Tracking Clouds and Rain with low cost GPS chips


GPS or Global Positioning System is a popular technology used for positioning and navigation. However GPS signals can also be used for scientific applications. One application is to track clouds and rain. This is possible because GPS signals are delayed by the effect of water vapor in the atmosphere. In our lab we are exploring the use of low cost GPS chips for tracking clouds and rain. The research project will involve collaboration with Fukushima Renewable Energy Center of AIST ( We have installed several GPS receivers at FREA including high end and low end versions. The research will involve intercomparison of data from the receivers. It also will develop machine learning algorithms to map water vapour to clouds.
