| Description/Abstract | Dry deposition of air pollutants is expensive and difficult to measure. Hicks et al. (1985) proposed the dry deposition inferential model as an alternative approach to direct measurements of dry deposition for large network operations. The inferential model determines dry deposition fluxes as the product of a measured concentration and a modeled deposition velocity. EPA has recently initiated a program to directly measure dry deposition fluxes to evaluate and improve the inferential dry deposition model. A transportable system for directly measuring fluxes of O3, SO2, and HNO3 was built and deployed at two National Dry Deposition Network (NDDN) sites in 1994. The system, instrumentation, and sampling protocol are described briefly herein, along with some preliminary data from the 1994 field program. |
