13-17 October 20084 th International Precipitation Working Group (IPWG) Workshop – Beijing, China 3 Your task … Key to WG success are: Active participation! Contributions to WG discussions and WG report Your opinions –There is no right or wrong –We are “family” We don’t always agree But we do care about one another! –Think “out of the box” Development of scientific collaborations
4
13-17 October 20084 th International Precipitation Working Group (IPWG) Workshop – Beijing, China 4 Logistics Sign up for a WG and go to designated rooms Monday (afternoon) –“old business” - addressing outstanding issues (90 mins) (New Technology/techniques to define topical areas) –plenary for brief oral reports (7½ mins each!) Wednesday (afternoon) –“new business” discussions (120 mins) Thursday (morning/afternoon) –WG chairs prepare their summaries –WG reports presented and discussed (15 mins each) –Final plenary: future direction and goals of IPWG, new committees, next meeting, etc.
5
13-17 October 20084 th International Precipitation Working Group (IPWG) Workshop – Beijing, China 5 Some overarching questions… Research How can physically based, multi-spectral techniques be developed and advanced? What is the status of cloud radiative modelling? What is the status of PMW modelling in scattering atmospheres? What is the status and new directions for snowfall retrieval? What are new and emerging technologies that should be utilized in retrievals? –Lightning –Cloud radars What is the status of land surface emissivity for precipitation retrievals?
6
13-17 October 20084 th International Precipitation Working Group (IPWG) Workshop – Beijing, China 6 What are the emerging application areas for satellite precipitation products? –Nowcasting? What are the anticipated needs of the user community and can we help? –Regional algorithms/difficult precipitation regimes? What are current/future issues with satellite missions and sensors? –Transition from SSMI → SSMIS → MIS –Operational follow-on to research missions (GPM, CloudSat, etc.) Some overarching questions… Applications
7
13-17 October 20084 th International Precipitation Working Group (IPWG) Workshop – Beijing, China 7 Are there any new validation sites we should encourage that represent different precipitation regimes? –India, S. Africa, Indonesia, BALTEX, etc.? Are there new validation techniques that should be encouraged? –Better engagement with other communities such as hydrology, transportation, etc? What are the validation needs of the algorithm developers? –Physical validation and of what? How do we utilise error fields in validation? –Physical validation and of what? Some overarching questions… Validation

13-17 October 20084 th International Precipitation Working Group (IPWG) Workshop – Beijing, China 8 What new merged techniques should be pursued? –Role of Numerical Prediction Weather data? –Methods such as OI, etc? What is the status of data assimilation in precipitating atmospheres? (and vice versa)? What new sensors should be developed? What is the status and needs for precipitation climate data record generation? What techniques are needed to mitigate against radio- frequency interference? Some overarching questions… New Technologies/techniques
