GWC’s vision is to leverage technology to increase the global availability of precision weather forecasts while substantially reducing the cost. Our ability to accomplish this builds from DICast weather forecast technology developed by NCAR over the last decade. DICast® is the Dynamic Integrated foreCast system, an NCAR-developed weather forecast software package. It ingests a variety of weather models, statistical data, and observations and produces a point-based weather forecast. The sophisticated algorithms it contains are the basis for the value provided by GWC. LOGICast® is a new gridded version of DICast developed at NCAR; it is used by GWC to power its regional and on-demand services. Both can be customized to provide by-customer proprietary forecasts using additional sensor data and/or numerical forecast models.
