prcpGrid | R Documentation |
This data set gives 48-hour forecasts of 24 hour accumulated precipitation on a grid of locations in the US Pacific Northwest initialized on January 13, 2003 OOZ and valid on January 15, 2003 OOZ. The ensemble forecasts come from a nine member version of the University of Washington Mesoscale Ensemble (Grimit and Mass 2002; Eckel and Mass 2005). Precipitation amounts are quantized to hundredths of an inch.
A data frame with 8188 rows and 11 columns:
avn/gfs,cent,cmcg,eta,gasp,jma,ngps,tcwb,ukmo
forecasts from the 9 members of the ensemble (numeric).
latitude
the latitude of each forecast (numeric).
longitude
the longitude of each forecast (numeric).
