| Description: | The Delta Junction 1987 Burn site is located near Delta Junction, just to the north of the Alaska Range in interior Alaska. All three Delta Junction sites ... The Delta Junction 1987 Burn site is located near Delta Junction, just to the north of the Alaska Range in interior Alaska. All three Delta Junction sites are within a 15-km radius of one another. Composed of a combination of alluvial outwashes, floodplains, and low terraces dissected by glacial streams originating in the nearby Alaska Range. The Granite Creek fire burned ~20,000 ha of black spruce (Picea mariana) during 1987. Approximately half of the dead boles remained upright in 2004, while the other half had fallen over or had become entangled with other boles. See MoreShow Less |

The research objectives of the Delta Junction 1920 Control, 1987 Burn, and 1999 Burn sites are to characterize changes in the annual surface energy budget caused by fire-induced disturbance and to improve the understanding of global change in terrestrial ecosystems. The use of remote sensing data, atmospheric trace gas observations, field measurements, and models in new ways to study feedbacks between terrestrial ecosystems and climate. These three tower sites were selected in ecosystems that were part of a fire chronosequence and in various stages of recovery following fires that occurred in ~1920, 1987, and 1999.

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-Bn2, 63.9198, -145.3782.
