The work is an estimate of the global average based on a single - column, time - average model of the atmosphere and surface (with some approximations — e.g. the surface is not truly a perfect blackbody in the LW (long - wave) portion of the spectrum (the wavelengths dominated by terrestrial / atmospheric emission, as opposed to SW radiation, dominated by solar radiation), but it can give you a pretty good idea of things (fig 1 shows a spectrum of radiation to space); there is also some comparison to actual measurements.

By applying what has been learned about solar radiation changes from the recent measurements from space, we can infer that this gradual build - up in solar activity over several hundred years may have been accompanied by a parallel increase in the radiation received from the Sun.

Harrison & Stephenson (2006) developed the use of these datasets further, investigating the relationship between the ratio of diffuse to total solar radiation (referred to as the diffuse fraction) to provide a proxy measurement of cloud.

There are no direct measurements of solar radiation on climatological time scales, but a variety of circumstantial evidence suggests that longer - term variations do occur, perhaps with larger amplitudes than those found in the two most recent eleven - year Schwabe cycles.
