srft: Surface Temperature Ensemble Forecasts and Observations

Description

This data set gives 48-hour forecasts of 2-m surface temperature and the associated observations for the US Pacific Northwest from January 1, 2004 to February 28, 2004. The ensemble forecasts come from an eight-member version of the University of Washington Mesoscale Ensemble that was operational in 2004. Note that forecasts are not available for some of the interim dates.

Arguments

format

A data frame with 36826 rows and 15 columns: CMCG - forecasts from the CMCG member of the ensemble (numeric). ETA - forecasts from the ETA member of the ensemble (numeric). GASP - forecasts from the GASP member of the ensemble (numeric). GFS - forecasts from the GFS member of the ensemble (numeric). CENT - forecasts from the CENT member of the ensemble (numeric). JMA - forecasts from the JMA member of the ensemble (numeric). NGAPS - forecasts from the NGAPS member of the ensemble (numeric). TCWB - forecasts from the TCWB member of the ensemble (numeric). UKMO - forecasts from the UKMO member of the ensemble (numeric). observation - the observed surface temperature (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 subset of the data used in Berrocal et al. (2006), provided for the purposes of testing. Typically forecasting would be performed on much larger datasets.
