Using National Weather Service rain and temperature reports, Climate Corp tracks weatherautomatically. A grower can also log in and see the data immediately.

“They know exactly what the policy says. Maybe it says ‘if there are more than three 92-degree days in July, that’s a trigger for payment.’

“It’s all based on the idea that there’s a strong correlation between weather and yield. We’ve done studies on this in different parts of the country and can say, with 90 to 95 percent certainty, that when a certain weather events happen you’ll lose 15 bushels or 25 bushels. And we’ll pay you accordingly.”

Is it also correlated with pests and disease that tend to show up in, or after, certain weather?

That’s factored in, says Hamlin, “because we’re taking account the historic yields a (certain) area has seen under certain weather. When it’s wet and there’s standing water in a field, the yield loss is partly from the crop being starved of oxygen, partially from nutrients leached from the soil and partially from disease pressures.”
