Table 1 The overall performance of the KF bias correction for 24-h, 48-h, 72-h forecasts and MOS bias correction for 72-h forecasts based on the five metrics (bias, MAE, RMSE, CRMSE, and correlation coefficient)
From: System bias correction of short-term hub-height wind forecasts using the Kalman filter

KF bias correction (24 h) | − 0.16 | 2.28 | 2.92 | 2.91 | 0.67 |
KF bias correction (48 h) | − 0.18 | 2.32 | 2.99 | 2.98 | 0.66 |
KF bias correction (72 h) | − 0.19 | 2.34 | 3.01 | 3.00 | 0.66 |
MOS bias correction (72 h) | 0.19 | 2.49 | 3.22 | 3.21 | 0.59 |
