they are not calculated identically, R2 = r2, with r the pearson correlation coefficient https://en.wikipedia.org/wiki/Pearson_correlation_coefficient#For_a_sample NSE = Sum((Pred-Targ)2) / Sum((Targ-Mean(Targ))**2) https://en.wikipedia.org/wiki/Nash%E2%80%93Sutcliffe_model_efficiency_coefficient
See https://github.com/earthnet2021/earthnet-models-pytorch/blob/main/scripts/score_en21x_v2.py#L45
Thank you for your explanation. I misunderstood the calculation formula for R2 as 1 - SSE/SST, which is the same as the formula for NSE.
The calculation formulas for NSE and R2 are essentially the same, but their purposes are different. Why are the values of these two indicators calculated in the paper different?
