TY - JOUR A1 - Hellmuth, Olaf A1 - Feistel, Rainer A1 - Foken, Thomas T1 - Intercomparison of different state-of-the-art formulations of the mass density of humid air Y1 - 2021-12-17 VL - 2 IS - 1-4 JF - Bulletin of Atmospheric Science and Technology DO - 10.1007/s42865-021-00036-7 PB - Springer International Publishing N2 - The differences between one classical and three state-of-the-art formulations of the mass density of humid air were quantified. Here, we present both the calculi for direct determination of the humid-air mass density employing the virial form of the thermodynamic equation of state, and a sufficiently accurate look-up-table for the quick-look determination of the humid-air mass density, which is based on the advanced Thermodynamic Equation of Seawater 2010.
