CP and PWP calculated using various products compared with values from ISMN sites. (a) PWP derived from NNsm. (b) PWP derived from GSDE. (c) PWP derived from TG. (d) CP derived from NNsm. (e) CP derived from Fu. The r in the upper left corner of each panel represents the correlation coefficient (p < 0.01). MSE is the mean square error.
