Air and ground temperature, air humidity and site characterization data from the Canadian Shield taiga near Kennady Lake, Northwest Territories, Canada
Abstract
These data were collected near Kennady Lake Northwest Territories, Canada. Data comprise air and ground temperature and air humidity measurements and detailed metadata describing surface and vegetation conditions at each site. Study plots measuring 15 m x 15 m were selected to represent different facets of the landscape. For each plot, four sub-plots were selected to represent the diversity of surface characteristics within the plot area. Metadata for each plot include surface features, disturbances and topography. Sub-plot metadata include vegetation type, abundance, and height as well as leaf-area index as measured by an accuPAR. In the centre of several of the plots, thermistor cables were installed into a borehole with sensors between 0.5 and 3 m deep. At each sub-plot, a single-channel temperature logger was installed approximately 10 cm below the ground surface. Four air temperature and humidity sensors were installed 2 m above the ground surface and ten temperature sensors were drilled into bedrock. Instruments for near-surface and air temperature were programmed to record data every 20 minutes, whereas temperatures in boreholes are recorded every 60 minutes. All instruments were set to UTC time. Time series have been aggregated to hourly and daily averages. The period of data coverage begins in July 2017.
