We finished updating the ISMN quality flags in the database. If you don't use the ISMN quality flags (see example below) you are not affected. If you do then be advised that compared to previously more observations are tagged 'dubious' as also  GLDAS flags (tags at negative GLDAS soil temperature (D03) and soil moisture rise without GLDAS precipitation (D05)) for the years 2018 - 09/2020 are included.

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) and in our forum.
