摘要

The HIRDLS instalment, like any other remote sensor must be able to maintain a high degree of measurement accuracy through its mission life. There are many factors that influence radiometric stability including direct and indirect thermal effects and other aging processes. Ideally the sensor should be capable of 'self-calibrating' and there must be independent methods to track its long term accuracy. For the HIRDLS instrument, being handicapped with regard to 'self-calibration', the high fidelity data available to the ground data processors provide substantive evidence that it has retained good long term 'accuracy'. Details of the long term performance are presented and discussed, together with reference to some problems and their solutions.
