At the moment we are reprocessing the database with an updated quality control software. If you don't use the ISMN quality control you are not affected. If you do then be advised that in future more observations will be tagged 'dubious' as we are also updating GLDAS supported flags (tags at negative GLDAS soil temperature (D03) and soil moisture rise without GLDAS precipitation (D05)) for the years 2018 - 09/2020. In the individual data-files you will find updated entries in the qflag (quality flag) column.

Further details on the quality control can be found in the preprint of an upcoming 10-year anniversary paper on the ISMN (https://doi.org/10.5194/hess-2021-2).
