The data produced by TRMM have “given unprecedented insights into rainfall producing cloud systems over tropical land masses and oceans,” according to NASA. In addition, TRMM has proven to be an invaluable resource to weather forecasting agencies around the world in improving hurricane and typhoon tracking. In the United States, both the National Hurricane Center and the U.S. Navy’s Joint Typhoon Warning Center use TRMM to reduce risk to lives and property from hurricanes and typhoons.

The primary objection to operating TRMM for an additional two years appears to be financial rather than safety-related. However, your Administration should be able to find a few tens of millions of dollars over the next four years to preserve a key means of improving coastal and maritime safety. A viable funding arrangement can certainly be developed between NASA and the other agencies that use TRMM’s data if you desire it to happen.

I hope that you will intervene to help protect our citizens from the increased risk that would result from a termination of TRMM’s operations this year.
