Summary:

This study focuses on the estimation of two parameters of the Penman-Monteith equation, namely, the aerodynamic and the surface resistances, for a raised bog in the Irish Midlands. Data were provided by an automatic weather station which was installed in the middle of the bog and several other types of data were also collected. The typical zero-plane displacement d = 0 and the roughness length z0 = 0.021 m were estimated from average hourly wind speed profiles. The surface resistance was found to vary between 30 and 125 sm-1. A predictive model of surface resistance versus time was only partially successful.
