Does H truly cool the solar chromosphere?

Solar Physics Aims and scope Submit manuscript

Abstract

I examine the controversial problem of H radiative cooling in the solar chromosphere. I find, in agreement with Praderie and Thomas, that H is a substantial source of radiative heating in the outer atmosphere, especially when departures from LTE are important. The role of H as a chromospheric heating agent must be considered carefully before net radiative cooling rates can be assessed from empirical chromospheric models, or calculations of nonradiative heating, for example by acoustic waves, can be pursued meaningfully.
