We use NLTE modelling of the alkali resonance lines and of C I and 0 I high-excitation multiplets to test their quality as temperature diagnostics of the upper photosphere, in the context of Avrett's NLTE recovery of the LTE Holweger-Müller model below the temperature minimum and Ayres' bifurcation into hot and cool components above the temperature minimum.
