Significant wave height (SWH)
conditions observed from
satellite observations
Average satellite SWH
Histogram of all observations and 7 days averages of
satellite SWH
Validation: Scatter plot and mean
errors
All pairs of WAM (0-6 hour) and satellite observations have been used.
The number of observations in each 5x5 cm box is shown with
colors. The red line represents the best fit to the data whereas the
white
dashed line represents a one to one relationship.
Errors in 2 dimensions
Average error statistics have been calculated over 100 km bins,
to provide enough observations to obtain reliable 2D error estimates
Bias (WAM - altimetry)
Stddev
Scatter index
Error statistics vs. forecast length
Bias, RMS and correlations have been calculated over the whole domain,
for every hour of WAM forecast, up to 54 hours
Bias and rms errors
Correlation and explained variance
Error statistics vs. waveheight
The bin size is 1 meter
Bias, stddev and rms errors
Temporal error statistics:
Bias stddev and RMS have been calculated for weekly averages
RMS (red), std (blue) and bias (green)
