Description Usage Format References

This data set gives 48-hour forecast and simulated observed
Sea Level Pressure (measured in millibars, mb) for 59 stations located in
the Pacific Northwest.
The 48-hour forecasts of Sea Level Pressure were provided by the Aviation (AVN)
member of the University of Washington MM5 Mesoscale Ensemble. The observed
Sea Level Pressure values were simulated for each day using a Multivariate
Normal distribution with exponential covariance structure. The parameters used
for the exponential covariance structure were: nugget effect, equal to
*0.1* *mb^2*, *σ^2* equal to *0.5*
*mb^2* and range equal to *50* km.
