Composite AVHRR NDVI and Departure from average
Listed in NASA Earthdata CMR
Since 1997 UMAC has been recieving weekly or biweekly AVHRR composite NDVI and departure from average data for the conterminous United States.
Description
These data are obtained from the EROS Data Center on a weekly basis. The data are then zipped and archived on cd.
Due to the nature of our applications, the data are only acquired during the growing season of the midwestern states, from about the 10th week of the year to the 40th week. The NDVI composite is developed by taking the highest NDVI value perpixel over the composite period. The departure from average is the departure of each pixel in the composite from an average calculated over the period from the beginning of the project in 1989.
