Activity description

The goal of TUNER is to provide a complete and consistent data characterization in terms of uncertainty, resolution and content of a priori information, for the largest possible number of space-borne temperature and composition sounders. Specic objectives are:

  1. An inventory of the error estimation tools used by past and current satellite missions will be made. The same applies to tools for resolution estimates and a priori content.
  2. The used tools will be assessed for consistency and completeness.
  3. Strategies will be dened to complete the error estimates and to make them consistent.
  4. Missing error and resolution estimates will be provided for the most important data.
  5. Recommendations on the use of the error estimates will be established for each instrument.

Published results

A TUNER special issue is open for submissions in Atmospheric Measurement Techniques.
