Comparison of Wind Scatterometers

By JPL convention the SeaWinds instrument flown on the QuikSCAT satellite is termed "QuikSCAT", while the SeaWinds instrument flown on ADEOS2/Midori2 is termed "SeaWinds". The SeaWinds Tandem mission refers to combined QuikSCAT and SeaWinds data during the mission overlap period. The scatterometer mode data from the Earth Resource Mission 1 and 2 Advanced Microwave Instruments are referred to as ERS1 and ERS2 or as ESCAT. The Advanced Scatterometer (ASCAT) is on the ESA Metop-A platform. The scatterometers operating on OceanSat-2 and SCATsat-1 are known as OSCAT1 and OSCAT2, respectively.
