Measured spacecraft dynamic effects on atmospheric science instruments

Abstract

Three case studies showing the impact of remote-sensing spacecraft dynamic response on science measurements are discussed. In the first case, correlation of independent atmospheric meridional wind measurements demonstrate that excessive vibration results in wind measurement disagreement. In the second case, solar array disturbances produce a spacecraft response signature on radiometer measurements, demonstrating that spacecraft dynamic response could impact measurements. In the final case, correlation of an instrument's fine sun-sensor data and CO2 measurements demonstrate the effect of temporal and spatial sampling resolution and active pointing control on science measurements.
