Mapping Monthly Precipitation, Temperature, And Solar Radiation For Ireland With Polynomial Regression And A Digital Elevation Model, Christine L. Goodale, John D. Aber, Scott V. Ollinger

Faculty Publications

A 1 km2 resolution digital elevation model (DEM) of Ireland was constructed and used as the basis for generating digital maps of the climate parameters required to run a model of ecosystem carbon and water cycling. The DEM had mean absolute errors of 30 m or less for most of Ireland. The ecosystem model requires inputs of monthly precipitation, monthly averaged maximum and minimum daily temperature, and monthly averaged daily solar radiation. Long-term (1951 to 1980) averaged monthly data were obtained from sites measuring precipitation (618 sites), temperature (62 sites), and the number of hours of bright sunshine per day …
