IR Emissivity Data on Vegetation at the MODIS Emissivity Library

Data available includes 24 sample of vegetation ranging from the Leaf of the Algerian Ivy (Hedera canariensis algerian ivy) to the Leaf of Sweet Gum tree (liquidamber styreciflua), one sample of bark of the Eucalyptus tree and three sample of dry grass.

Commentary of the site data reads:

"Vegetation Green vegetation typically has a very high emissivity because it is structured and contains water. Senescent (dry) vegetation has a more variable emissivity, especially in the 3 to 5 µm region, which depends on the type and structure of the cover type, the dryness, and so forth."
