Global Maps of Atmospheric Parameters from NIMBUS-7 LIMS (LAMAT)Entry ID: MR_LN7-3
Abstract: This data set contains daily global maps of 6 atmospheric parameters
(temperature, ozone, nitrogen dioxide, water vapor, nitric acid, and
geopotential height) derived from radiance measurements by the
Nimbus-7 Limb Infrared Monitor of the Stratosphere (LIMS). The daily
maps are given in the form of Fourier coefficients for each parameter
at 18 pressure levels (from 0.05 to 100 mb). Data are ... organized and
averaged into 38 four-degree latitude bands. Data for the daily maps
are interpolated to the two synoptic times (0000 GMT for night and
1200 GMT for day). Also included is the day/night combined (averaged)
The Nimbus-7 LIMS provides nearly global coverage from 64 degrees S to
84 degrees N for all six spectral channels centered at wavelengths
ranging from 6.2 to 15 microns. In general, only temperature and
ozone are mapped at all 18 pressure levels. Maps for the other four
parameters usually stop at altitudes where signal-to-noise values
become inadequate for data reduction. In addition, the analyses at 70
and 100 mb are often missing at tropical latitudes due to clouds
rendering the results unreliable. Each tape contains maps for 23 to 30
days of data. Related LIMS data sets include Radiance Archive Tape
(RAT), Inverted Profile Archival Tape (LAIPAT), and Radiance Profile
Tape (PROFILE-R). The entire 7 months of LAMAT data are stored on a
single 8mm Exabyte tape obtainable from the Goddard Distributed Active
Archive Center (DAAC).
