The dataset contains the analysis and sea ice forecast results from the Alfred Wegener Institute Coupled Prediction System (AWI-CPS). Note that due to the large ensemble used (30) in the AWI-CPS, the output data is generated with only monthly mean data. One who has further interest in the daily output could reach the authors through emails. AWI-CPS.DA.tar.gz has both ocean and sea ice variables, where the variable has a suffix of 'f' means forecast, 'a' stands for analysis, and 'ini' stands for initialized states. AWI-CPS.FCST.tar.gz contains the sea ice forecasts for different lead times initialized in January, April, July and October. The axis 'fcst' for each variable actually represents forecasts with 4 different lead times of L0-2, L3-5, L6-8, L9-11. For example, L0-2 indicates forecasts with lead times of 0, 1, and 2 months, and so forth for other lead times. Both sea ice probability and sea ice concentration before and after the calibration are given in the data file. Specifically, SIP_FCST_CORR is for sea ice probability after calibration, while SIP_FCST_RAW is the raw forecast; SIC_Cal is after calibration, while SIC_RAW is the raw forecast.
