【 摘 要 】

The line of inquiry which the ASU lidar group has been investigating, with collaboration and support from LLNL, is to create approaches and algorithms for better utilizing the rich information available through modern remote sensors in dispersion modeling systems. In particular, our goal is to create a lidar-data-driven dispersion model mode in ADAPT/LODI. This report describes progress towards this goal during the 2002/2003 academic year. Because of the nature of lidar data and the necessity to utilize additional information, both numerical and measured, this is essentially a data retrieval and data fusion project. With the current generation of commercially available lidar, the scope of the domain in which we are interested is initially 4 to 14 kilometers in radius, where the potentially scanned domain is roughly hemispherical. Figure 1, for example, taken from a recent lidar deployment in Oklahoma City, shows visually the most typical range of the domain that can be probed with the ASU lidar. Ranges 2 or 3 times the distance to the cluster of buildings in the photograph can be probed with a properly functioning, commercially available lidar. This could be of significant value for protecting key buildings with roof-top located remote sensors coupled with dispersion models.
