Table 1. Comparison of R2 values for streamflow metrics based on calendar vs US water year.

Category Variable description Source Annual metric Unit No. layers Spatial resolution Temporal coverage
The comparison is based on 2,484 stations north of 40N latitude, monitored for at least 30 years in the period 1960-2015. The R2 was calculated from log-transformed values. LT: long term; YR: yearly.
