Estimates of the monthly average values of the components of the surface energy balance were calculated from climatological data observed at the municipal airport near Dayton, OH, using a method proposed by Sellers (1965). Based on these calculations the Great Miami River valley had an annual total net radiation of 52 kilolangleys. Latent heat flux to the air from the surface is 37 kilolangleys yr~' and a sensible heat flux of 15 kilolangleys yr^1. Heat flux into and out of the soil ranged from about 27 langleys day~x in May and June to — 27 langleys day1 in November and December.
