This allows for a full use of conventional and non-conventional observations, such as the range measurements that are taken at irregular asynoptic times. In data-void regions, the model generates analyses in response to the model physics and fine-scale external forcing, whereas the model is adjusted toward observations where data exists. Each observation is incorporated with proper temporal and spatial weighting functions and the model spreads the observation information to other regions according to the model dynamics. When the system is set up for a specific region, it runs continuously to produce four-dimensional dynamically and physically consistent analyses, which effectively removes the dynamic and diabatic "spin-up" problem. In many cases, short-term forecasts are also produced, initialized from these analyses at a selected cycling interval of 1 - 12 hours based on application needs and availability of computer capacity.Īs of May 1, 2004, fourteen RTFDDA systems have been built to support a variety of DoD missions within and outside the United States for durations from a few days to a few years. The system has also been used/tested for real-time fire weather, urban dispersion and airport operations.Īmong these systems, five are now operating at five Army test ranges and another one is running to support a Pentagon safety project. Since the release of the first operation system at the Dugway Proving Ground in 2000, a lot of work has been continuously carried out to improve the system performance and usability. For example, the nudging weight functions are refined according to weather structures and terrain features. New types of observations are collected and incorporated. A unique data quality control procedure has also been developed. And the model land-surface and PBL physics schemes were modified to more accurately simulate the PBL processes and urban effects. Recently, in cope with the need to quickly deploy the system globally, a convenient but effective Graphic User Interface (GUI) was build for users to start the system at any global location with only a few button-clicks, and view the model output in just a few minutes with graphic media such as a computer terminal or a PDA handhandle. This system is known as the NCAR/ATEC Global Meteorology on Demand (GMOD) system. Finally, in recognition of mesoscale predictability limits, fine-scale ensemble analyses and forecasts may be produced with the GMOD system.
