| Description: | A problem related to the instruments ability to successfully acquire the Sun, which later
prompted the removal of the instrument for refurbishment, started to develop during this
time period.
The data acquired and passed through the regular aeronet data quality checking routines is
probably o.k., but should be used with caution. |
| Suggestions: | Data during this time should be given less weight in your analysis. |
