Latest news on validation - August 2003
An error in Level 2 pre-processor has been detected by BOMEM in the computation of the Instrument Line Shape (ILS). This error has been proved to be the cause of the error in the AILS width detected during the Commissioning Phase. A short-term correction will be implemented soon.
Further details can be found here
Current investigations are dedicated to the non-linearity correction (probably related to the oscillations detected in retrieved profiles).
The following strategy has been defined by ESA:
The Near Real Time processor must remain 'as is' in terms of computing time. Improvements in the data due to new convergence criteria and extended range (see July 2003 activity) will not be implemented since these require additional computing time. Short-term correction of the bug in the computation of the ILS will be implemented.
The Off-line processor will take care of the product quality, a new auxiliary data set that allows:
will be used soon.

The Off-line processor will take care of the product quality, a new auxiliary data set that allows:
- full retrieval range extension down to 6 km;
- improved convergence;
- short-term correction of the bug in the computation of the ILS.
