Development of the ClearSky smoke dispersion forecast system for agricultural field burning in the Pacific Northwest

The use of an atmospheric dispersion model to determine influence regions in the Prince George, B.C. airshed from the burning of open wood waste piles

“…CALMET under-estimates the observed winds 71% of the time. These results compare favourably with surface wind evaluations performed with Poor 145 114 39 39 237 83 37 24 718 Fair 25 23 5 5 56 37 14 9 174 Good 36 11 2 6 50 50 38 10 203 All classes 206 148 46 50 343 170 89 the ClearSky smoke forecast system (Jain et al, 2007) and with similar evaluations using diagnostic meteorological models (Cox et al, 2005).…”

“…5, the observed (A) and cross-validation (B) wind roses show CALMET reproduces the dominant North-South wind directions at this location but tends to produce winds more often from the NE than is observed. The average mean absolute error for wind direction was 33 which compares favourably with the observations that show the ClearSky smoke dispersion forecast system performs quite well on days where the forecast wind direction error is less than 30 (Jain et al, 2007).…”

“…As a result, each burn was treated as an isolated buoyant point source with a nominal plume temperature of 398 K and up-draft velocity of 1.0 ms À1 . These parameter values, while consistent with temperature and up-draft velocities reported from agricultural burning (Jain et al, 2007) are estimated values, and as such, contribute additional uncertainties to the calculated surface concentrations.…”

“…A smoke dispersion forecast system (ClearSky) has been developed for management of agricultural field burning in the Pacific Northwest (Jain et al, 2007). Daily MM5 meso-scale model output at 4 km is used as input to the CALMET diagnostic wind field generator (Scire et al, 2000).…”

The Forecasting Plant Trend That Is Appropriate in the Storage of Carbon Dioxide to Fight Global Warming in the Area of Nonthaburi

“…[5,6] The methodologies implemented and recommended by United Nations Framework Convention on Climate Change (UNFCCC) include mitigation of greenhouse gases, reducing emissions from deforestation and forest degradation in developing countries (REDD), land use, land-use change and forestry (LULUCF), emissions resulting from fuel used for international transportation: aviation and marine etc. [7,8] As mentioned earlier that one of the methodologies to reduce GHG is to increase forest as a sink process to absorb carbon in the atmosphere. Many nations design green policies and persuade private sectors to support sustainable development.…”
