     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, sigma^2 equal
     to 0.5  mb^2 and range equal to 50 km.

_U_s_a_g_e:

     data(slp)

_F_o_r_m_a_t:

     A matrix with 150 rows and 6 columns. The columns are:

     _date.obs_ a numeric vector giving the date of observations in the
      YYYYMMDDHH format.

     _id.stat_ a character string giving the identifier of the 
     metereological stations.

     _lon.stat_ a numeric vector giving the longitudes of the 
     metereological stations.

     _lat.stat_ a numeric vector giving the latitudes of the 
     metereological stations.

     _forecast_ a numeric vector giving the 48-hr Sea Level Pressure 
     forecasts as provided by the Aviation (AVN) member of the
     University of  Washington MM5 ensemble.

     _obs_ a numeric vector giving the simulated Sea Level Pressures.
