 field season, the Commonwealth Glacier meteorological station was constructed at the same coordinates as stake 11 on the glacier's mass balance grid. The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and maximums) to solid-state storage modules every:Â Â Â Â 3 hours between November 22 and December 3, 1993,Â Â 30 minutes between December 3 and December 24, 1993,Â Â 30 minutes for the main array andamp; every 24 hours for the max/min thermal infrared between December 24, 1993 and; January 12, 1994,Â Â 6 hours for the main array andamp; every 24 hours for the max/min thermal infrared between January 12, 1994 and; January 18, 1994,Â Â 20 minutes between January 18, 1994 and November 27, 1995,Â Â 15 minutes thereafter.Â Â Â Â Â This has resulted in approximately 20 values being recorded for final storage in every output interval.Â Â Sampling and Averaging Intervals Â Â Â Â For Sampling frequency and Data Logger output and averaging intervals please visit Â Â Â Â Â Â http://mcmlter.lternet.edu/data/meteorology/methods/Interval_Dates.pdf Â Â Seasonal Task Summary Â Â Â Â To view the data post-processing steps for each season please visit: Â Â Â Â Â Â http://mcmlter.lternet.edu/data/meteorology/tasks/task_lists.htm
