Near-surface, soil, and air temperature data acquired across multiple locations in the Tehachapi mountains at Tejon Ranch, California, 2011-2017

These temperature records were collected as part of a larger study
relating microclimates to tree seedling survival in southern
California mountains. These temperature records are for studies in the
Tehachapi mountains at Tejon Ranch (Lat 34.967, Long -118.583,
elevation 1600-1700 m, www.tejonranch.com). Temperature sensors were
located at 23 sites across the Tehachapi foothills. Sites were
selected to sample topographic variation in surface and air
temperatures within a narrow range of elevations on northeast to
southwest-facing slopes, ridges and valleys. To characterize surface
temperature variation within a site, 21 sensors were arranged in an
identical pattern around and in six, 5x5 m experimental gardens. An
additional 18 sensors were placed along three transects over the
landscape running N-S. They were placed strategically to sample
topographic inflection points (hill tops and valley bottoms) as well
as north and south facing slopes. Temperatures were recorded on a 10
or 20-minute interval, depending on the sensor. using HOBO (Onset,
www.onsetcomp.com) devices.
