CEOS Instrument: Improved Limb Atmospheric Spectrometer
| Instrument: | ILAS |
| Agencies: | MOE (Japan) [Primary] |
| JAXA | |
| Mission: | ADEOS |
| Status: | No longer operational |
| Type: | Limb-scanning IR spectrometer |
| Description: | Measures minor trace gas species at high latitudes, in the altitude range 10 - 60 km (O3, CH4, NO2, N2O, H2O, CFC11, HNO3, CIONO2, N2O5, aerosols, temparature, pressure) |
| Spatial Resolution: | 700 m |
| Swath Width: | 1400km |
| Wavebands: | NIR (~0.75 ?m - ~1.3 ?m) |
| Technology: | Limb-scanning IR spectrometer |
| Description: | Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.01 % required for atmospheric chemistry. Designed to provide high vertical resolution in the upper troposphere and above by scanning the Earth’s limb. Many thousands of channels. Spatial resolution typically 1-3 km vertical, 300-500 km horizontal. Applicable only in LEO. |
