CEOS Instrument: Advanced Land Imager




Instrument:ALI
Agency: NASA
Mission: NMP EO-1
Status:Operational
Type:High resolution optical imager
Description:Measurement of Earth surface reflectance. Will validate new technologies contributing to cost reduction and increased capabilities for future missions. ALI comprises a wide field telescope and multispectral and panchromatic instrument
Spatial Resolution: PAN: 10 m, VNIR and SWIR: 30 m
Swath Width: 37 km
Wavebands: 10 bands: VIS and NIR: 0.480 - 0.690 ?m, 0.433 - 0.453 ?m, 0.450 - 0.515 ?m, 0.525 - 0.605 ?m, 0.630 - 0.690 ?m, 0.775 - 0.805 ?m, 0.845 - 0.890 ?m, 1.200 - 1.300 ?m, SWIR: 1.550 - 1.750 ?m, 2.080 - 2.350 ?m
Technology: High resolution optical imager
Description: Imaging Vis/IR radiometer whose characteristics are stressed towards spatial resolution (typically <30 m). Spectral coverage in bands of Vis and NIR (0.4-1.3 Ám). Number of channels can be small (extreme: one, i.e. panchromatic) or very large (hyperspectral) separated in-field (array detectors) or by a spectrometer, or a combination of both. Channel bandwidths from 0.5 Ám (PAN) to 5 nm (hyperspectral). Applicable only in LEO.
