Global OH distribution derived from general circulation model fields of ozone and water vapor

The variability of OH computed with a photochemical steady state model from general circulation model fields of ozone and water vapor is examined. Multivariate regression analysis is used to obtain values of parametric coefficients for the variables upon which the OH field principally depends, and conclusions are drawn about the longitudinal phase relations between these variables for various pressure levels. 21 references, 8 figures, 6 tables.
