Спутник ФКИ. CloudSat. [Редактировать]

CloudSat — американо-канадский исследовательский спутник, запущенный 28 апреля 2006 с космодрома Ванденберг с помощью ракеты-носителя Дельта-2 7420-10C вместе с другим исследовательским спутником CALIPSO. Спутники запущены в рамках программы НАСА EOS (Earth Observing System (Система наблюдения Земли)) и предназначены для изучения облачного покрова Земли. CloudSat расшифровывается как Cloud Satellite, CALIPSO — Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation.
Оба спутника решают общие задачи: получение трёхмерных изображений облаков и атмосферных аэрозолей; исследование того, как формируются и «развиваются» облака, как они влияют на погоду, климат, качество воздуха и количество осадков. Для этого на CloudSat установлен очень чувствительный радар с миллиметровой длиной волны (который более чем в тысячу раз чувствительнее обычного гидрометеорологического радара), а на CALIPSO — поляризационный лазерный локатор, который позволяет отличить в толще облаков водяной пар и кристаллы льда, жидкие и твёрдые частицы атмосферных аэрозолей. Кроме того, на CALIPSO имеется камера и инфракрасный радиометр. Спутники выведены на солнечно-синхронную круговую орбиту высотой 705 км.
