The ozone maximum deposition velocity occurred at around midday, V d = cm s-1, and was zero overnight. The net flux of nitrogen oxides was upward, with a diurnal Author: D.

If the price decreases, we will simply charge the lower price. The AIRMoN-dry program relies on a two-tiered approach that infers dry deposition from air quality, meteorology, and surface observations and directly applies eddy flux and/or gradient techniques. These methods yield average dry deposition rates to areas, typically many hundred meters in radius, surrounding observation points.

Eddy correlation measurements of water vapor flux density have been made by using a barium fluoride film humidity sensor and a three‐dimensional anemometer. During morning and evening periods, good agreement was obtained between eddy correlation data and two independent methods.

Serious disagreement between measurements occurred only when the humidity sensor was operating within a. National Research Council. Acid Deposition: The National Academies Press.

The paper presents results of the investigations on numerical computations and experimental verification concerning the influence of selected parameters of the cutting process on the stress state in bundles of cold-rolled steel sheets being cut using a guillotine.

Eddy covariance is a micrometeorological technique that measures the total exchange CO 2 and H 2 O at the ecosystem scale. There were early eddy covariance systems for measuring fluxes of water vapour, but in the s reliable fast‐responding CO 2 analysers became widely available and in several centres the technique was developed to measure Cited by:
