Cellphone weather (base) station

Ensure that every cellphone base-station is equipped with basic weather condition collection equipment. The station is already equipped with the means to communicate the data to a central station, so the overhead of providing this service is minimal.

Accurate weather forecasting depends partly upon a high density of observations - this idea will not address the problem of collecting data over the oceans, but with the increasing density of cell-phone coverage, should ensure a better means of tracking weather systems, albeit at generally low altitudes.
