WDT utilizes the premier weather model, Weather Research and Forecasting Model (WRF). Forecasts are generated on a 28-km grid in two modes: 72-hour forecasts updated every 6 hours over CONUS, and 9-hour forecasts updated hourly over North America. The latter are intended to provide conditional precipitation type for MAPLE forecasts.

In addition, WDT utilizes the GFS model for other global applications.

Site-specific modeling
WDT can host your real-time or retrospective mesoscale forecast. We also provide custom systems that run on your hardware with your data feeds. (For remote, real-time operations, WDT recommends IPS MeteoStar for data feeds.)

Key Numerical Modeling Projects

• WDT built and implemented a WRF ADAS NWP System (nested in GFS) for the government of Paraguay. WDT worked with CAPS to build an ADAS-to-WRF converter for this project. LEADS is used for the data ingest (Carpenter et al., 2004).
• WDT built and delivered to Meteorlogix an ARPS ADAS system for use locally by television stations (Carpenter and Bassett, 2001).
• WDT and CAPS built and implemented a large ARPS ADAS solution for Williams Energy Marketing and Trading.
• WDT ported the GFS and GDAS to a 300-node Linux cluster for Williams Energy Marketing and Trading and developed a system for running it early.
• WDT has implemented in-house an WRF ADAS solution and runs it operationally 24/7/365. Customers include: IPS MeteoStar, AccuWeather, Meteorlogix, Weather Central, WeatherTAP, Jeppesen, NEG-Micon USA, Noble Drilling, Western Farmers Electric Cooperative, National Rural Telecommunications Cooperative, and over 100 Electric Cooperatives.
