Earlier I pointed out that it could / should be better to specifically block solar IR, or in particular those wavelengths absorbed by H2O vapor, other gases and clouds, in the troposphere, rather than block all solar wavelengths indiscriminately (because selective shading could reduce the effect on convection and precipitation — caveats about cloud and H2O distribution... etc.).

In general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that level.
