| Abstract: | Water quality simulation models such as the Soil andWater Assessment Tool (SWAT) and
Agricultural Policy EXtender (APEX) are widely used in the US. These models require large amounts
of spatial and tabular data to simulate the natural world. Accurate and seamless daily climatic data
are critical for accurate depiction of the hydrologic cycle, yet these data are among the most difficult
to obtain and process. In this paper we describe the development of a national (US) database of
preprocessed climate data derived from monitoring stations applicable to USGS 12-digit watersheds.
Various sources and processing methods are explored and discussed. A relatively simple method
was employed to choose representative stations for each of the 83,000 12-digit watersheds in the
continental US. Fully processed climate data resulting from this research were published online to
facilitate other SWAT and APEX modeling efforts in the US. |
