Founded in 2002 in Petaluma, 65 kilometres north of San Francisco, HydroPoint has engineered what appears to be the most sophisticated weather-based irrigation system among a growing list of competitors. The company built its primary climate-modelling centre outside of Salt Lake City, programming a supercomputer to simulate local weather for every square kilometre across North Americaall just to water the grass. The centre communicates via a two-way satellite link with control boxes that operate distinct zones of a client's irrigation system. Wires running underground from the outdoor boxes open and close valves in the water lines. Every night the climate centre broadcasts local weather-related data to a microprocessor inside each controller, which runs software that uses the information to compute precisely how much and when to water its zones, customized to one of 18 plant types as well as other factors like soil type and ground slope.
Question: The weather conditions of every square kilometer in North America necessarily differ.

A. true
