UARS Cryogenic Limb Array Etalon Spectrometer (CLAES) Level 3AL V009 (UARCL3AL) at GES DISC

Version 009 eng
  • Abstract
    The Cryogenic Limb Array Etalon Spectrometer (CLAES) Level 3AL data product consists of daily, 4 degree increment latitude-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. 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 3AL 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. The following subtypes are available: 1) AERO780 - aerosol extinction at 780 cm-1 [1/km] 2) AERO790 - aerosol extinction at 790 cm-1 [1/km] 3) AERO843 - aerosol extinction at 843 cm-1 [1/km] 4) AERO880 - aerosol extinction at 880 cm-1 [1/km] 5) AERO925 - aerosol extinction at 925 cm-1 [1/km] 6) AERO1257 - aerosol extinction at 1257 cm-1 [1/km] 7) AERO1605 - aerosol extinction at 1605 cm-1 [1/km] 8) AERO1897 - aerosol extinction at 1897 cm-1 [1/km] 9) CF2CL2 - dichlorodifluorocarbon (CFC-12) [vmr] 10) CFCL3 - trichlorofluorocarbon (CFC-11) [vmr] 11) CH4 - methane [vmr] 12) CLONO2 - chlorine nitrate [vmr] 13) H2O - water vapor [vmr] 14) HNO3 - nitric acid [vmr] 15) N2O - nitrous oxide [vmr] 16) N2O5_OTHER - dinitrogen pentoxide (and other) [vmr] 17) NO - nitric oxide [vmr] 18) NO2 - nitrogen dioxide [vmr] 19) O3B9 - ozone at 780 cm-1 (filter 9) [vmr] 20) TEMP - atmospheric temperature [Kelvin] *vmr = volume mixing ratioCLAES 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.
