Urban-Small Building Complex Environment: W07US Stability Analysis and Inter-Study Comparison, Volume AS-2; Final rept

摘要

Urban atmospheric stability patterns impact military and civilian health, tools, operations, and planning. By identifying repeatable urban stability patterns, improvements to each of these impacted areas can be achieved. In this report, the White Sands Missile Range (WSMR) Urban Study research project is reviewed with a focus on stability characterization; specifically, the stable urban environment. Results from the WSMR 2007 Urban Study stability assessment are described and contrasted with the previous two urban studies. Eight stable environment characteristics were gleaned from the inter-Study analyses. The stable conditions observed showed an extremely consistent temporal pattern. The spatial distribution proved inconsistent however, the seasonally similar field studies showed patterns worthy of special note. Examples of the seasonally-similar stable patterns are given. A short summary of stable environment characteristics observed thus far are tallied in the Summary and several recommendations for subsequent research conclude the technical report. Preliminary results from the ongoing higher time resolution analysis are documented in appendix A.
