A Mobile Meteorological Monitoring System for Use in Open Burning and Open Detonation Activities

摘要

A mobile meteorological monitoring system of in situ and remote sensors has been designed and constructed to characterize the atmospheric boundary layer from the surface up to 2 to 3 km at facilities which conduct open burning (OB) and open detonation (OD) of surplus (demilitarized) military munitions. Surface layer measurements include horizontal wind speed and direction, air temperature, relative humidity, net radiation, barometric pressure, precipitation, and turbulence. Vertical wind profiles are acquired by a Doppler sodar and a radar wind profiler. The sodar and radar work in unison as a radio acoustic sounding system (RASS) to acquire virtual air temperature profiles. A ceilometer has been included for estimation of the mixed layer height. These remote sensors are mounted on a flat bed trailer which allows easy transport from one OB/OD facility to another. All of the computers used for data acquisition are networked together into a primary computer. The meteorological data are used by an OB/OD for predicting transport and dispersion of emissions released into the atmosphere.
