Спутник ФКИ. CALIPSO. [Редактировать]

Американо-французский исследовательский спутник, запущенный 28 апреля 2006 с космодрома Ванденберг с помощью ракеты-носителя Дельта-2 7420-10C вместе с другим исследовательским спутником CloudSat. 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.
Полезная нагрузка:

  • CALIOP (Cloud-Aerosol LIdar with Orthogonal Polarization) - лидар с ортогональной поляризацией для наблюдения облаков и аэрозолей. Разработан в Исследовательском центре имени Лэнгли, изготовлен фирмой Ball Aerospace & Technologies Corp. Прибор предназначен для получения вертикальных профилей упругого рассеяния от облачного слоя в различное время суток, а также для описания распределения в нём водяных паров, аэрозолей и пыли.
  • IIR (Imaging Infared Radiometer) - Видовой инфракрасный радиометр. Разработан Национальным центром космических исследований (CNES) Франция, изготовлен компанией EADS Sodern и предназначен для измерения уровня излучения в различных диапазонах ИК-спектра.
  • WFC (Wide-Field Camera) - Широкоугольная камера высокого разрешения, изготовлена фирмой Ball Aerospace & Technologies Corp.
