| Description | This dataset provides browse images of the NASA Scatterometer (NSCAT) Level 3 daily gridded ocean wind vectors, which are provided at 0.5 degree spatial resolution for ascending and descending passes; wind vectors are averaged at points where adjacent passes overlap. This is the most up-to-date version, which designates the final phase of calibration, validation and science data processing, which was completed in November of 1998, on behalf of the JPL NSCAT Project; wind vectors are processed using the NSCAT-2 geophysical model function. Information and access to the Level 3 source data used to generate these browse images may be accessed at: http://podaac.jpl.nasa.gov/dataset/NSCAT%20LEVEL%203. |

| Platform/Sensor | ADEOS-I / Platform Name: Advanced Earth Observing Satellite-I (ADEOS-I) Orbit Period: 100.92 minutes Inclination Angle: 98.59 degrees Ascending Node: 1996-Sep-14 22:20:33 NSCAT SENSOR Name: NASA Scatterometer (NSCAT) Swath Width: 1600 km Description: Every two days, under all weather and cloud conditions, NSCAT measured wind speeds and directions over at least 90% of the Earth's ice-free oceans. NSCAT used six antenna beams to scan two wide bands of ocean, one on each side of the instrument's orbital path. NSCAT transmited short pulses of microwave energy to probe ocean surfaces and then measured the reflected or backscattered power. Variations in the magnitude of this backscattered power are caused by changes in small (centimeter-sized), wind-driven waves. Using a method called Doppler processing, the measured backscattered power was separated into cells at specific locations on Earth's surface. |
