UARS On-Line Data Access

The goal of the Upper Atmosphere Research Satellite (UARS) is to understand the chemistry, dynamics, and energy balance above the troposphere, as well as the coupling between these processes and between regions of the atmosphere. The UARS platform provides near global (-80° to +80°), simultaneous, coordinated measurements of atmospheric internal structure (trace constituents, physical dynamics, radiative emission, thermal structure, density) and measurements of the external influences acting upon the upper atmosphere (solar radiation, tropospheric conditions, electric fields).

The UARS data are grouped by "Data Product", and the link in the its column below will take you to a page listing available data products.

Data Product	Description	Begin Date	End Date
CLAES	The Cryogenic Limb Array Etalon Spectrometer measures concentrations of members of the nitrogen and chlorine families, ozone, water vapor and methane, as well as aerosol and temperature profiles.	1991-10-25 00:00:45	1993-05-05 17:33:24
Correlative	Access to correlative data products created for the UARS project. These data consist of temperature, height, moisture, and wind field profiles from model assimilations, and can be used for evaluating the various UARS instrument data products.	1991-09-12 00:00:00	2001-09-30 23:59:59
HALOE	The HALogen Occutlation Experiment measures concentrations of HCl and HF, methane, ozone, water vapor, and members of the nitrogen family, as well as temperature and aerosol extinction profiles by sensing atmospheric infrared absorptions from occulted sunlight.	1991-10-11 07:14:50	2005-11-21 23:36:58
HRDI	The High Resolution Doppler Imager measures velocities of wind fields from the Doppler shifts of molecular oxygen absorption lines (below 45 km, daytime only) and atomic emission lines (above 60 km, day & night).	1991-11-06 02:08:35	1999-01-30 11:53:07
ISAMS	The Improved Stratospheric And Mesospheric Sounder measures the concentrations of nitrogen chemical species ozone, water vapor, methane, and carbon monoxide, as well as temperature and aerosol profiles.	1991-09-26 13:07:35	1992-07-29 09:55:12
MLS	The Microwave Limb Sounder measures microwave emissions of chlorine monoxide, methyl cyanide, water vapor, nitric acid, sulfur dioxide and ozone. MLS also measures upper tropospheric relative humidity, temperature and geopotential height profiles.	1991-09-18 00:00:30	1999-07-28 00:00:20
PEM	The Particle Environment Monitor measures the type, amount, energy, and distribution of particles (electrons, protons, and x-rays) injected into the Earth's thermosphere, mesosphere, and stratosphere.	1991-09-15 13:57:16	2005-08-23 15:10:49
SOLSTICE	The SOLar STellar Irradiance Comparison Experiment measures solar ultraviolet radiation in the spectral range from 119 to 420 nm.	1991-10-03 00:00:00	1999-12-31 23:59:59
SUSIM	The Solar Ultraviolet Spectral Irradiance Monitor measures ultraviolet radiation in the spectral range between 115 and 411 nm.	1991-10-12 00:00:00	2005-08-01 23:59:59
WINDII	The WIND Imaging Interferometer measures the velocity of upper atmospheric wind fields, through the measurement of Doppler shifts of molecular and atomic emission lines, and temperature above 80 km.	1991-11-04 01:44:58	1997-08-19 22:00:19
