Data from AIRS
Launched aboard the NASA Earth Observing System satellite called "Aqua" in 2002, the Atmospheric Infrared Sounder (AIRS) instrument suite constitutes an innovative spaceborne atmospheric sounding system comprised of the AIRS hyperspectral infrared instrument and two multichannel microwave instruments the Advanced Microwave Sounding Unit (AMSU-A) and the Humidity Sounder for Brazil (HSB). Together these instruments observe global water and energy cycles, climate variation and trends, and the response of the climate system to increased greenhouse gases.
AIRS retrieved data products provide a daily global view of the three-dimensional physical state of the atmosphere (air temperature, water vapor, clouds) and the distribution of trace gas constituents (ozone, carbon monoxide, carbon dioxide and methane).
Operational Level 1B, Level 2 and Level 3 data products from the AIRS, AMSU, and HSB instruments are freely available at no charge for use by the general public.
Level 1B data product: geolocated, calibrated observed microwave, infrared and visible/near-infrared radiances, and quality assessment data
Level 2 data product: geolocated, calibrated cloud-cleared radiances and 2-dimensional and 3-dimensional retrieved geophysical quantities
Level 3 data product: retrieved geophysical quantities averaged and binned into 1°x1° grid cells (daily, 8-day, monthly)
Products of Earth's atmosphere and Surface
AIRS retrieved geophysical quantities provide the state of the atmospheric column (temperature, water vapor, cloud properties and trace gases) on a fixed pressure grid as well as surface properties and indicators for dust and sulphur dioxide.
