These files contain data for the Lake Bonney Snowfence station (in Taylor Valley). Measurements at this temporary met station ceased on April 2006.  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 The last usable data was recorded on January 4, 2006 @ 14:00. There was some intermittent data recorded during the 2006-2007 season, but not much. The station was modified in late January 2007 to support another experiment  2001-01-01 2006-12-31 ground condition As needed ID: BOYS 162.313200000000 162.313200000000 -77.724500000000 -77.724500000000 108m 108m 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: Hassan Basagic Role: field crew Name: Thomas Nylen Role: field crew 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 above (south) of the west lobe of Lake Bonney in western 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.
