Dry deposition of sea salt aerosol (both small, medium and large particle sizes) variables appear to not have trustful data after October 2020. Have there been any updates since then? Is there an alternative dataset containing dry deposition of sea salt aerosols?

Could you share details on why the data are not trustful?  
Thanks

Since October 2020, values seems to be consistently considerably lower than before. I have not save the values from 2018 (only a part of 2018 is available from your side), but otherwise, 2018 seems to be consistent with 2019. Could you please clarify?

Hi again! Since I have not heard from ECMWF team since October, I would like to follow up on the above question. Could you please look into it?
