Concurrent woody and herbaceous vegetation changes between the 1982-1991 and 2004-2013 decades of the Sudano-Sahel region of Africa. (A) Map of vegetation change categories. (B) Chart showing the conceptual position and the relative abundance of each category in a 2-D space.
Vegetation change data spanning the West African Sudano-Sahel region is now available.
Simulated and observed seasonal patterns of canopy SIF (740 nm) for (a, c) absolute SIF and (b, d) normalized canopy SIF for CLM simulation year 2010. Both a satellite SIF product (GOME-2) and the PhotoSpec measurements are included for comparison.
Three related datasets from the Carbon Monitoring System (CMS) program describe year-round photosynthetic activity in a conifer forest.
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.
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 4i, 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.
