Trend in Ground-Based GPS Sensing of Atmospheric Water Vapour: The Malaysian Perspective

Abstract: Atmospheric water vapour is the most variable component of the atmosphere. It plays a crucial role in Earth‘s energy balance and hydrological cycles. Because of its temporal and spatial variability, accurate measurement of atmospheric water vapour has been very challenging in meteorology. However, the Global Positioning System (GPS) offers detailed coverage, all weather and continuous observations. Therefore, exploring this potential to deliver atmospheric information is now termed ‗GPS meteorology‘. This pape… Show more

“…In recent years, many studies have been carried out to probe and detect changes in IWV by deploying a variety of datasets retrievable from different sensors or platforms, including radiosonde [8,9], microwave radiometers [10], Global Positioning Systems (GPS) [11][12][13], Raman Lidar [14], and satellite remote sensing [15]. Traditionally, observation records from radiosondes represent an important resource for monitoring the variability and trends in IWV because of its accuracy and vertical resolution.…”

“…While observations from sun photometers are limited to cloud-free regions, low spatial resolution restricts the use of space-based instruments. Since the introduction of GPS as an efficient meteorological tool by [11], its data are frequently used to determine precipitable water, among other atmospheric parameters. The temporal span of GPS data, however, falls short of the minimum period (30 years) required to aggregate weather for the evaluation of climatic effects in an area, as described by the World Meteorological Organization (WMO) [21].…”
