Main activities:
* Development/support of operational mesoscale physics

* Participation to national/international field projects

* Joint R&D collaboration in mesoscale

* User support for MC2 community model Development/support of operational mesoscale physics GEM Regional Model

* next version: 24 km => 16 km

* improved physics: surface process scheme (ISBA), condensation schemes (Kain-Fritsch, explicit scheme with mixed phases) GEM-HIMAP

* next version: 15 km => 10 km with similar physics HIMAP-CAGES (Canadian GEWEX Enhanced Study; May-June 1999)

* 10-km version focussed on Mackenzie Delta region in support of field phase: validation of surface processes (mostly snowmelt aspects), BL dynamics and clouds,... Participation to field projects

* Testbed for new parameterization schemes o provide detailed observations for validation of surface processes, BL dynamics and clouds,...

* MERMOZ I, II (June 1996 , August 1997; Montreal Experiment on Regional Mixing and Ozone)

* SGP 97 (2000?) (Southern Great Plains 1997 Hydrology Experiment - Oklahoma) surface forcings, BL evolution * FIRE-ACE (Arctic Cloud Experiment; April 1998)

* CAGES (Canadian GEWEX Enhanced Study; May 1999)

* MAP (Mesoscale Alpine Project) Joint R&D collaboration in mesoscale

* Coupled atmospheric and ocean wave system o two-way coupling; project initiated at RPN, to be continued by AEPRI at Halifax

* Hydrological forecasts: coupled atmospheric
and hydrology models o project initiated with BCHydro; continue within MAP and SSPFF (Saguenay flood)

* COMPARE 1,2,3 (4=VORTEX95?)

* McGill Radar/PCP Project?
