Data Availability Name Description Objective Dates
DownloadableMODIS DUR Yearly Mean and STDYearly mean, standard deviation of the yearly mean, and long-term mean (2003-present) for MODIS DUR (duration of the growing season).These data are used in the Vermont Forest Indicators Dashboard, available at uvm.edu/femc/indicators/vt, to quantify annual changes in the duration of the growing season.2001-01-01 (ongoing)
DownloadableMODIS DUR Yearly Mean and STDYearly mean, standard deviation of the yearly mean, and long-term mean (2003-present) for MODIS DUR (duration of the growing season). This dataset includes growing season estimates for New Hampshire, New York, and Vermont.The length of the growing season varies from year to year based on spring and fall temperatures. Increases in the length of growing season can benefit some species by providing extra time for growth and reproduction, but can cause harm to others by increasing heat, water, and metabolic stress1. Ideally, a healthy forest would have a growing season that remains relatively consistent.2003-01-01 (ongoing)
DownloadableMODIS TIN Yearly Mean and STDYearly mean, standard deviation of yearly mean, and long-term mean (2003-present) of MODIS TIN (peak canopy density).These data are used in the Vermont Forest Indicators Dashboard, available at uvm.edu/femc/indicators/vt, to quantify annual changes in the density (or 'greenness') of the tree canopy.2001-01-01 (ongoing)
DownloadableMODIS TIN Yearly Mean and STDYearly mean, standard deviation of yearly mean, and long-term mean (2003-present) of MODIS TIN (peak canopy density). This data covers canopy density for New Hampshire, New York, and Vermont.Canopy density or ‘greenness’ is estimated using data collected by the MODIS1 satellite mission, and represents the thickness of the forest foliage. MODIS captures bimonthly imagery of Vermont’s forests which are then aggregated across the full growing season. Canopy reflectance at different wavelengths is used to calculate a normalized difference vegetation index (NDVI), which is an assessment of overall greenness of the forest canopy. 2003-01-01 (ongoing)
