Helsinki Urban Modeling Workshop
- Use of Helsinki Mesoscale Testbed Data in Urban Atmospheric Modeling
Dates: 15-16 June, 2005
Venues:
Wed, 15 June - Vaisala Oyj, Vanha Nurmijärventie 21,
01670 Vantaa, Finland
Thu, 16 June - Hotel Arthur, Vuorikatu
19, 00100 Helsinki, Finland
Organizers: Finnish Meteorological Institute and Vaisala
Workshop theme:
Convene a small working group of scientists interested in observation and simulation of urban boundary layers. In particular, design optimum observational and modeling strategies for the unique (four-season) Helsinki Mesoscale Testbed, and plan the use of the data for effective modeling of physical and chemical processes within the urban boundary layer.
