A Scanning Strategy Optimizedfor Signal-to-Noise Ratio for the Geostationary Carbon Cycle Observatory (GeoCarb) Instrument
by Jeffrey Nivitanont, Sean M. R. Crowell, and Berrien Moore, III
A scanning strategy is proposed for the upcoming GeoCarb instrument that minimizes predicted retrieval errors of CO2 by optimizing signal-to-noise ratio with respect to air mass factor and solar zenith angle. The strategy is generated using a modified greedy algorithm that optimizes over these stationary processes while also considering operational constraints. This method increases the number of soundings with predicted CO2 retrieval error less than 2 ppm by 18–41 %.
