Measurements and Applications ARGUS 2000 can be utilized to map the spatial variation of greenhouse gases. Measurement interpretation requires spacecraft attitude information for an accurate geolocation of the spectrometer surface pixel, application of a radiative transfer retrieval algorithm and knowledge of surface cloud conditions and topography. Utilizing a near nadir-pointing configuration, the spectrometer can record infrared radiation emitted from the Earth's surface and atmosphere to space.
Resolution Summary InGaAs detector 1000nm - 1650nm infrared range, 6nm spectral resolution.
[Best Resolution: 1.57m]
Swath Summary The full-width-half-maximum is estimated at 0.15 degrees. At a typical LEO orbital height of 600km, this corresponds to a surface tile of length 1.57km. It is a single pixel detector.
[Max Swath: 2 km]
Accuracy Summary Due to alignment difficulties and variation between test lamps and solar insolation, results are only accurate to approximately 10%.
Waveband Summary 1000 nm – 1650 nm range
SWIR (~1.3 µm - ~3.0 µm)
