slp: Sea-Level Pressure Ensemble Forecasts and Observations
Description
This data set gives 48-hour sea-level pressure forecasts for the
US Pacific Northwest from a 5 member ensemble at the University of Washington
(UW MM5) and the associated observations for five different stations
for the period from April 16, 2000 to June 30, 2000
at 0 hours GMT, using a 12-km grid resolution.
Note that forecasts are not available for some of the interim dates.format
A data frame with 205 rows and 11 columns:
AVN - forecasts from the AVN member of the ensemble (numeric).
GEN - forecasts from the GEM member of the ensemble (numeric).
ETA - forecasts from the ETA member of the ensemble (numeric).
NGM - forecasts from the NGM member of the ensemble (numeric).
NOGAPS - forecasts from the NOGAPS member of the ensemble (numeric).
observation - the observed sea-level pressure (numeric).
date - the date of each forecast/observation set,
in the format YYYYMMDDHH (categorical).
latitude - the latitude of each forecast/observation (numeric).
longitude - the longitude of each forecast/observation (numeric).
station - weather station identifier (categorical).
type - weather station type (categorical).Details
This dataset is a small subset of the data used in Raftery et al. (2005),
provided for the purposes of testing. Typically forecasting would be
performed on much larger datasets.References
