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.

The measurements discussed in this report are derived from channel 2 — a channel that senses radiation in the layer extending from the surface up to about 15 km.

If one looks at the satellite measurements of radiation from the earth you see that at certain wavelengths the radiation is characteristic of the temperature of the earth's surface.

Abstract Measurements of the flux of downward solar radiation through the atmosphere of Venus and at the planetary surface are reported.

Willis says Your insistence that only 2 w / m2 of solar radiation was reaching the surface of Venus despite actual measurements showing 50 times that much from the Russian spacecraft removes you from the possibility of open honest debate.

The evidence here comes from satellite measurements of infrared radiation escaping from the earth into outer space, from measurements of sunlight reflected from clouds and from measurements of the temperature the earth's surface or of the troposphere, the roughly 10 km thick layer of the atmosphere above the earth's surface that is filled with churning air and clouds, heated from below at the earth's surface, and cooled at the top by radiation into space.

When partnered with cloud remote sensing observations the radiation measurements and retrievals allow the characterization of cloud and aerosol radiative effects at the surface, which is essential in order to quantify the amount of radiative energy available at the surface to interact with heating the air, evaporating water, and interacting with clouds and greenhouse gasses in the atmosphere.

To correct for aerosol absorption of the radiation, ship and buoy near - surface temperature measurements are required to calibrate the SST values.
