This package contains monthly averages from the Beacon Valley Meteorological Station (BENM), located in Beacon Valley. These data were derived from 15-minute data. BENM was established in January 2000 and removed in December 2012. Name: Thomas Nylen Role: field crew Name: Renée F. Brown Role: data manager Name: Inigo San Gil Role: former data manager completed McMurdo Dry Valleys LTER http://mcmlter.org/ unknown On February 12, 2003, wind direction (WDIR) values were corrected by Thomas Nylen for a systematic error in the measurement created by improper wiring. The wind sensor still worked, but the values were systematically off. The wind direction is off by 180 degrees and mirrored around the north-south axis. For example a wind direction of 160 degrees was corrected by adding 180 degrees to it (340 or -20) and takING the mirror value of that, i.e. 20 degrees. Beacon ceases operations in 2012/2013 season Andrew Fountain: First, the station was installed to support the soil experiments in Beacon that are no longer being conducted, so its original purpose no longer supports its operation. Second, the station is costly in terms of helicopter hours that could be better spent in maintaining the stations in the valleys in which we work particularly our expansion into Miers. Third, the current met station at Lake Hoare, our longest running station in the valleys, is endangered by rising lake levels. It has perhaps another year or two at most given current rates of increase. To plan for its removal to a new spot, we need to erect a new station at a new site close by (selection is underway) and have the two stations run simultaneously for a year or so to characterize the small meteorological differences between sites. We do not have another station to do that and propose to move the Beacon Station to Hoare. Finally, Beacon Valley may be the best monitored valley in the region for air temperature and other met variables because of other projects including Sletten, Marchant, and MacKay. Sletten's station in Beacon is not far from ours, it has a relatively long data record, and I'm sure we could use his data if needed. English ground condition 2000-11-01 2012-12-31 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 1for all station found at the following address: http://mcmlter.lternet.edu/data/meteorology/tasks/task_lists.htm https://mcm.lternet.edu/sites/default/files/data/BENM_AIRT_MONTHLY.csv BENM_AIRT_MONTHLY eng; US McMurdo Dry Valleys LTER BENM_AIRT_MONTHLY Data Source Definition : Description and details of the spreadsheet containing monthly averages of the Beacon Met station Record Delimiter : \n Number of Header Lines : 44 Number of Footer Lines : 1 Orientation : Column Field Delimiter : , false METLOCID Location code for this met station DATE_TIME Date sample was collected Date Time Format: mm/dd/yyyy AVG_AIRT3M Average air temperature at 3 m above ground STD_AIRT3M Standard deviation for the air temperature at 3 m above ground MIN_AIRT3M Minimum value of the air temperature at 3 m above ground MAX_AIRT3M Maximum value for the air temperature at 3 m above ground N_AIRT3M Number of observations for this average DBF https://mcm.lternet.edu/sites/default/files/data/BENM_AIRT_MONTHLY.csv https://mcm.lternet.edu/sites/default/files/data/BENM_RADN_MONTHLY.csv BENM_RADN_MONTHLY eng; US McMurdo Dry Valleys LTER BENM_RADN_MONTHLY Data Source Definition : Description and details of the spreadsheet containing solar radiation monthly averages of the Beacon Met station Record Delimiter : \r\n Number of Header Lines : 44 Number of Footer Lines : 1 Orientation : Column Field Delimiter : , false METLOCID Location code for this met station DATE_TIME Date sample was collected Date Time Format: mm/dd/yyyy AVG_PAR Average photosynthetically active radiation (PAR).

It was established in Beacon Valley. 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 approximately 20 values being recorded for final storage in every output interval.
