Pressure and temperature forecast errors over the Pacific Northwest
weather.RdThis is a meteorological dataset that consists of differences between forecasted and observed values of temperature and pressure at 157 locations in the North American Pacific Northwest.
Usage
data(weather)Format
A data frame with the following columns:
- pressure:
Difference between forecasted and observed pressure (Pa)
- temperature:
Difference between forecasted and observed temperature (degrees C)
- lon:
Longitude coordinate of the location
- lat:
Latitude coordinate of the location
Source
The data were obtained from Cliff Mass and Jeff Baars from the University of Washington Department of Atmospheric Sciences. This data set was previously published in the "RandomFields" R package.
Details
These forecasts are from 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, with a forecast horizon of 48 hours.
