 As we can see, the variable T has vertical levels. In this case, the only level available is at 850 mb. The variable is daily, as we can see in the `TimeStep` element of the list, and the original units are Kelvin.

+There are several options for spatial selection using the `loadData` function. For instance, if we want the whole domain of the dataset, there is no need for specifying the `lonLim` and `latLim` arguments. In the next example, we will load T850 for the whole Iberian Peninsula for the period 1990-1999.

+The matrix in the `Data` element of the returned list contains a matrix with 54 columns, one for each grid point of the dataset, and 3652 rows, corresponding to the daily time series.
