Atmospheric Infrared Sounder

AIRS, the Atmospheric Infrared Sounder on NASA's Aqua satellite, gathers infrared energy emitted from Earth's surface and atmosphere globally, every day. Its data provides 3D measurements of temperature and water vapor through the atmospheric column along with a host of trace gases, surface and cloud properties. AIRS data are used by weather prediction centers around the world to improve their forecasts. They are also used to assess the skill of climate models and in applications ranging from volcanic plume detection to drought forecasting.搭载于美国国家航空航天局Aqua卫星的大气红外探测器（Atmospheric Infrared Sounder，简称AIRS），每日可在全球范围内采集地球表面与大气层辐射的红外能量。其数据可提供沿大气柱的温度、水汽、多种痕量气体、地表及云系属性的三维测量结果。全球各地的气象预报中心均会利用AIRS数据优化预报精度，该数据还可用于评估气候模式的预报性能，以及应用于从火山羽流探测到干旱预报的各类场景中。
