LAC System Trades
IR vs. Visible Spectral Coverage
- IR gives better water vapor and cirrus cloud information at the expense of aerosol information
- InGaAs arrays now can cover 0.5 to 1.7 micron
1.6 vs. 2.5 micron Longwave Cutoff
- Cryogenic cooling not required
Two Module vs. 1 Module Design
- Gain in system flexibility and platform independence compensates for increased mass and additional integration
