This method tries to maximize using pure observations to find the temperature change and the forcing (you might need a model to constrain some of the forcings, but there's a lot of uncertainty about how the surface and atmospheric albedo changed during glacial times... a lot of studies only look at dust and not other aerosols, there is a lot of uncertainty about vegetation change, etc).

There were lots of studies of atmospheric transmission (and hence aerosol optical depth) starting with the work of Marvin and later Hand of the National Weather Service.

Surely after decades of satellite measurements, countless field experiments, and numerous finescale modeling studies that have repeatedly highlighted basic deficiencies in the ability of comprehensive climate models to represent processes contributing to atmospheric aerosol forcing, it is time to give up on the fantasy that somehow their output can be accepted at face value.»

However, this study focused on the warming effects of black carbon, and did not compare them to the cooling effects of atmospheric aerosols.

The study, published in Nature Geoscience found that humans have caused at least three - quarters (74 percent) of current warming, while also determining that warming has actually been slowed down by atmospheric aerosols, including some pollutants, which reflect sunlight back into space.

Microphysical theories regarding CR - cloud links via ion - mediated nucleation are well developed, and several studies have attempted to incorporate these effects within atmospheric models to estimate the magnitude of potential affects to aerosols and clouds.

Yet observational and modeling studies have shown that these aerosols have led to large regional changes in surface and atmospheric temperatures, the surface energy budget, and rainfall (Ramanathan et al., 2001a; Chung et al., 2002; Menon et al., 2002b).
