The research and science objectives of the Shidler Tallgrass Prairie site are as follows: 1) Examine the differences, similarities, and environmental controls in canopy photosynthetic characteristics of diffuse and direct photosynthetically active radiation; 2) Quantify carbon exchange in a mid-latitude tallgrass prairie; 3) Examine the magnitudes of daytime and night-time CO2 fluxes during different times in the year; 4) Study the seasonal variation in carbon exchange in terms of relevant environmental variables; 5) Estimate the fraction of incident photosynthetically active radiation absorbed by the photosynthetic components of a plant canopy.

PhenoCam Images and Derived Time Series Data
PhenoCams are high-resolution digital cameras that take repeated images of studied ecosystems and provide quantitative information about the canopy phenology. The PhenoCam Network coordinates the camera installation and data reporting/analyses across sites in the Americas, providing automated, near-surface remote sensing of canopy phenology across a range of ecosystems and climate zones. Use of PhenoCam images / data should follow the PhenoCam Data Use Policy .
No PhenoCam data for this siteGeoNEX Data Products
GeoNEX led by NASA Earth eXchange (NEX) is a collaborative effort for generating Earth monitoring products from the new generation of geostationary satellite sensors. GeoNEX has produced a suite of geostationary data products including surface reflectance, land surface temperature, surface solar radiation, and many others.
The GeoNEX Common Grid locates GeoNEX data in the geographic (latitude/longitude) projection. Pixels (grid cells) are created at regular 0.005°, 0.01°, and 0.02° resolutions.
GeoNEX pixels below cover the area 0.06° x 0.06° around and including site US-Shd, 36.9333, -96.6833.
