These files contain data for the Lake Bonney Snowfence station (in Taylor Valley). Measurements at this temporary met station ceased on April 2006. Here we offer the daily averages based on the 15-min frequency data for the Lake Bonney Snowfence station.

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   https://mcm.lternet.edu/sites/default/files/data/BOYS_AIRPAR_DAILY.csv BOYS_AIRPAR_DAILY eng; US McMurdo Dry Valleys LTER BOYS_AIRPAR_DAILY Data Source Definition : Description and details of the spreadsheet containing daily averages of the Bonney Snowfence AirPar measurements Record Delimiter : \n Number of Header Lines : 42 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_AIR_PLUS1_5M Average of the photosynthetically active radiation STDDEV_PAR_AIR_PLUS1_5M Standard deviation for the Photosynthetically active radiation distribution MIN_PAR_AIR_PLUS1_5M Minimum value of the Photosynthetically active radiation MAX_PAR_AIR_PLUS1_5M Maximum value for the Photosynthetically active radiation N_PAR_AIR_PLUS1_5M Number of observations for this average DBF https://mcm.lternet.edu/sites/default/files/data/BOYS_AIRPAR_DAILY.csv https://mcm.lternet.edu/sites/default/files/data/BOYS_AIRT_DAILY.csv BOYS_AIRT_DAILY eng; US McMurdo Dry Valleys LTER BOYS_AIRT_DAILY Data Source Definition : Description and details of the spreadsheet containing daily averages of the Bonney Snowfence Met station air tempeature measurements Record Delimiter : \n Number of Header Lines : 42 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_AIRT1_3M Average air temperature at 1.3 m above ground STD_AIRT1_3M Standard deviation for the air temperature at 1.3 m above ground MIN_AIRT1_3M Minimum value of the air temperature at 1.3 m above ground MAX_AIRT1_3M Maximum value for the air temperature at 1.3 m above ground N_AIRT1_3M Number of observations for this average DBF https://mcm.lternet.edu/sites/default/files/data/BOYS_AIRT_DAILY.csv https://mcm.lternet.edu/sites/default/files/data/BOYS_SURFCHANGE_DAILY.csv BOYS_SURFCHANGE_DAILY eng; US McMurdo Dry Valleys LTER BOYS_SURFCHANGE_DAILY Data Source Definition : Description and details of the spreadsheet containing daily averages for the ice surface change at the Bonney Snowfence met station Record Delimiter : \n Number of Header Lines : 42 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_SURFCHANGE_CM Average surface change - snowfall / sediment accumulation or loss STD_SURFCHANGE_CM Standard deviation for the surface change - snowfall / sediment accumulation or loss MIN_SURFCHANGE_CM Minimum value of the surface change - snowfall / sediment accumulation or loss MAX_SURFCHANGE_CM Maximum value for the surface - snowfall / sediment accumulation or loss N_SURFCHANGE_CM Number of observations for this average DBF https://mcm.lternet.edu/sites/default/files/data/BOYS_SURFCHANGE_DAILY.csv https://mcm.lternet.edu/sites/default/files/data/BOYS_SOILT_DAILY.csv BOYS_SOILT_DAILY eng; US McMurdo Dry Valleys LTER BOYS_SOILT_DAILY Data Source Definition : Description and details of the spreadsheet containing daily averages of the bonney Snowfence Met station Record Delimiter : \n Number of Header Lines : 42 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_SOILT_4_5M Average soil temperature at 4.5 m west of snowfence STD_SOILT_4_5M Standard deviation for the soil temperature at 4.5 m west of snowfence MIN_SOILT_4_5M Minimum value of the soil temperature at 4.5 m west of snowfence MAX_SOILT_4_5M Maximum value for the air temperature at 4.5 m west of snowfence N_SOILT_4_5M Number of observations for this average AVG_SOILT+1M Average soil temperature at 1 m east of snowfence STD_SOILT+1M Standard deviation for the soil temperature at 1 m east of snowfence MIN_SOILT+1M Minimum value of the soil temperature at 1 m east of snowfence MAX_SOILT+1M Maximum value of the soil temperature at 1 m east of snowfence N_SOILT+1M Number of observations for the daily stats.

South end of snow fence still in need of repair. Made temporary fix.  7. Swapped out one SM4M for another on January 4, 2006 @ 1400.   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.
