Dust radiative forcing + satellite
WebMay 15, 2013 · In the dust layer, longwave radiation emitting by dust cools the atmosphere, which counteracts about 17% of shortwave heating of atmosphere during daytime and results in cooling of atmosphere simply during nighttime. At the same time, the atmosphere beyond the dust layer is warmed because of absorbing the LW radiation emitted by dust … WebOct 5, 2024 · Radiative forcing induced by snow darkening from BC (LAPRF BC) and dust (LAPRF dust) deposition also decreases and increases with elevation, respectively (Fig. 4d,e ). As a result, the...
