Planned BIG simulations Answer science questions (guided/ verified by observations): • Search for the genesis of Supergranules • Understanding the near surface magnetic network • Search for the genesis of the near surface shear layer • Understanding the dynamics around Sunspots • Search for the genesis of the Solar dynamo • Understanding differential rotation • Understanding the dynamics in the tachocline neighborhood Provide calibration data: • Interpretation of observations • Local Helioseismology • Global Helioseismology Missing: • Data assimilation & forecasting capabilities • Link between global and near surface simulations • Link between solar interior, atmosphere & solar wind
