Low cost measurements of nitrogen and sulphur dry deposition velocities at a semi-alpine site: Gradient measurements and a comparison with deposition model estimates, Environ
Low cost deposition measurement methods need to be tested for different land classes in Europe. Abstract The conditional time averaged gradient method was used to measure air-surface exchange of nitrogen and sulphur compounds at a semialpine site in Southern Norway. Dry deposition velocities were th...
