ForWarn improves near-real-time data visualization
ForWarn has always allowed users to view historical 8-day NDVI data, and this capability provides important long-term context for understanding disturbance impacts, recovery, inherent differences among vegetation types and seasonal phenology. Due to processing requirements, these historical MODIS data are posted only after a year has passed. Meanwhile, ForWarn's change maps rely on current images that are less well processed from expedited (eMODIS) data for near real time availability. You can now view this eMODIS data stream along with the historical time series across the US using ForWarn's graph NDVI tool, located on the viewer's toolbar.
