8), as detected by the
Advanced Scatterometer (ASCAT), a six-beam spaceborne radar instrument designed to measure wind fields over the oceans (Wilson et al.
2010), the European Space Agency
Advanced Scatterometer (ASCAT; C band, 5.2 GHz, 5.8 cm; Figa-Saldana et al.
Many other promising satellites have been launched to acquire global SM contents, such as the
Advanced Scatterometer (ASCAT), Advanced Microwave Scanning Radiometer 2 (AMSR2), and Fengyun [40-48].
These truth data include numerical model output parameters, GPS dropsondes, other satellite data [e.g.,
Advanced Scatterometer (ASCAT), Ocean Satellite (Oceansat)-2 Scatterometer (OSCAT), wind-measuring satellite system (WindSat), Advanced Microwave Scanning Radiometer-2 (AMSR2)], and aircraft-based measurements.
In our case, we merged the Ku-band dB from Quick Scatterometer (QuickSCAT) (2000-09) and C-band dB from
Advanced Scatterometer (ASCAT) (2009-present) using the quantile matching approach.
The wind archives available from scatterometer satellites such as the Quick Scatterometer (QuikSCAT) and
Advanced Scatterometer (ASCAT) provide important global data.
