3 September 2008HIRDLS instrument mission performance: an update July 2008
The HIRDLS instrument, 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.
