Interim user's guide to the RADM scavenging Module Version 1. 0. Interim report

Technical Report ·
OSTI ID:7058697

The report is an interim version of the user's manual for the RADM Scavenging Module (RSM). The scavenging module simulates wet removal and aqueous-phase chemical processes as they occur on a regional scale. It is designed for inclusion into a regional-scale Eulerian code that does not explicitly account for processes involving clouds and precipitation. Using surface precipitation rates and vertical profiles of temperature and moisture for a regional-scale grid square, the scavenging module calculates steady-state cloud, precipitation, and vertical velocity fields for subgrid areas representing stratiform, convective, and fair-weather cumulus clouds. It then calculates the effects of aqueous-phase chemistry, precipitation scavenging, and transport on the pollutant fields presented by the host code for a specified time period (one hour). The version of the RSM described in this report includes the stratiform and convective storm component; it does not include the fair-weather cumulus (although provisions for including this component are outlined). A description of several proposed benchmark tests is provided; the results of these tests will be published in future reports.
