This package contains daily averages derived from 15-minute data generated by the F6 Snowfence Station, located in Taylor Valley.  Data gaps in 15 minute data were not filled to produce this dataset.    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://www.mcmlter.org/data/meteorology/tasks/task_lists.htm  2001-01-11 2009-11-27 ground condition As needed located near F6 CampID: FRLS 163.251900000000 163.251900000000 -77.608300000000 -77.608300000000 20m 20m meter [term:vocabulary] None <cntorg>McMurdo Dry Valleys LTER</cntorg> <onlink>http://mcmlter.org/</onlink> <span property="dc:title" content="McMurdo Dry Valleys LTER" class="rdf-meta element-hidden"></span> Name: Thomas Nylen Role: field crew Name: Hassan Basagic Role: field crew Name: Chris Gardner Role: data manager Name: Inigo San Gil Role: data manager Not Applicable Not Applicable Field and/or Lab Methods During the 2000-2001 field season, the McMurdo LTER established a snowfence near Lake Fryxell in eastern Taylor Valley. The station was set up to sample sensors every 30 seconds, except the sonic range which samples every 15 minutes, and send summary statistics (for example, averages and maximums) to solid-state storage modules every 15 minutes. This has resulted in approximately 20 values being recorded for final storage in every output interval.
