How about for my project of positioning remote weather stations in wilderness areas that are used by back country hikers, but are otherwise inaccessible. These locations are far from any standard communications systems. To obtain accurate weather information prior to undertaking such a strenuous and potentially dangerous trek could be life saving.
By the time you arrive in a wilderness area, it's too late to cancel your trip due to unexpected weather conditions.
Other than a system that can use sat comms to relay this vital weather information, there is no way to be aware of the conditions before you are in the midst of them.
