Narrative:

We were cleared to land on runway 9L. Weather was IMC cat III and we were doing auto-land. At less than 500 feet; approximately 300-350 feet AGL tower told us to go-around. We complied. They did not tell us to fly the published missed approach or fly straight ahead - we had to query them on this; and then they told us to fly the published missed approach. They had other traffic go-around as well. Later they explained that runway 9L runway incursion predictive system was giving them false warnings; and they temporarily closed the runway to fix it. They redirected us to land runway 9R and we made an uneventful autoland on runway 9R.
