Resource: stat_prior

This resource is used to specifically set the station priority. Otherwise the station priority is set based on the size of the domain.

Each station in the city database is prioritized. The highest priority (1) represents the largest cities such as Chicago O'Hare and Los Angeles International. An effort has been made to keep these stations evenly spaced to provide the best plots.  Priority 2, 3 and 4 stations fill in the gaps between the stations of higher priority.  Priority 5 stations are near other reporting stations and priority 6 are within large cities such as Chicago's Midway airport.

Automated priorities

For plotting, only the highest priority stations get plotted depending on the size of the domain. As the domain size decreases, the program will automatically include more stations, lowering the priority. The domain size is computed from the plot domain as:

   domain_size =(ny-1)*dy

The priority associated with the computed domain size is listed in the table above.

Relative priorities

You can specify a relative priority that is based on the automatic priority computed from the domain size.  By using "+" or "-" on the priority, it will modify the automated priority either higher or lower, respectively.  For example, the domain size is computed at 15.  The automatic priority is 3.  If the station priority is "+1", the new automatic priority will be 4.  Now if the plot size changes, the priority will always be one more than the computed automatic priority.
