The majority of these data were processed from instrument measurements taken
aboard the Nimbus-4 and Nimbus-7 spacecrafts from the 1970's throughout the
1980's. Primary among these are the Nimbus-4 BUV ozone, Nimbus-7 SBUV and
TOMS ozone, Nimbus-7 LIMS stratospheric trace species, and Nimbus-4 IRIS
radiance data. Others include trace species data and atmospheric emission
spectra from the Shuttle-borne SpaceLab 3 as well as ozone profile and IR/UV
radiance data from the SME platform. Some of these data arealready available from the Goddard
GES DISC via FTP(some are still on tapes and would be made available on-line at user's rerequest. These data are available according to the tables that follow.
Ozone was monitored by two similar instruments; the Backscatter
Ultraviolet Spectrometer (BUV) and the Solar Backscatter Spectrometer
(SBUV).The BUV was mounted on the Nimbus-4 satellite and collected
data from 1970-04-10 to 1977-06-05.The SBUV was mounted on the Nimbus-7
satellite and collected data from 1979-01-21 until 1987-01-24.The data
from both instruments were processed using the same algorithm.
The data are available in three formats, depending on desired level
of processing.
- High-Density (HDSBUV or HDBUV) - Full resolution data with complete auxiliary information
- Compressed Ozone (CPOZ) - Full resolution data with selected auxiliary information
- Zonal Mean Tape (ZMT) - Zonal mean data only

The Infrared Interferometer Spectrometer (IRIS) on Nimbus 3 and 4 measured
thermal emission of the Earth and its atmosphere in the spectral range of
5 to 20 micrometers, with nominal spectral resolutions of 5 and 1.4 cm**-1,
respectively.Interferograms were Fourier transformed into spectra.

TheAtmosphericTraceMolecule Spectroscopy (ATMOS) experiment was
flown on the Space Shuttle STS-51B as part of the Spacelab-3 laboratory
todemonstratethecapabilitytomonitor environmentalquality
bysurveying theatmospherefortrace constituentsandbyidentifying
theirsources, flow patterns, and decaymechanisms.The ATMOS experiment
objectivewasto determine concentration profiles for a large number of
stratosphericspecies for altitudes from20 to 80 km, with a vertical
resolution of 2 km. The ATMOS instrument viewed the sun through the
stratosphere and measured the spectral absorption of solar energy. Each
data-taking run was initiated before the sun emerged from or disappeared
behind the earth.Data from the instrument for these sunrise and sunset limb
encounters were interferograms that were processed on the ground to
provide absorption spectra.ATMOS also collected IR solar spectral data
on the molecular processes occuring near the Sun's surface and on the
physical structure and composition of the Sun's chromosphere and
photosphere. The instrument was a continuous-scanning Fourier spectrometer
that operated in the 2- to 16-micrometerwavelengthregion and generated
one interferogram eachsecond, with a spectral resolution of 0.01 (1/cm).
The ATMOS instrument is part of NASA/JPL's long-term atmospheric
measurement program. ATMOS was also flown on ATLAS-1 and ATLAS-2 as
part of NASA's Mission to Planet Earth Program (MTPE). ATMOS will be
flown on subsequent ATLAS shuttle missions.

Infrared radiances from the LIMS instrument, mounted on the Nimbus-7 satellite,
were stored on a Radiance Archive Tape (RAT).RAT data was used to derive
a series of products:
- LIMS Inverted Profile Archival Tape (LAIPAT)
- Radiances (from RAT) are used to derive
daily inverted profiles of temperature, and mixing ratios of ozone,
water vapor, nitric acid, and nitrogen dioxide.Profiles are geolocated.
- LIMS Map Archival Tape (LAMAT)
- LAIPAT data is processed to create daily
maps 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)
data.
- LIMS Stacked Map Archival Tape (LASMAT)
- LASMAT data are monthly and seasonal means of LAMAT data.

The Solar Backscatter Ultraviolet (SBUV) on Nimbus 7 mainly measures albedos
at 12 selected wavelengths in the UV spectrum for the purpose of deriving
atmospheric ozone.In the spectral scan mode, however, it measures solar
irradiances and earth radiances from 160 to 400 nm in 0.2-nm steps, with a
1.1-nm half-width triangular bandpass.Solar measurements were made once
a day (three scans), at the northern terminator of one orbit.Earth
measurments were made once every 24 days for the entire day, in place of
the step scan measurements for ozone determination.
