We have developed online prototypes in the GIOVANNI TRMM Online Visualization and Analysis System (TOVAS) to address these issues. There are four online tools to allow inter-comparing 3-hourly, daily, monthly and climatology of the existing and previous versions of TRMM Multi-satellite Precipitation Analysis (TMPA) products (3B42, 3B43) and their near-real-time products (3B42RT). For TRMM monthly products, users can inter-compare them with their current and previous versions as well. Users can use these tools to analyze the products, generate plots and download customized data for further analysis, e.g. comparing their gauge data. Examples from these tools will be presented.
The future plans include 1) integration of the IPWG (International Precipitation Working Group) Validation Algorithms/statistics in TOVAS; 2) add more Level-3 monthly TRMM products; and 3) add more climatology datasets derived from Level-3 TRMM monthly products.
