FEBRUARY 2004 AMERICAN METEOROLOGICAL SOCIETY | S cientific research on atmospheric processes and weather forecasting frequently leads to improvements in weather forecasts [such as quantitative precipitation forecasts (QPF)], as measured by scientific criteria. Furthermore, effective use of such improvements has the potential for avoiding injury and death, averting property and environmental da...

The IPCC Special report on “Global Warming of 1.5 °C” identifies the greenhouse gas emissions trajectories compatible with global mitigation goal Paris Agreement, presents actions required to follow these and analyses synergies trade-offs sustainable development objectives. assessment highlights necessity implement drastic carbon reductions in short term, reach neutrality between 2050 2070 targ...

this study was focused on measuring air pollutants emission from factories producing the asphalt related products in delijan industrial estate, which is the main center of asphalt related products in iran. emissions of four factories were analyzed for air pollutants using a stack analyzer, testo 360, testo co., and germany. the average concentration of all measured stacks for pm, thc, co, nox, ...

this study investigates monthly and seasonal variations of carbon emission from the soil at different grazing intensities. three areas of exclosure, low and high grazing intensities were selected in ghoosheh region of semnan province. carbon emission was measured monthly, in each treatment applying alkali traps (csc) during a year. emission and grazing data were analyzed, using a factorial expe...
