Changing Seasonality of Tundra Plant-Soil Interactions

This dataset consists of irradiance, temperature, relative humidity, and soil moisture readings collected by an array of data loggers on the Alaska North Slope tundra. A frame of crossed steel straps support the sensor head about 0.5 meters above the tundra. The irradiance sensors in the heads are o...

Description
Summary:This dataset consists of irradiance, temperature, relative humidity, and soil moisture readings collected by an array of data loggers on the Alaska North Slope tundra. A frame of crossed steel straps support the sensor head about 0.5 meters above the tundra. The irradiance sensors in the heads are of two kinds: Photosynthetically Active Radiation (PAR, in units of microeinsteins), and solar radiation (SR, in units of watts per meter squared). The two spectral bands allow calculating Normalized Difference Vegetation Index (NDVI), a "greenness index" (this was the main purpose of this part of the project). Data from each site allows tracking the season-long greenness changes in a patch of tundra on the order of one square meter in size. Algorithms for data processing and summarized results may be obtained from the project PIs, but this archive contains only the raw data in tab-delimited ASCII files.
