UARS Cryogenic Limb Array Etalon Spectrometer (CLAES) Level 3AT V009 (UARCL3AT) at GES DISC
Listed in NASA Data Portal
The Cryogenic Limb Array Etalon Spectrometer (CLAES) Level 3AT data product consists of daily, 65.536 second interval time-ordered vertical profiles of temperature and concentrations of O3, H2O, CH4, N2O, NO, NO2, N2O5, HNO3, ClONO2, HCl, CF2Cl2 (CFC-12), CFCl3 (CFC-11), and aerosol absorption coefficients.
Description
The instrument measured infrared thermal emissions at wavelengths from 3.5 to 12.7 microns. CLAES was flown on NASA's Upper Atmosphere Research Satellite (UARS) and designed to measure the chemical composition of the stratosphere and mesosphere, and also investigated the depletion of stratospheric ozone and ozone chemistry.
Limb measurements were made in the altitude range between 10 and 60 km at about 2.5 km resolution. Data were collected between latitude 34S and 80N and 80S and 34N, alternating each satellite yaw cycle of about 36 days. The CLAES Level 3AT data were processed with the version 9 algorithm, except H2O which is version 7.

The CLAES level 3AL product consists of 20 granules per day. A data granule is one CLAES species or subtype per day. Data are on the UARS standard pressure levels (in mbars) given by: P(i) = 1000
- 10**(-i/6) for i = 0, 1, 2, ... The data files are available in a binary record oriented format.
