Attribution experiment for winter 2015/16 with Indian Ocean SST anomaly of 2019/20 : I20_BC16

Title Attribution experiment for winter 2015/16 with Indian Ocean SST anomaly of 2019/20 : I20_BC16
Description 4-month long 101-ensemble member seasonal attribution experiment (I20_BC16) initialised on 01-November-2015 using the atmosphere-only version of SEAS5 (see Johnson et al., 2019) forced with daily ERA5 SST as in the reference experiment (R16) but with daily SST over the tropical Indian Ocean swapped with that from 2019/20.
