  As part of the Long Term Ecological Research in the McMurdo Dry Valleys of Antarctica, meteorological data was collected from various locations throughout Beacon, Taylor, Wright and Victoria Valleys. These files contain averages derived from data for the Garwood Ice Cliff meteorology station. This station reported data for about a year, during 2011. On January 10, 2012 the station was being transferred to the custody of the MCM LTER program by Joe Levy (UT), completing of the handover on the Austral summer of 2014. The GAFM station was moved ~5 m from its original site in 2013 (out of the stream bed). GAFM no longer used, dismantled.

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.org/meteorological-task-listsNote, soil temperatures and surface changes did not offer good data as of now for this station - no averages are derived.

 The Garwood Ice Cliff meteorological station was added to the McMurdo Dry Valley network in the 2012-13 field season.            GAFM transfer process was proposed to be finished off on 2013, but eventually was abandoned, dismantled.         The GAFM station was moved ~5 m from its original site in 2013 (out of the stream bed). At this time, the three 107 temperature probes were placed in a vertical profile (10, 5, and 0 cm), similar to the other AWS (recording in Celsius)         Air temp and RH are at 3 m, along with wind direction and speed. Incoming and outgoing SW and LW are also at 3 m, but were oriented parallel to the ground surface (rather than normal) in order to capture radiative flux into/out of the ice cliff. In 2013-2014, these sensors were replaced with a single NR-LITE2 net rad sensor which is oriented in a typical, ground-normal orientation (the original sensors did not survive contact with a katabatic wind storm some time over the winter). The SR is also at 3m and points towards the ice cliff. This instrument died in 2013 and failed in 2013-2014. I've got a replacement we can install this field season, since it is a useful measurement.           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 15 minutes. This has resulted in approximately20 values being recorded for final storage in every output interval.
