Global monthly gross primary productivity (GPP) of biomass for December 2016.
Location of wetland sites in the Mississippi River Delta where biomass measurements were collected in the Pre-Delta-X Spring and Fall 2015 Campaigns.
Searching for the term remote sensing and words related to invasive species (invasive, nonnative, exotic, or nonindigenous) in Google Scholar reveals an increasing number of publications each year using these terms.
A new Earthdata article describes how researchers are using remote sensing to map invasive species.
Vegetation point-intercept (VPI) any-hit cover metric data were combined with Landsat imagery to develop fractional maps of any-hit cover for four aggregated plant functional types (PFTs); shrubs bryophytes, lichen, and herbs for the upland tundra area of the Y-K Delta, Alaska. VPI data were collected from plots in areas burned in 1971, 1985, 2005, and 2015.
Ecological field data and maps of vegetation cover spanning gradients of fire history in upland tundra are available from the Arctic-Boreal Vulnerability Experiment (ABoVE).
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.
Annual estimates of fractional land use and cover patterns are available for the period 2015 to 2100.
GEDI data will help further refine our understanding of the carbon cycle and atmospheric concentrations of carbon dioxide (CO2).
Level 1 and 2 high-resolution, laser altimetry data from the Global Ecosystem Dynamics Investigation (GEDI) are now available from the LP DAAC.
Solar-Induced Fluorescence derived along ERS-2 GOME orbital tracks on 1 July 1995.
Global estimates of solar-induced fluorescence (SIF) of chlorophyll from 1995 to 2003 are 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.
