Hi, terrascope community and maintainers, I remember that previously, there were various L2 data of TROPOMI under the data directory /data/MTDA/CGS_S5P, which was very convenient for us to process online. However, recently I noticed that earlier data seems to be missing, and only recent data is retained, such as [CGS_S5P_L2_CO]$ ls 2023 2024 2025 2026 [ CGS_S5P_L2_CO]$ pwd /data/MTDA/CGS_S5P/CGS_S5P_L2_CO
Is this due to some specific consideration? Will it be restored in the future? I know Terrascope provides grid-based L3 data, but for some research that requires L2 data, this is far from sufficient. Many thanks for the response.

L2 rolling archive
Hi Cindy, we only keep a smaller, rolling archive of the Sentinel-5P products in order to process our derived L3 products. These L3 products are available for the entire time series.
You can find an overview of these products here: https://docs.terrascope.be/DataProducts/Sentinel-5P/ProductsOverview.html
