Soil Moisture and Tree Measurements at Harvard Forest

Harvard Forest Canopy

Ground-based data collected at the Harvard Forest site was used to validate Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) soil moisture estimates.

Global Solar-Induced Chlorophyll Fluorescence (SIF)

Solar-induced chlorophyll fluorescence.

Predicted spatially contiguous solar-induced chlorophyll fluorescence (SIF) across the United States for August 1 - 16, 2015. Areas of high SIF are in red, and areas of low SIF are in blue. Agricultural areas, like the U.S. Midwestern corn belt, often have a high rate of photosynthetic production which results in high SIF.

High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.

PhenoCam Data Updated

PhenoCam Sites.

Spatial distribution of PhenoCam data across ecological regions of North America. Background map illustrates USA Environmental Protection Agency Level I Ecoregions. Data counts have been aggregated to a spatial resolution of 4°, and the size of each circle corresponds to the number of years of data.

A new version of the PhenoCam vegetation phenology data products is now available.

High Resolution Tree Canopy Cover for MD and DE

Pittsburgh Tree Canopy Cover.

Estimated tree canopy cover (in green) near Pittsburgh, Pennsylvania, for the year 2008.

Statewide tree canopy cover at 1m resolution is now available for Maryland and Delaware.

A new dataset completes four years of post-fire vegetation sampling at burned sites in Canada's Northwest Territories.
