Instruments

The following instruments are supported by the TROPESS project currently.

AIRS

Launched May 4, 2002

The Atmospheric Infra-Red Sounder (AIRS) instrument was launched into Earth orbit on May 4, 2002 aboard NASA’s Aqua satellite.

The AIRS instrument is a hyper-spectral infrared atmospheric sounder. It measures a large number of wavelengths, over a two-dimensional field of view, in the infrared wavelengths.

For more information see Atmospheric Infra-Red Sounder (AIRS).

CrIS (JPSS-1 / NOAA-20)

Launched November 18, 2017

This is a second instance of the Cross-track Infrared Sounder (CrIS) instrument launched aboard NOAA-20 / JPSS-1 satellite. NOAA-20 was launched on November 18, 2017.

The Joint Polar Satellite System (JPSS) includes five satellites: NOAA/NASA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite, NOAA-20 (JPSS-1), NOAA-21 (JPSS-2), and the upcoming JPSS-3 and JPSS-4 satellites.

For more information see Cross-track Infrared Sounder (CrIS).

CrIS (Suomi NPP)

Launched October 28, 2011

The Cross-track Infrared Sounder (CrIS) is one of the instruments currently flying on the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite which was launched on October 28, 2011. CrIS measures the infrared spectrum emitted from the top of the atmosphere. It is functionally similar to AIRS.

For more information see Cross-track Infrared Sounder (CrIS).

OMI

Launched July 15, 2004

The Ozone Monitoring Instrument (OMI) flies on the NASA’s Aura satellite, launched into Earth orbit on July 15, 2004.

The OMI instrument is a nadir viewing imaging spectrograph that measures the solar radiation backscattered by the Earth’s atmosphere and surface over the entire wavelength range from 270 to 500 nm with a spectral resolution of about 0.5 nm.
