Vegetation Outlook (VegOut)
The Vegetation Outlook (VegOut) is a new experimental tool that provides future outlooks of general vegetation conditions. VegOut integrates climate information and satellite-based observations of current vegetation conditions with oceanic index data and other biophysical information about the environment (i.e., land cover type, irrigation status, soils, and ecological setting) to produce 1-km2 resolution maps of projected general vegetation conditions into the future. The VegOut utilizes the inherent time-lag relationship between climate and vegetation response and considers teleconnections between the ocean and climate patterns over the continental U.S. Current research is focusing on the development of 2-, 4-, and 6-week Vegetation Outlooks in the U.S. Great Plains. Alternative modeling techniques and new inputs into the current VegOut models are also being investigated in an effort to provide more accurate predictions of future vegetation conditions. Expansion of VegOut to other parts of the U.S. is also planned. Interests on the VegOut model and products in other countries are also observed.
Figure. (a) Observed seasonal greenness (SSG) for June 29, 2009; (b), (c), and (d) are 2-, 4-, and 6-week outlooks; (e), (f), and (g) are observed SSG for July 13, July 27, and August 10 that correspond to the 2-, 4-, 6-week outlooks, respectively; and (h), (i), and (j) show the difference between the predicted and observed greenness for the corresponding 2-, 4-, and 6-week outlooks, respectively.
