Stream Temperature Model Evaluation
The following 3 graphs show examples of the observed and predicted temperatures at sites
with low, medium and high dampening factors (D).
All 96 graphs are also available.
The 96 station-years together have 7163 observed stream temperatures within the
period of July 1 through September 15.
The mean absolute error for the model here is 1.26°F.
The largest error is 9.01°F, but 95% of all errors are below 3.51°F.
Of the total errors, 52.3% are under 1.0°F and 75.2 % are under 1.0°C.
The correlation between the observed and predicted stream temperatures is 0.933
and is seen in the following graph.
The following graph shows that within the target period, there is little sign of seasonal bias.
The errors, however, do tend to be larger during the early and late seasons.
