Sept. 18, 2008: NASA's TRMM Satellite Assesses Hurricane Ike's Rainfall
Hurricane Ike was a huge rainmaker throughout the central U.S. from the time it made landfall until it zipped into Canada. This image depicted a complete history of Hurricane Ike rainfall, from when it was named on Sept. 1, 2008, through Sept. 15, 2008.
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has been measuring rainfall from space ever since it was launched in November 1997. TRMM has been invaluable in helping forecasters peer into storms to see rainfall, and determine how much rain has fallen over areas, assisting in flood forecasting.
Only rainfall data attributed to Hurricane Ike were used in the TRMM calibrated rainfall analysis. Merged rainfall Data (3B42) from TRMM, other NASA satellites, U.S. Department of Defense satellites, National Oceanic and Atmospheric Administration polar-orbiting satellites, and geostationary satellites were used in the analysis.
