Not all weather forecasts were created equal—until now.

Weather is a powerful force
No one is immune to the weather. Increasingly volatile, weather drives the decisions we make each day and can take thousands of lives and cost billions in economic value each year. Having access to accurate and reliable weather information is increasingly important as the number of severe weather events continues to climb.

Global forecasts have lacked accuracy
This is due to a lack of specialized weather equipment and models that update infrequently (~every 6-12 hours) and at a resolution too wide to capture many weather phenomena (~10km ).

Improved global mapping of the atmosphere
In order to get a closely-knit look at the weather, one must understand what is happening everywhere in the atmosphere. We partnered with the National Center for Atmospheric Research (NCAR) to improve its latest-generation global weather model, which uses state-of-the-art science to forecast the atmosphere at a truly global scale.

Better data and observations
The sheer disparity in modelling most areas of the globe stems from a lack of specialized weather equipment and reliable datapoints available. IBM GRAF has the capability to incorporate previously untapped data sources from airplane sensors and pressure sensor readings from smartphone users (with consent) to help overcome the lack of specialized weather equipment in many parts of the world.
