Negev
|
|
Negev is large desert region in southern Israel and has sand dunes that reach heights of up to 30 meters. Vegetation in the Negev is sparse, and the area receives very little rain annually. The area is characterized by different types of aerosols, including desert dust, maritime, and anthropogenic pollution. Mean annual temperature during summer is ~25 degrees C. The desert is dry (relative humidity ranges from 20 to 50 percent) with clear days having little day-to-day variations [2].
Bright, homogeneous, and remote desert areas within the Negev are used for vicarious absolute calibration of spaceborne sensors, along with in-situ measurements of ground reflectance and atmospheric characteristics during satellite overpasses.
