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.
