Abstract:

Urban toxic chemical releases pose a threat to the military and civilians. The White Sands Missile Range WSMR Urban Studies address two critical elements in diagnosing airborne hazard releases, namely, airflow chemical distribution and stability chemical concentration. This document provides a qualitative assessment of seven airflow features targeted by the WSMR 2007 Urban Study W07US. The W07US stability assessment is published separately. The features identified for verification and characterization include the Fetch Flow, Velocity Acceleration, Velocity Deficit, Cavity Flows, Canyon Flows, Leeside Corner Eddies, and Reattachment Zone. Feature definitions, frequency of occurrencesday, and field study statistics are presented. Case studies enrich the text with excellent examples of inter-feature attributes and the detailed temporal and spatial urban characteristics. Suggestions for future airflow analysis work are interwoven throughout the text. The conclusions and recommendations recap key findings and next step suggestions for the W07US airflow qualitative assessment.
