While IBM is getting sued by the city of Los Angeles, accusing it of covertly mining user data in the Weather Channel app in the US, it’s testing the waters for another hyperlocal weather feature that — coincidentally — relies on data that it picks up from sensors on app users’ smartphones, among other devices, combined with AI at IBM’s end to help model the information.

Today at CES, the company announced new service called the Global High-Resolution Atmospheric Forecasting System — GRAF for short — a new weather forecasting system that says it will provide the most accurate weather for anywhere in the world, running every hour, and in increments of every three kilometers everywhere by way of crunching around 10 terabytes of data every day.
