任务简介
对流上升气流调查(INCUS)是一项由科罗拉多州立大学主导的NASA地球科学任务,旨在研究热带风暴的行为,以便在天气和气候模型中更好地表征这些风暴。该任务由3颗紧密协同飞行的SmallSat组成,研究对流风暴、强降水和云为何恰好在其形成的时间和地点发生。 每颗卫星将配备高频降水雷达,用于观测对流云深度和强度的快速变化。其中1颗卫星还将携带微波辐射计,以提供雷达观测到的更大尺度天气的空间信息。通过紧密编队飞行,卫星利用观测时间的微小差异,采用新颖的时间差分方法来估算对流质量的垂直输送。

The Investigation of Convective Updrafts (INCUS) is a NASA Earth science mission led by Colorado State University that will investigate the behavior of tropical storms in order to better represent these storms in weather and climate models. It consists of 3 SmallSats flying in tight coordination to study why convective storms, heavy precipitation, and clouds occur exactly when and where they form. Each satellite will have a high frequency precipitation radar that observes rapid changes in convective cloud depth and intensities. 1 of the 3 satellites also will carry a microwave radiometer to provide the spatial content of the larger scale weather observed by the radars. By flying so closely together, the satellites will use the slight differences in when they make observations to apply a novel time-differencing approach to estimate the vertical transport of convective mass.
