Impact/Purpose:
The purpose of this application is to mitigate the amount of work required for retrieving and formatting forecast and historical rainfall precipitation data. The resulting data may be used in hydrology or other modeling efforts to aid in the understanding, prediction, and management of water movement and resources.
Description:
The Weather Data Tool is a command line interface application written in Python that facilitates the acquisition of time series precipitation data from national Forecast and Historical weather data providers; and generates an output file to be consumed by the EPA Storm Water Management Model (SWMM). The application conducts lightweight processing and formatting of the downloaded data to generate an output file containing rainfall precipitation values greater than 0 and conforms to the specified DSI-3240 file format.
