Prototype Interactive Intercomparison of Rainfall Products

The International Precipitation Working Group (IPWG) focuses on operational and research satellite based quantitative precipitation measurement issues and challenges. In support of IPWG goals, this interface is designed for visualization and analysis of the Prototype Interactive Intercomparison of Rainfall Products.
Users can generate plots or ASCII Output for area average (Lat-Lon Map), time series (Time Series), and Hovmoller diagram. The animation is available for Lat-Lon Maps. Selecting here or the Help buttons will open a new window with detailed help. More details about the data are also available.
