Soil temperature data for Saddle snowfence, 1992 - 1995.

A snowfence was built in 1993 on the Niwot Ridge Saddle grid to determine the effects of changes in snowpack on a number of variables, one of which was soil temperature. The study area was 60m x 125m. Soil temperatures were measured at two depths (0 and 15 cm) at each of 13 locations within the snowfence experiment area. Soil temperatures were measured at the same depths at each of 6 control locations outside of but near the snowfence experiment area. These measurements were made weekly to biweekly using fixed thermistors and data loggers. Sampling locations were each given a unique point identification number in order that these data could be incorporated into the Saddle GIS. The snowfence was oriented in a north/south direction and was 60m long. Each of the point identification numbers had a coordinate within the experiment area. The first number of the coordinate was the distance in m from the snowfence in an east/west direction, negative numbers being west of the snowfence and positive numbers being east of the fence. The second number in the coordinate was the distance in m from the southern terminus of the snowfence in a northerly direction. The point identification numbers and coordinates were: 203 (-40,30), 217 (-30,30), 231 (-20,30), 245 (-10,30), 252 (-5,30), 259 (5,30), 266 (10,30), 281 (20,30), 295 (30,30), 309 (40,30), 323 (50,30), 337 (60,30). Controls were located outside of the snowfence experiment area: 113 (approximately 10 m south of the -30,0 coordinate) in the Acomastylidetum rossii vegetation association, 114 (approximately 11 m south of the -25,0 coordinate) in the Acomastylidetum rossii vegetation association, 115 (approximately 8 m south of the 55,0 coordinate) in the Kobresietum myosuroidis vegetation association, 116 (approximately 5 m north of the 50,60 coordinate) in the Kobresietum myosuroidis vegetation association, 117 (approximately 3 m north of the -23,60 coordinate) in the Rhodiolo integrifoliae vegetation association, 118 (approximately 5 m north of the -21,60 coordinate) in the Rhodiolo integrifoliae vegetation association.
