Multispectral Atmospheric Mapping Sensor

The MAMS is a modified Daedalus Scanner flown aboard the ER-2 aircraft. It is designed to study weather related phenomena including storm system structure, cloud-top temperatures, and upper atmospheric water vapor. The scanner retains the eight silicon-detector channels in the visible/near-infrared region found on the Daedalus Thematic Mapper Simulator, with the addition of four channels in the infrared relating to specific atmospheric features. The spectral bands are:

Channel Wavelength, micrometers
1 (Least Sig. Bits for Channels 9-12)
2 0.45 - 0.52
3 0.52 - 0.60
4 0.57 - 0.67
5 0.60 - 0.73
6 0.65 - 0.83
7 0.72 - 0.99
8 0.83 - 1.05
9 3.55 - 3.93 (8.5 - 14.0)
10 3.55 - 3.93 (8.5 - 14.0)
11 10.3 - 12.1
12 12.5 - 12.8

Sensor/Aircraft Parameters:

Spatial Resolution: 100 meters from 19.8 km (65,000 ft.)
Total Field of View: 85 degrees
Instant. Field of View: 5.0 mrad
Notes:
  • Channels 9 - 12 are digitized to 10 bits; all others are 8-bit.
  • Blackbody sources are carried for IR calibration.
