MIPAS Data Quality - Lessons Learned

Gottfried Schwarz(1) and Siegfried Hilgers(1)

Abstract

The MIPAS instrument flown on Envisat has delivered an enormous amount of binary data. From these instrument data higher level products have been derived routinely.

While the scientific community hopes for geophysical products of highest quality, a number of technical constraints, atmospheric conditions and calibration uncertainties can limit the usefulness of some data products. Typical limitations range from data availability to geometric and radiometric accuracy.

After some years in orbit, a number of potential pitfalls is known today. We will outline how the data quality of MIPAS products can be monitored and how to circumvent the use of questionable products.

Our results will be presented mostly in tabular form allowing a direct comparison with other instruments and their products and we will conclude with an outlook on the potential gain of product re-processing.
