CAPS 2008 Spring Experiment Ensemble Forecast Product
This demonstration webpage
shows hourly ensemble products (postage-stamp
chart, mean/spread, spaghetti
plots, and probability maps)
of the forecast composite reflectivity and 1-h accumulated
precipitation
fields, along with the available observations
(composite reflectivity mosaic
and NSSL/NMQ 1-h precipitation)
valid at the same times.
