Spectral Instrument Design Modelling

What is it about?

A spectral performance model, designed to simulate the system spectral throughput for 21-channels in the High Resolution Dynamics Limb Sounder (HIRDLS) radiometer for Earth satellite monitoring is described.

Why is it important?

This model uses the measured spectral characteristics of each of the components in the optical train, appropriately corrected for their optical environment, to determine the end-to-end spectral throughput pro®le for each channel.

The optical arrangement and spectral design requirements for fltering in the HIRDLS instrument are described together with a presentation of the performance achieved for the complete set of manufactured flters. Compliance of the predicted passband throughput model to the spectral positioning requirements of the instrument is also demonstrated.
