The Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E), onboard NASAs Aqua spacecraft, began sending high quality data on June 1, 2002. Initial (uncalibrated) data gathered from the AMSR-E has delivered impressive pictures of the planet's sea brightness temperatures from the 89.0 GHz vertical and horizontal polarization channels and the 23.8 GHz vertical polarization channel, averaged over the 3-day period June 2-4, 2002.
