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. NOTE: This LTER data portal display does not contain important maintenance/log information.
