These files contain data for the Lake Bonney Snowfence station (in Taylor Valley). Measurements at this temporary met station ceased on April 2006.

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/BOYS_AIRPAR.csv BOYS_AIRPAR eng; US McMurdo Dry Valleys LTER BOYS_AIRPAR Data Source Definition : Bonney Snowfence station Air PAR Units Record Delimiter : \n Number of Header Lines : 27 Number of Footer Lines : 1 Orientation : Column Quote Character : "Field Delimiter : , false DATASET_CODE Code for given set of information for Bonney Snowfence meteorology station METLOCID Location code for Bonney Snowfence meteorology station DATE_TIME Date/time of sample (New Zealand DST, +13 UTC) Date Time Format: MM/DD/YYYY HH24:MI PAR_AIR_PLUS1_5M Photosynthetically active radiation AIRPAR_COMMENTS Noted comments by the investigator about the particular measure of AIR_PAR_ DBF https://mcm.lternet.edu/sites/default/files/BOYS_AIRPAR.csv https://mcm.lternet.edu/sites/default/files/BOYS_AIRT.csv BOYS_AIRT eng; US McMurdo Dry Valleys LTER BOYS_AIRT Data Source Definition : Bonney Snowfence Station BOYS_AIRT Record Delimiter : \n Number of Header Lines : 27 Number of Footer Lines : 1 Orientation : Column Quote Character : "Field Delimiter : , false DATASET_CODE Code for given set of information for Bonney Snowfence meteorology station METLOCID Location code for Bonney Snowfence meteorology station DATE_TIME Date/time of sample (New Zealand DST, +13 UTC) Date Time Format: MM/DD/YYYY HH24:MI AIRT1_3M Average air temperature at 1.3 m above ground AIRT_COMMENTS Noted comments by the investigator about the particular measure of air temperature DBF https://mcm.lternet.edu/sites/default/files/BOYS_AIRT.csv https://mcm.lternet.edu/sites/default/files/BOYS_SOILPAR.csv BOYS_SOILPAR eng; US McMurdo Dry Valleys LTER BOYS_SOILPAR Data Source Definition : Bonney Snowfence Station Soil PAR Units Record Delimiter : \n Number of Header Lines : 27 Number of Footer Lines : 1 Orientation : Column Quote Character : "Field Delimiter : , false DATASET_CODE Code for given set of information for Bonney Snowfence meteorology station METLOCID Location code for Bonney Snowfence meteorology station DATE_TIME Date/time of sample (New Zealand DST, +13 UTC) Date Time Format: MM/DD/YYYY HH24:MI PAR_SOIL_PLUS3_6M Photosynthetically active radiation 3.6 m east of snowfence PAR_SOIL_PLUS1_8M Photosynthetically active radiation 1.8 m east of snowfence SOILPAR_COMMENTS Noted comments by the investigator about the particular measure of SOIL_PAR_ DBF https://mcm.lternet.edu/sites/default/files/BOYS_SOILPAR.csv https://mcm.lternet.edu/sites/default/files/data/BOYS_SURFCHANGE.csv BOYS_SURFCHANGE eng; US McMurdo Dry Valleys LTER BOYS_SURFCHANGE Data Source Definition : Bonney Snowfence Station Snow Height Surface Change spreadsheet description and units used Record Delimiter : \n Number of Header Lines : 27 Number of Footer Lines : 1 Orientation : Column Quote Character : "Field Delimiter : , false DATASET_CODE Code for given set of information for Bonney Snowfence meteorology station METLOCID Location code for Bonney Snowfence meteorology station DATE_TIME Date/time of sample (New Zealand DST, +13 UTC) Date Time Format: MM/DD/YYYY HH24:MI SURFCHANGE_CM Surface Height Change -snow height / sediment accumulation or loss SURFCHANGE_COMMENTS Noted comments by the investigator about the particular measure of surface change DBF https://mcm.lternet.edu/sites/default/files/data/BOYS_SURFCHANGE.csv https://mcm.lternet.edu/sites/default/files/BOYS_SOILT.csv BOYS_SOILT eng; US McMurdo Dry Valleys LTER BOYS_SOILT Data Source Definition : Bonney Snowfence Station Soil Temperature Units Record Delimiter : \n Number of Header Lines : 27 Number of Footer Lines : 1 Orientation : Column Quote Character : "Field Delimiter : , false DATASET_CODE Code for given set of information for Bonney Snowfence meteorology station METLOCID Location code for Bonney Snowfence meteorology station- BOYS DATE_TIME Date/time of sample (New Zealand DST, +13 UTC) Date Time Format: MM/DD/YYYY HH24:MI SOILT_4_5M Surface soil temperature at 4.5 m west of snowfence SOILT+1M Surface soil temperature at 1 m east of snowfence SOILT+1_9M Surface soil temperature at 1.9 m east of snowfence SOILT+3_8M Surface soil temperature at 3.8 m east of snowfence SOILT_COMMENTS Noted comments by the investigator about the particular measure of SOILT DBF https://mcm.lternet.edu/sites/default/files/BOYS_SOILT.csv dataset  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.
