Air temperature by altitude, detailed (Aqua)

TROPESS AIRS-Aqua L2 Atmospheric Temperature for Forward Stream, Standard Product V1 (TRPSDL2TATMAIRSFS) at GES DISC
atmosphere NASA GES_DISC Level 2 active
In plain English

What it measures. Shows air temperature at different heights through the atmosphere, from the surface up high, with uncertainty estimates for each level.

How it's made. Derived from the AIRS instrument on NASA's Aqua satellite using the TROPESS estimation method, delivered as daily files of vertical temperature profiles.

How & where you'd use it. Useful for weather and climate research, understanding how temperature varies with altitude, and improving atmospheric models.

Official description

The TROPESS AIRS-Aqua L2 Atmospheric Temperature for Forward Stream, Standard Product contains the vertical distribution of the retrieved atmospheric state of atmospheric temperature (TATM), formal uncertainties, and diagnostic information measured by the AIRS instrument on the EOS Aqua satellite. The forward stream standard product is global for the time period from 2021-02-01 to present. The NASA TRopospheric Ozone and Precursors from Earth System Sounding (TROPESS) project, uses an optimal estimation algorithm, known as the MUlti-SpEctra, MUlti-SpEcies, Multi-SEnsors (MUSES). The data files are written in the netCDF version 4 file format, and each file contains one day of data. The data have a spatial resolution of 14 km (AIRS nadir FOV), and are reported at 31 vertical levels from the surface to 0.1 hPa. The principal investigator for the TROPESS project is Kevin W. Bowman.
