For a given system or experiment, specifies how the analyses and forecasts were produced. In Seasonal Forecast system 2, method=0 denotes the case when no ocean data assimilation was used to prepare ocean initial conditions; method=1 is the standard case of data assimilation. From Seasonal Forecast System 3, for the standard forecasts (up to month 7), request method=1. For the longer range forecasts (out to month 13), request method=3 (the first 7 months of METHOD=3 data for each extended integration is a simple copy of the corresponding METHOD=1 data).
Example to specify 2 metre temperature from the multi-model seasonal forecast system 5:
