Abstract:
In the years following the arrival of ESA’s Rosetta probe at comet 67P Churyumov-Gerasimenko in Summer 2014, the expected plethora of orbiter and lander data will certainly lead to very detailed modelling of thermally driven comet activity and other phenomena.

We review the most frequently used thermophysical data for cometary volatiles (water, CO, CO2) and dust and recommend precise correlations for the widest temperature ranges, including uncertainty estimates. The temperature dependence of surface material thermal inertia is estimated.

The results of comparisons between different modelling teams performed in preparation of Rosetta's mission is discussed.
