Soil moisture, temperature, and electrical conductivity data from the black sand extended growing season length experiment, 2018 - ongoing, hourly.

As a result of climate change, the Rocky Mountain Front Range is
experiencing warmer summers and earlier snowmelt. Due to the
importance of snow for regulating soil temperature, growing season
length, and available moisture in alpine ecosystems, even small
shifts in the snow-free period could have large impacts. The focus
of the Growing Season Length Experiment is to examine how
terrain-related differences in climate exposure influence the way
alpine habitats respond to climate change via earlier snowmelt. To
simulate how changes in growing season length may affect biotic and
abiotic components, NWT LTER researchers established 5 experimental
sites each containing a pair 10 x 40m rectangular plots. These
blocks include north and south facing aspects, subalpine and alpine
tundra meadows in a range of hydrological conditions (e.g. dry
meadows, moist meadows, wet meadows). We accelerated snowmelt in one
plot of each block by adding chemically inert black sand, while
keeping the second plot as an unmanipulated control (black sand was
added to these plots after snow had naturally melted). This dataset
includes measurements of soil temperature, moisture, and electrical
conductivity.
