CROSS-CALIBRATION AND VALIDATION OF JASON-1 AND T/P ALTIMETRIC DATA IN THEIR SYNCHRONOUS CYCLES
|
Abstract:
The significant wave height,backscatter coefficient,geophysical corrections and corrected sea surface height of two version of Jason-1 data are compared with synchronous T/P data based on collinear method.Single satellite crossover differences of Jason-1 to T/P are also calculated and compared.The results show that Jason-1 altimetric data have the equivalent accuracy with T/P,so it can be a good substitute of T/P and realize the first 20 year period observations together.
