Description: Maps of tidal energy dissipation rates, that were calculated for three different rotation periods (12h, 18h and 24h) using the Oregon State Tidal Inversion Software, are implemented as oceanic bottom heat flux into CLIMBER-3α to investigate the impact of tides on early Earth’s climate. For each length of day corresponding paleoclimatic scenarios each of which with three different atmospheric carbon dioxide abundances, are simulated. We use the relatively fast intermediate-complexity model CLIMBER-3α to be able to run a large number of simulations. CLIMBER-3α consists of (1) an improved version of the ocean general circulation model MOM3 run at a coarse horizontal resolution of 3.75 x 3.75 degrees with 24 vertical layers, (2) the sea-ice model ISIS operated at the same horizontal resolution and capturing both the thermodynamics and dynamics of sea ice, and (3) the fast statistical--dynamical atmosphere model POTSDAM-2 with grid cells measuring 22.5 degrees in longitude and 7.5 degrees in latitude. The main limitations of the model relate to its simplified atmosphere component. Tide model simulations of the Oregon State Tidal Inversion Software were used to compute tidal energy dissipation data. For more details see the corresponding article (Biewald et al., XXXX)
