ISCAT 1998 Field Season South Pole Observations of Photolytic Reaction Rate Coefficints
Listed in NASA Earthdata CMR
The 1998 - 1999 ISCAT South Pole observational data are available on one CD-ROM.
Description
The aerosol data, trace gas data, and photolyitc rate coefficients are separated into three directories: Aerosol, TraceGases, and j-values. In the j-values directory, there are 24 data files and one readme.txt file describing the data format, measurement techniques, precisions and accuracies, and detection limits.
The data files include downwelling and total j-values for 10 photolysis reactions. Detailed description of project ISCAT can be found in the special section in GRL October 1, 2000. The ISCAT data CD is available by contacting Douglas D. Davis: Dr.

The UV sensor extended 1 - 2 m from the building and was about 10 meter above the snow surface. The reported j-values and source of the cross sections and quantum yields are as the following. - J[O3 -> O2 + O(1D)] (xs:WMO85+Molina/qy:Talukdar98) - J[NO2 -> NO + O(3P)] (xs:JPL94/qy:Gardiner) - J[H2O2 -> 2 OH] (xs:JPL97/qy:1) - J[HNO2 -> OH + NO] (xs:JPL97/qy:1) - J[HNO3 -> OH + NO2] (xs:Burkholder93/qy:1) - J[CH2O -> H + HCO] (xs:NCAR/qy:Madronich91) - J[CH2O -> H2 + CO] (xs:NCAR/qy:Madronich91) - J[CH3COCH3] (xs:Martinez91/qy:McKeen97) - J[CH3OOH -> CH3O + OH] (xs:IUPAC97/qy:1) - J[CH3ONO2 -> CH3O+NO2] (xs:Talukdar97/qy:1) - J[PAN + hv -> products] (xs:Talukdar95/qy:1)
