Dust radiative forcing + satellite
WebJan 1, 2014 · Direct radiative forcing is defined as the change in the radiative flux by dust particles prior to any response by the climate (e.g., Hansen et al. 2005).Forcing is typically calculated at the top of the atmosphere (TOA), but because the aerosol perturbation to the flux at the surface can be markedly different and modify the hydrologic cycle, the forcing … Webamong the first studies to examine the daytime diurnal variation of dust aerosols using satellite sensor data. 2.
