Calibration and Validation

Accuracy evaluations and assessments of ALOS products.

ALOS-2


ALOS

Advanced Land Observing Satellite (ALOS, the nickname "Daichi") was successfully launched on January 24, 2006. After the initial mission check, the initial Calibration and Validation (Cal/Val) operation, which involve sensor characterizations, image quality measurements, and accuracy improvement of the standard products, were carried out from May 16 to November 23, 2006.
After the initial Cal/Val operation, JAXA is continuously evaluating the standard products to improve those absolute accuracies. As the results of Cal/Val, the accuracies of standard products processed at JAXA Earth Observation Center (EOC) can be found at
