Q
Some limitations of ARNP
A
In Aerosol product (ARNP) of Ver.3, we confirmed that some problem.
-
-----
- Some tiles products in ocean area are stored as all fill data.
- There are some products for which some data is not created / minor value discrepancies occurs.
- Image_end_time is after UTC 23:30
- Descending orbit (daytime observation)
- Tile list (Tile number and locations are shown in the figure)
- File name list (2021)
- In addition, some global (ARNPF) data may be affected.
- Snow and ice areas are not masked in L3 global data. The cause was that the input L2 ARNPF mask for statistics was an invalid value.
- Some L2 and L3 global data with wrong values is generated due to the Incorrect input data.
