    21 In the particular case of global domain selections (`lonLim` and `latLim` arguments set to `NULL`) for forecast data, it is recommended that only single-member, single-year selections are performed, due to the large size of this type of requests. Note that this is just an approximate recommendation. Object sizes also depend on the spatial resolution (CFS has approximately 1º horizontal res., while System4 is 0.75º and WFDEI 0.5º). Similarly, while GCM data will normally return data for the whole Earth (including oceans) for most variables, many observational datasets (like WFDEI) provide only data for land areas.

To this aim, it is possible to aggregate monthly using the argument `time = "MM"`, which dramatically reduces the size of the data, allowing for large global domain data requests (type help("loadECOMS") for details).
