WebbMy overall research objective is to understand aerosol sources and parameterize these for use in climate and air quality models. The work includes both man-made sources, natural sources, and anthropogenic permutations of natural sources. So far this includes sea spray aerosols, road traffic aerosols, tropical forest aerosols as well as the influence of … WebbEffekt anger inom fysiken den mängd energi som omvandlas per tidsenhet. Effekt betecknas ofta med bokstaven P från engelskans power och kan bland annat yttra sig i form av ett värmeflöde eller mekaniskt arbete. SI-enheten för effekt är watt (W), där en watt motsvarar en energiomvandling på en joule per sekund (W=J/s).
Webbrepresents an important uncertainty contribution, is the size-of-source effect (SSE). The SSE is a phenomenon associated with the change in the radiation thermometer output signal due to changes in the size of the source [5,6]. The SSE phenomenon is rather well known and described for classical (industrial) radiation thermometers [7,8], for which
