Sensor Characteristics:
The MAMS is a multispectral scanner which measures reflected
radiation from the earth's surface and clouds in 8 visible/near
infrared channels, and thermal emission in 4 infrared/thermal bands
from the surface, clouds, and atmospheric constituents (primarily water vapor).
Data Products
- Precipitable Water and Skin Temperature (land or sea surface):
derived from with a physical split window algorithm (Jedlovec 1987; Guillory et al 1993; Suggs and
Jedlovec 1986).
- Sea Surface Temperature
- Upper-level Humidity: retrieved with an empirical method similar to Soden and Bretherton (1993).
- Cloud Top Temperature and Height
