## Pressure and temperature forecast errors over the Pacific Northwest

### Description

Meteorological dataset, which consists of difference between forecasts and observations (forcasts minus observations) of temperature and pressure at 157 locations in the North American Pacific Northwest.

### Usage

    data(weather)

### Format

The data frame `weather` contains the following columns:

pressure

  in units of Pascal

temperature

  in units of degree Celcius

lon

  longitudinal coordinates of the locations

lat

  latitude coordinates of the locations

Furthermore, some results obtained from the data analysis in `jss14` are delivered that are `pars.model`, `pars`, `whole.model`, `whole`.

Finally, the variable `information` contains packing information (the date and the version of RandomFields)

### Details

The forecasts are from the GFS member of the University of Washington regional numerical weather prediction ensemble (UWME; Grimit and Mass 2002; Eckel and Mass 2005); they were valid on December 18, 2003 at 4 pm local time, at a forecast horizon of 48 hours.

### Source

The data were obtained from Cliff Mass and Jeff Baars in the University of Washington Department of Atmospheric Sciences.
