Weather Solutions for Global Governments and Organizations
Governments and professional organizations worldwide need to access global data from the macro- to the micro-scale for a wide variety of advanced, automated decision support systems.
WDT has developed a turnkey mesoscale numerical weather prediction system that can be customized to a client’s particular operational needs to provide detailed guidance for meteorologists and as input to other automated decision support systems.
WDT’s NWP Experience and Capabilities
WDT has a team of NWP experts with decades of combined experience developing and/or using various NWP systems for operational weather forecasting applications, ranging from the global scale to the microscale. WRF is the primary mesoscale NWP system used by WDT for the past few years. Currently, WDT produces over 300 different WRF forecast simulations per day in its world class Oklahoma City data center, with output being provided in standard WMO formats to a variety of customers as well as being used to improve a host of other meteorological products and services.
MAPSS Details
MAPSS is the built around the WRF model, which represents leading edge technology in the field of NWP. The WRF model is now the primary regional forecast model in the U. S., and is being used by many other operational and research institutions around the world. The numerical methods used within WRF are significantly improved both in accuracy and efficiency compared previous mesoscale models such as MM5, ARPS, and RAMS.
Although the WRF model is scientifically advanced and its open source nature ensures community use and contributions, it does not include the necessary components to allow users to easily configure it for robust and efficient operations. MAPSS provides a software wrapper around the key components of WRF to ensure reliable execution, monitoring, and data delivery.
Output Products
Data products from the system are produced in WMO GRIB-2 format. To minimize latency, WDT’s MAPSS utilizes concurrent post-processing, such that products become available as the model progresses forward in time rather than waiting for the entire forecast run to complete. Additionally, the system includes automated graphical product generation in PNG format, suitable for basic web page viewing, and the WRF Management Portal includes a viewer to display these images.
The WDT PostWRF program performs grid destaggering, vertical interpolation, and diagnostic computations to produce the following sets of output products in GRIB-2 format:
- Surface products
- Products on standard pressure levels
- Aviation products
