CEOS EO HANDBOOK – INSTRUMENT SUMMARY - UV/Vis Near IR Wide Imaging Spectrometer (Geo-Cape) -
Full Name UV/Vis Near IR Wide Imaging Spectrometer (Geo-Cape) Status No longer considered
Instrument Agencies NASA Maturity High Heritage - Non-Operational
Instrument Type Imaging multi-spectral radiometers (vis/IR) Geometry Nadir-viewing
Instrument Technology High-resolution nadir-scanning SW spectrometer Sampling Imaging
Data Access Open Access Data Format
Measurements and Applications Measures natural and human-produced gases and aerosols in the atmosphere, including those that react in sunlight to form polluting low-level ozone.
Resolution Summary 7 km spatial resolution, single layer vertical resolution, 0.9 nm spectral resolution
[Best Resolution: 7000m]
Swath Summary typically uses 2D data array with 1-D north to south in space (7 km wide) and 1D for (oversampled) spectral intervals/bins. The spatial domain is mechanically scanned for east to west to cover a continental domain (either north or south America).
Accuracy Summary ozone precision: 1.3 x 10^16 cm^(-2); NO2 precision: 5 x 10^14 cm^(-2)
Waveband Summary 315 - 600 nm
UV (~0.01 µm - ~0.40 µm)
VIS (~0.40 µm - ~0.75 µm)
NIR (~0.75 µm - ~1.3 µm)
