Dear GCSS participants We will be holding a joint Microphysics/Polar Cloud Working Group meeting at the University of Washington in Seattle on the 24-25th June 2010. Since Microphysics is a cross-cutting activity, there will also be participation from many of the other working groups. Further details will follow, but it is likely that topics of discussion will include: - the 1D kinematic microphysics intercomparison - polar cloud modelling and observations - polar cloud/climate interactions - the SHEBA intercomparison - the TWP-ICE intercomparison - the RICO intercomparison as well as discussion of future cases we might like to consider. Further details will be forthcoming, but If you would like to participate then please email ben.shipway@metoffice.gov.uk. If you would like to give a talk on one of the above topics or suggest an additional area for discussion, then please include a short abstract by 15th March (but note that since this is only a 2 day workshop we won't be able to accommodate a large number of talks). The dates of the meeting have been chosen to immediately precede the AMS cloud and radiation conferences in nearby Portland (http://www.ametsoc.org/Meet/fainst/201013atmosrad13cloudphysics.html). Look forward to seeing you there.
