Relationship between nocturnal flows and the transport of atmospheric pollutants in complex terrain
- NOAA/ERL, Boulder, CO (United States). Environmental Technology Lab.
The relationship between the three-dimensional (3-D) structure of nocturnal flows in complex terrain and the transport of atmospheric contaminants has been investigated in two cases, one on the High Plains just east of the Front Range of the Colorado Rocky Mountains and the other in the lower Fraser River Valley (LFV) near Vancouver, British Columbia, Canada. Both studies were in regions where a mountain valley opened into a flatter area, and in both cases the 3-D structure of the flow was mapped out by the scanning Doppler lidar system developed and operated by the Environmental Technology Laboratory (ETL) of NOAA`s Environmental Research Laboratories. In the Colorado case, the author investigated the effects of the flow on SF{sub 6} tracer released from the Rocky Flats Plant (RFP) northwest of Denver, as part of a wintertime model validation study. In the LFV he studied the relationship between nighttime flows exiting a tributary valley and photochemical air pollution products from the previous day.
