Whole atmosphere modeling: Connecting terrestrial and space weather
(American Geophysical Union, 2011-11-12)
At the turn of the century R. G. Roble advanced an ambitious program of developing an atmospheric general circulation model (GCM) extending from the surface to the exosphere. He outlined several areas of research and ...
Using a regional numerical weather prediction model for GNSS positioning over Brazil
(2016-10-01)
The global navigation satellite system (GNSS) can provide centimeter positioning accuracy at low costs. However, in order to obtain the desired high accuracy, it is necessary to use high-quality atmospheric models. We focus ...

Sensitivity of WRF short-term forecasts to different soil moisture initializations from the GLDAS database over South America in March 2009
(Elsevier Science Inc, 2016-01)
In Numerical Weather Prediction models it is essential to properly describe both the atmosphere and the surface initial conditions. With respect to the last, a major issue is the difficulty to attain a correct representation ...
