Assimilation of Aircraft Observations in High-Resolution Mesoscale Modeling

Mesoscale Data Assimilation and Prediction with Commercial Aircraft (TAMDAR) Observations

Mesoscale (10 2000 km) meteorological data assimilation and prediction are challenging due to the sparseness of observations, especially in the upper-air atmosphere. In the past 15 years, a number of instruments, e.g. wind profilers, commercial aircraft reports, satellite measurements, and others, have been developed to enhance the upper-air observations. Despite these advances, the present sys...

Improved EM Tactical Applications through UAS-Enhanced High-Resolution Mesoscale Data Assimilation and Modeling

The long-term goal of this project is to develop new and emerging analysis and forecast capabilities via improvements to environmental inputs to electro-magnetic (EM) tactical applications through Unmanned Aerial Systems (UAS) enhanced high-resolution mesoscale data assimilation and modeling. These capabilities will be achieved through the formulation, testing, evaluation, and demonstration of ...

4DWX Mesoscale Modeling and Data Assimilation for NSAP

In FY05, RAL/NSAP modelers continued to work with the U.S. Army Test and Evaluation Command (ATEC), Defense Threat Reduction Agency (DTRA), Defense Advanced Research Project Agency (DARPA), and other public and industrial agencies to study and improve the 4DWX real-time four-dimensional data assimilation and forecast (RTFDDA) system. The work was focused on six areas: (a) transition to the Weat...

Towards high resolution mapping of 3-D mesoscale dynamics from observations

The MyOcean R&D project MESCLA (MEsoSCaLe dynamical Analysis through combined model, satellite and in situ data) was devoted to the high resolution 3-D retrieval of tracer and velocity fields in the oceans, based on the combination of in situ and satellite observations and quasi-geostrophic dynamical models. The retrieval techniques were also tested and compared with the output of a primitive e...
