Description:	This site was established on a 25m freestanding former radio tower at the Forest Service's Rocky Mountain Research Station headquarters in Fort Collins, ... This site was established on a 25m freestanding former radio tower at the Forest Service's Rocky Mountain Research Station headquarters in Fort Collins, CO. The tower is situated next to a parking lot and several one and two story buildings. To the north and west is the campus of Colorado State University, and to the north and east is low density residential development. To the south and east are a busy intersection and rapid transit bus line, and to the south is green space surrounding the City of Fort Collins' Spring Creek Trail. See More Show Less

MODIS NDVI

The time series shows the 16-day Normalized Difference Vegetation Index (NDVI) average from the MOD13Q1 data product.
Use the slider below the time series to zoom in and out.

Includes all pixels that have acceptable quality

To view / download these data and other MOD13Q1 products for this site, visit MODIS/Terra Vegetation Indices.

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 .

GeoNEX 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 .

No GeoNEX data have been received for site US-DUF.
