\title{Sample Of Experimental And Observational Climate Data In Function Of Longitudes And Latitudes with Start}
\description{
This sample data set contains gridded seasonal forecast and corresponding 
observational data from the Copernicus Climate Change ECMWF-System 5 forecast
system, and from the Copernicus Climate Change ERA-5 reconstruction. 
Specifically, for the 'tas' (2-meter temperature) variable, for the 15 first 
forecast ensemble members, monthly averaged, for the 3 first forecast time 
steps (lead months 1 to 4) of the November start dates of 2000 to 2005, for 
the Mediterranean region (27N-48N, 12W-40E). The data was generated on (or 
interpolated onto, for the reconstruction) a rectangular regular grid of size
360 by 181.
}
\details{
The `CST_Start` call used to generate the data set in the infrastructure of 
the Earth Sciences Department of the Barcelona Supercomputing Center is shown
next. Note that `CST_Start` internally calls `startR::Start` and then uses 
`as.s2dv_cube` that converts the `startR_array` into `s2dv_cube`.
