NASA TRMM -- Rainfall in Nadine (IMAGE) NASA/Goddard Space Flight Center Caption NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Tropical Storm Nadine on Sept. 12 at 1006 UTC (6:06 a.m. EDT) and captured rainfall rates occurring in the storm. The image was a combination visible/infrared image derived from TRMM's Visible and InfraRed Scanner (VIRS) instrument and TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. Most of the tropical storm had light to moderate rainfall (green and orange), falling at a rate between .78 to 1.57 inches/20 to 40 mm per hour. The red areas (in the southeastern quadrant) indicate heavy rain falling at a rate of 2 inches/50 mm per hour (red). Dark red indicates very heavy rainfall at a rate of 50 to 74 mm (2 to 3 inches) per hour.
