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%.
