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 dont always agree
• But we do care about one another!
• Think out of the box
• Development of scientific collaborations

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.

Some overarching questionsResearch

• 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
Some overarching questionsApplications

• 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.)

7
Some overarching questionsValidation

• 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?

8
Some overarching questionsNew
Technologies/techniques

• 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?

9
Other topics

• Formation of IPWG sub-committees?
• Snowfall
• Nowcasting
• Web site
• PEHRPP
• Liaisons with other groups
• GEWEX
