Establishing GPS Network for Monitoring the Perceptible Water Vapor over Nasser-Lake in Egypt

The dramatic change from the abundant rainfall in the 1950s and 60s to much drier conditions from the 70s to the 90s over most of the African countries was the strongest trend in rainfall on the planet of the 20th century. Marked inter-annual variations in recent decades have resulted in extremely dry years with devastating environmental and socio-economic impacts. With a large rural population depending on rain fed agriculture, the abrupt decrease of water resources has been devastating to both populations and economies.

The aim of our proposal is to provide the decision makers with improved assessments of similar rainfall changes which are likely to occur during the 21st century due to natural fluctuations and as a result of anticipated global climate change. An essential step in that direction is to improve our ability to forecast the weather and climate in the north-African region specially Egypt. The primary objective of the proposal is to establish a network of four Global Positioning System (GPS) stations for monitoring the Perceptible Water Vapor (PWV) over Nasser-Lake in Egypt.
