The Global Circulation of TPW at High Temporal Resolution from Microwave Satellites

Analyses of Total Precipitable Water are widely used by the scientific community over a range of applications (e.g. atmospheric rivers, tropical cyclone development, Saharan Air Layer depiction, monsoon/MJO evolution). The Tropical Cyclones Group at CIMSS developed an advanced real-time animated visualization of TPW over the oceans from integrated multi-satellite data, called 'MIMIC-TPW,' operating in real-time since 2010. This poster presents a major development in the algorithm to transition to the widely-used MIRS (Microwave Integrated Retrieval System) retrieval of TPW, which enables *global* observation of TPW evolution (including over land and sea ice), and improved TPW retrieval in areas of precipitation. Using this new method we will demonstrate the improved understanding of TPW possible at the land/sea boundary, the tropical/extratropical interface, and in the MJO.
