ATTENTION: Degraded GOME-2A Level 1 product quality The solar eclipse in northern hemisphere has significantly affected the signal levels of the GOME-2 daily solar calibration from Metop-A (M02). Consequently GOME-2A Level 1 product quality was degraded between sensing times 11/08/2018 10:28 UTC - 12/08/2018 11:48 UTC and has affected the quality of retrieved Level 2 total NO2. |
TOP STORY: AC SAF GOME-2 aerosol product upgraded
The upgrade was successfully completed on Monday 13th August 2018.
The new version of the AAI product from the PMDs is now corrected for the so called end-of-orbit and across-track corrections. Please, see ATBD at . An example is below. It clearly snows that the east side of the swath near the southern edge of the orbit is no longer strongly affected by increased values. Also, the parabolic pattern that was visible in the cross track direction has been flattened out, showing a much more homogeneous pattern.
