Technical Abstract: Dr. E. Raymond Hunt, Jr., USDA/ARS, will be presenting recent research on the use of AWiFS shortwave infrared band (Band 5: 1.50 to 1.70 µm wavelength) for the prediction of vegetation water content. Data from many different land cover types show there is a relationship between the normalized difference of Band 4 (near-infrared: 0.77 to 0.86 µm wavelength) and Band 5 and total water content of the canopy. This information needs to be combined with other data to estimate vegetation dryness for predicting irrigation needs and wildfire potential.
