Table 1 Definition of agreement and disagreement frequencies between Sentinel-3 snow cover fraction product (SCF) and snow depth measurements at climate stations. The \(\:a\), \(\:b\), \(\:c\), and \(\:d\) frequencies are used to estimate the overall accuracy (Eq. 1) and SCF over- and under-estimation errors (Eqs. 2 and 3).
