Real-Time Four Dimensional Data Assimilation (RTFDDA)
RT-FDDA refers to the real-time assimilation of 4DWX weather data. RT-FDDA was developed to provide short-term, high-resolution forecasts using the most recent input data from sensors. This quick turnaround from input to output is essential for creating and delivering timely weather forecasts. RT-FDDA takes input from surface observations, satellite reports, automated weather stations, and other sources. RT-FDDA is deployed and in use at White Sands Missile Range in New Mexico and Yuma Proving Ground in Arizona.
AIRDAT Linux Cluster
AirDat LLc provides three rack-mounted PC clusters for the modeling research and operations. Two parallel RTFDDA systems have been running on a 20-node cluster since December 2004. A 5-node mini-cluster was set up in the spring of 2006 to run a RTFDDA modeling system in support of TAMDAR data quality control. Recently, a third 20-node cluster was purchased and installed at AirDat LLc, which will support various extended TAMDAR-related modeling research and development activities.
