The atmospheric infrared sounder (AIRS) is one of six instruments flying on board NASA's Aqua satellite, launched on May 4, 2002. The instrument is designed to support climate research and improve weather forecasting .

2024年12月19日 · Aqua carries three sounding instruments: the Atmospheric Infrared Sounder (AIRS), the Advanced Microwave Sounding Unit (AMSU), and the Humidity Sounder for Brazil (HSB). AIRS observes over 2378 spectral bands with a frequency range of 19 - 80 GHz.

An atmospheric sounder measures how the physical properties of a column of air vary with altitude. The measurement as a function of altitude is sometimes called a “profile”, a “sounding”, or a “retrieval”. The term "sounder" refers to measuring how the temperature and salinity are similarly measured in the ocean using sound waves.

The GeoXO Sounder (GXS) will provide real-time information about the vertical distribution of atmospheric moisture, winds, and temperature. A sounder is a camera-like device whose detector is sensitive to numerous fine-scale ranges of infrared wavelengths, or bands.

2002年5月4日 · 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.

2023年7月21日 · The Advanced Technology Microwave Sounder (ATMS) operates in conjunction with the CrIS to profile atmospheric temperature and moisture. Higher (spatial, temporal and spectral) resolution and more accurate sounding data from CrIS and ATMS will support continuing advances in data assimilation systems and NWP models to improve short- to medium ...

The Cross-track Infrared Sounder (CrIS) is the first in a series of advanced operational sounders that will provide more accurate, detailed atmospheric temperature and moisture observations for weather and climate applications. This information will help significantly improve climate prediction and both short-term weather "nowcasting" and ...

Launched in 2002, the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA’s Aqua satellite provides 3D measurements of temperature, water vapor, trace gases, and surface and cloud properties through the atmospheric column.

The Atmospheric Infra-Red Sounder (AIRS) instrument is a hyperspectral – measures a large number of wavelengths over a two-dimensional field of view, creating a ‘data cube’ infrared – observes in the wavelengths redder than the eye can see
