Abstract

Careful GPS data processing provides precise estimates of Zenith Path Delay (ZPD), and the absolute ZPD is crucial for meteorological applications. Typically the process of GPS ZPD estimation requires a large network of GPS reference stations to achieve a stable value for the absolute ZPD. The focus area of this study is the Malaysian peninsula. GPS network in South-East Asia has been utilised in this study as the aim is to investigate the zenith path delay of the focus area. GPS data processing and analyses have been conducted during the periods of the North-East and South-West monsoon, when the largest variations in the magnitude of the tropospheric delay could be expected. The variations of the zenith tropospheric delay estimated from a local and a regional GPS network were compared to the results obtained from the global IGS network.
