AN INTERDISCIPLINARY APPROACH FOR THE DEVELOPMENT OF GNSS METEOROLOGY IN ROMANIA
Abstract
Water vapor monitoring represents a vital pr ocess in understanding the global climate and predicting the weather, especially rainfall events. Knowledge of the total amount of water vapor and its distribution, both spatial and in time, is considered also to be the key to a more accurate description of the state of the atmosphere that can lead to improved numerical weather prediction models. GNSS Meteorology refers to the mapping of integrated water vapor throughout GPS networks and their corresponding tomography, as well as GPS radio occultation. The objectives of this particular branch of interdisciplinary geodesy are achievable under the premises that GNSS technology has a series of advantages that recommends its use for operational meteorology and climate research rather than more expensive meteorological solutions. This study is concerned with the identificati on of the basic concepts that stand before GNSS Meteorology and the strategies applicable to be able to satisfy the meteorological requests of GNSS-derived products, as well as the detection of a proper way of validation for GNSS water vapor data and some improvement techniques. This application of the Global Positioning Systems has also an important benefit for the geodetic community, namely the potential of tropospheric model development after a better understanding of our surrounding atmosphere.
