TRMM Satellite Altitude to be Raised to 400km (Aug. 6, 2001)
TRMM completed its nominal three year mission in January 2001, and is continuing to operate. Based NASA's latest mission analysis,
TRMM lifetime will be 1.5 years shorter than the previous estimate. NASDA and NASA decided to raise the satellite altitude to 400 km in order to extend its lifetime.
Standard algorithms require several modifications for operation at 400 km altitude, and TRMM standard products will not be available during
the modifications. Standard products during this term will be processed after the data release. The current boost plan and data delivery schedule are shown below.
