In the following sentence, does 'règnent au sol' mean 'ground level' or ... ?
Thank you in advance.

L'eau est le seul liquide qu'on connaisse dans les conditions habituelles de pression et de température qui règnent au sol.
Water is the only liquid known to man, given/in regular ground level conditions for pressure and temperature.

    Yes, it does, but I would rephrase slightly:
    ... in conditions of pressure and temperature normally found / existing at ground level.
