Specialty Session at the Fourth Symposium on the Urban Environment

Sharaton Norfolk Hotel, 20-24 May 2002, Norfolk, Virginia, USA

Jason Ching (a letter to the urban climate e-mail list)

Dear Colleagues, as you know, the Fourth Symposium on the Urban Environment, sponsored by the American Meteorological Society, and organized by the AMS Board on the Urban Environment will be held 20-24 May 2002 in Norfolk, Virginia at the Sheraton Norfolk Hotel. The symposium is being held in conjunction with the 25th Conference on Agricultural and Forest Meteorology and the 12th Joint Conference on the Applications of Air Pollution Meteorology with the Air and Waste Management Association. A number of joint sessions are planned between the conferences. Further details: http://www.indiana.edu/~climate/grimmond/conference

Sue Grimmond and I thought it useful to arrange for a specialty session at the Fourth Symposium on the Urban Environment. The subject of that session is "Developing and improving urban morphology descriptions and building databases for modeling the urban environment in mesoscale models" .

Briefly: Models for predicting the transport and air quality for urban environments require information as well as parameterizations for the land use, surface composition, building data and urban morphology. The requisite degree and detail of the urban landscape information will differ for the wide spectrum of model applications and use, ranging from general air quality assessments in mesoscale models to details of flow and dispersion in street canyons with modeling approaches such as CFD.

Recognizing the fundamental need for appropriate treatments of urban features to urban modeling, this Specialty Session at the Urban Environment Conference will provide a forum for reviewing and assessing the current modeling methodologies and building database resources in current use, and provide for discussions and recommendations on means to improve upon these methods and databases. We seek to share experience with (a) new data sources, their data preparation, (b) developments of advanced morphology descriptions (e.g., treatment of urban landscapes, landuse categories, building and green area mixes, building heights/densities/distributions) (c) gridding modeling parameters such as roughness, surface reflectivities, planar and frontal building packing densities, buildings-vegetation mix, and others) and (d) sensitivity studies that provide guidance towards balancing specificity and detail to match the different applications and needs.

The session will consist of both invited and contributed presentation. If interested, please indicate that you wish your proposed presentation to be included in this Specialty session. Contact Jason Ching (919 541-4801, ching.Jason@epa.gov) or Sue Grimmond (812 855 7971, grimmon@indiana.edu for further inquiries regarding this Session.

The deadline for submission of abstracts is rapidly approaching, it is November 15th 2001. Again, for further details on the conference http://www.indiana.edu/~climate/grimmond/conference
