| Resumo | The Zenithal Tropospheric Delay (ZTD) is an important error source in the observable involved in the positioning methods using artificial satellites. The humidity convergence zones are characterized by an extensive precipitation band and high nebulosity almost stationary. In South America there are two main convergence zones that has strong influence in the troposphere variability, the ITCZ (Inter Tropical Convergence Zone) and the SACZ (South Atlantic Convergence Zone) zones. While the first is located near the equator, over the Amazonian Region, the second occurs between -18 and -25 of latitude over Brazilian littoral. The physical processes associated with these convergence zones associated with the penetration the cold front from Antarctic pole into the continent present strong impacts in the seasonal variability of wet component (ZWD) of ZTD. In 2010 a new navigation and administration system of the air traffic, denominated CNS-ATM (Communication Navigation Surveillance - Air Traffic Management) should be running operationally in South America. This new system will basically employ the positioning techniques by satellites to the management and air traffic control. However, the efficiency of this new system demands the knowledge of the behavior of the atmosphere, more specifically the characteristic of main factors that influence the oscillation of ZTD components in regional scale. The predictions of ZTD values from Numeric Weather Prediction (NWP), denominated here dynamic modeling, permit assess the temporal and spatial variation of ZTD values. Brazilian Center for Weather Forecasting and Climate Studies (CPTEC) of the National Institute for Space Research (INPE), jointly with researchers from UNESP ( So Paulo StateUniversity), has generated operationally prediction of ZTD values to South America Continent (available in the electronic address http://satelite.cptec.inpe.br/htmldocs/ztd/zenithal.htm). The available regional version is obtained using ETA model (NWP model with horizontal resolution of 20 km and 42 levels in the vertical). The aim of the present paper is to investigate the ZTD seasonal variability over South Americacontinent using NWP and the humidity convergence zones influence in the ZWD values. This work contributes with ZTD modeling over South America continent using NWP identifying where and when the ZTD values present lower predictability in this region, and consequently, minimizing the error in the GNSS (Global Navigation Satellite System) positioning that apply this technique. |
