| Description: | Dry hillslope underlain by ice rich permafrost and now covered with native grasses and managed as a rustic golf course. The land clearing performed decades ... Dry hillslope underlain by ice rich permafrost and now covered with native grasses and managed as a rustic golf course. The land clearing performed decades ago has caused permafrost thawing, surface subsidence, and development of thermokarst mounds or baidjarahks. No foreign fill materials, pesticides or fertilizers have been used, and the area is not irrigated. The area outside the flux footprint is second growth deciduous forest with similar soil conditions.

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-YNS, 64.8939, -147.6374.
