^aRMSD, bias, uRMSD, and Pearson’s correlation coefficient (r) are computed between each model estimate and in situ measurement (see Appendix A for details). The number of stations (N) varies mainly due to different model simulation periods and in situ data availability. Note that Models 15, 16, and 21 did not provide model estimates of NO₃, which is indicated by a dash (−).
