Abstract

WOFOST (WOrld FOod STudies) is a well-known, widely applied simulation model to analyze quantitatively the growth and production annual field crops that was originally developed for crops in European countries. It is the base model for Monitoring Agricultural ResourceS (MARS) Crop Growth Monitoring System (CGMS) in operational use for yield estimation in European Union. The model is of great potential in providing effective modeling of crops in the United States. The first step to adopt the model to be fit for applications to crop modeling in the US is to provide required parameters at any region and any time in the United States. In this study, several data sources have been identified and enabled to be readily fed into the models through standard, open, automatic, Web-based, online geospatial Web services. These Web services have the flexibility of accessing, re-processing, and customization to the models at different levels-from regional (i.e. counties, agricultural statistic districts) modeling to point (i.e. pixel) modeling because of their spatiotemporal capabilities. Three major data sources and parameters for WOFOST model are meteorological data, crop data, and soil data. Soil data are accessed and customized through standard Web Feature Service (WFS) request to the online services of Soil Survey Geographic Database (SSURGO). Crop data are retrieved from Web Coverage Service (WCS) from CropScape that serves Cropland Data Layer (CDL). Assimilated data from ground observations provide meteorological observations. Meteorological observations are retrieved online through public service application programming interface (API) of DayMet that provide gridded estimates of daily weather parameters for North America, including daily continuous surfaces of minimum and maximum temperature, precipitation occurrence and amount, humidity, shortwave radiation, snow water equivalent, and day length. Workflow is enabled to support the on-demand customization and live feeding to WOFOST modeling. The services enable the parameterization process in WOFOST modeling.
