Filling the Gap: Why Oceans and the Global South Matter


Forecast models begin with a best guess of the atmosphere called the initial condition. That guess is only as good as the measurements behind it. Today, coverage is densest over North America and Europe and thinnest over oceans and the Global South. The result is familiar: storms that intensify faster than expected and regional forecasts that degrade just when decisions are most time-critical.

Target the blind spots

Thinking Balloon focuses on the blind spots. By streaming fresh vertical profiles and winds across the Indian Ocean basin and remote latitudes, we reduce initial-condition error and slow error growth. Better inputs make every downstream model (AI or physics) behave better.

From uncertainty to action

This isn’t about replacing satellites or radiosondes. It’s about finishing the picture: placing observations where they move the needle most. That’s how we turn uncertainty into operational guidance for grid operators, airports, and agencies across India and beyond.
