Overview ADCP Data

Overview ADCP Data#

Comparisons between each model and ADCP datasets are shown below, first in Taylor diagrams, then in maps of skill scores where each marker is colored to indicate the skill score of the comparison.

The two models perform similarly to each other with the exception of increased variance in CIOFS Fresh for subtidal variable comparisons. They both generally perform well for tidal time series and only moderately well for subtidal time series.

Taylor Diagrams#

Taylor diagrams summarize the skill of the two models in capturing the ADCP moorings. The data has been grouped by region (Figs. 122, 123, 124) and season (Figs. 125, 126, 127). The results show that CIOFS fresh and CIOFS hindcast perform similarly for tidal results. For the subtidal along-channel velocity component by region, CIOFS Hindcast and CIOFS Fresh have mostly similar correlation coefficients, but CIOFS Fresh has more accurate variance. By season, CIOFS Fresh has more accurate variance again though in the spring both models have too high of variance. For the across-channel subtidal component, the two models again have similar correlation coefficients but CIOFS Fresh has more accurate variance in Upper Cook Inlet; in Kachemak Bay and Central Cook Inlet CIOFS Hindcast is more accurate. When considering subtidal speed, we see that the two models perform similarly to each other. Skill scores are shown in the next plots for each dataset.
