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 at the San Joaquin Experimental Range (Lat 37.083, Long -119.716, elevation 210-520 m, http://www.fs.fed.us/psw/ef/san_joaquin/). Temperature sensors were located at 23 sites across the landscape. 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, 5×5 m experimental gardens. An additional 18 sensors were placed along three transects over the landscape running E-W. 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, http://www.onsetcomp.com) devices.

Additional Information

This data is part of a larger dataset of soil, near-surface, and temperature data, including meteorological data and seedling data. These datasets were acquired across multiple locations in southern California mountains from 2011 to 2017. All project data and down-scaled climate grids of the region are available at http://m2m.biogeog.ucsb.edu.

Funding was provided by the U.S. National Science Foundation Macrosystems Biology Program, project EF-1065864, “Do microenvironments govern macroecology?” and by NSF EAGER-NEON Grant EF-1550653, “How do microscale biophysical processes mediate ecosystem shifts during climate change-driven drought?”
