3. Quality information per product

In this section it is plotted some information contained in the Quality Summary data set of
the level 2 products. Only products in dark limb conditions and without errors (error flag in
the MPH set to "0") are used.

 

3.1 Plot quality information per product (time dependant)

3.2 Plot quality information per product (world map)

4. Level 1 quality information per product

In this section it is plotted some information contained in the Quality Summary data set of
the level 2 products that comes from the level 1b processsing. Products without errors (error flag in
the MPH set to "0") are used.

4.1 Plot quality information per product (time dependant) comming from level 1b processing

4.1.1 Plot level 1 quality information per product (time dependant): ENVISAT ASCENDING passes

4.1.2 Plot level 1 quality information per product (time dependant): ENVISAT DESCENDING passes

!Warning: No products without errors in descending found

4.2 Plot quality information per product comming from level 1b processing (world map)

4.2.1 Plot level 1 quality information per product (world map): ENVISAT ASCENDING passes

4.2.2 Plot level 1 quality information per product (world map): ENVISAT DESCENDING passes

!Warning: No products without errors in descending found

5. Trace gas profiles

5.1 Ozone statistics based on quality of products

The final quality of the products can be "measured" using the STD (Standard Deviation) attached to every point profile.
This information is written to the parameter GOM_NL__2P/NL_LOCAL_SPECIES_DENSITY/o3_std of the level 2 products. The table
below shows the statistics for given STD ranges.

The statistics are given with respect to the overall valid production:
- Products without fatal errors: GOM_NL__2P/MPH/PRODUCT_ERR=0
- Valid point profile: GOM_NL__2P/NL_LOCAL_SPECIES_DENSITY/pcd(0)=0

The 'Criteria' is applied to valid points of dark limb products:
- Products in dark limb illumination condition: GOM_NL__2P/NL_SUMMARY_QUALITY/obs_ill_cond=0
- Products without fatal errors: GOM_NL__2P/MPH/PRODUCT_ERR=0
- Valid point profile: GOM_NL__2P/NL_LOCAL_SPECIES_DENSITY/pcd(0)=0

So, the table below shows the percentage of dark limb and valid observations for each criteria with respect
to the overall valid daily observations.

5.4 Plot ozone profiles where STD < 10% (dark without errors)

The colorbar represents the latitude.

qds_image

5.5 Plot ozone profiles where STD < 5% (dark without errors)

The colorbar represents the latitude.

5.7 Plot NO3 profiles for all STD (dark without errors)

The colorbar represents the latitude.
