Eddy correlation measurements of dry deposition fluxes using a tunable diode laser absorption spectrometer gas monitor

An instrument package, based on a tunable diode laser absorption spectrometer comprehensive micrometeorological instrumentation, has been successfully developed for making dry deposition flux measurements, using eddy correlation techniques. Preliminary results from the field testing and evaluation of the instrument package at a rural location are presented. Low deposition velocities were measured for NO sub(2) and SO sub(2) to snow.
