MAMS (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 as follows:
| Channel | Wavelength, µm |
| 1 | (LSBs 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 (6.2 - 6.9) |
| 10 | 3.55 - 3.93 (6.2 - 6.9) |
| 11 | 10.3 - 12.1 |
| 12 | 12.5 - 12.8 |
| Spatial Resolution: | 50 or100 meters from 19.8 km (65,000 ft.) |
| Total Field of View: | 85 degrees |
| IFOV: | 5.0 mrad |
Notes: Channels 9 - 12 are digitized to 10 bits; all others are 8-bit. Blackbody sources are
carried for IR calibration.
