Abstract
A method for cross calibration of the mission instruments onboard same platform as well as a method for cross validation of the products derived from more than two mission instrument data are proposed. The methods are verified with the mission instruments onboard ADEOS satellite. The experimental results from cross calibration betwee OCTS and AVNIR show that better than 1.5% of caross calibration accuracy can be achieved while the cross calibration between ADEOS/TOMS and Earth Probe/TOMS shows that better than 1% of cross calibration accuracy can be achieved. On the other hand, the cross validation of wind vectors derived from ADEOS/NSCAT and ERS-2/AMI shows that better than 0.41 m/s of cross validation accuracy can be achieved while the cross validation of Sea Surface Temperature derived from OCTS and AVHRR shows around 5 K of systematic difference between them. Through these studies, it was found that improvements on the data quality and on the calibration accuracy can be achieved.
