UARS Improved Stratospheric and Mesospheric Sounder (ISAMS) Level 3AL V010 (UARIS3AL) at GES DISC
Listed in NASA Data Portal
The Improved Stratospheric and Mesospheric Sounder (ISAMS) Level 3AL data product consists of daily, 4 degree increment latitude-ordered vertical profiles of temperature and concentrations of O3, H2O, CH4, CO, N2O, N2O5, NO2, and aerosol absorption coefficients.
Description
The insrument measured infrared molecular emmissions in the spectral region from 4.6 to 16.6 microns. ISAMS was flown on NASA's Upper Atmosphere Research Satellite (UARS) and designed to measure the global temperature and composition profiles in the stratosphere and mesosphere.
Limb measurements were made in the altitude range between 15 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 ISAMS Level 3AL data were processed with the version 10 algorithm, except H2O which is version 9.

The ISAMS level 3AL product consists of 10 granules per day. A data granule is one ISAMS 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, ... Each of the 10 ISAMS granules is accompanied by its own additional parameter file, designated as level 3LP. The parameter file, contains the additional ancillary and quality information not found in the 3AL file. The data files are available in a binary record oriented format.
