Stations improved and excluded from the previous consolidated list

INDIA

  43226 - The positive bias of O-G at the station level has improved since August 2020. However, low-quality observation data also still appear to have been reported. (SLP).



LAO PEOPLE'S DEMOCRATIC REPUBLIC

  48925 - Improved at the station level. (SLP).



CHINA

  58968 - Improved at the station level. (SLP).



Stations removed from the previous consolidated list

TAJIKISTAN

  38719 - Although station 38719 still displays positive biases of O-G at 700 hPa near the end of this period, the data were removed from the consolidated list because the biases did not exceed the threshold. (GZ).



IRAQ

  40633 - Although station 40633 still displays positive biases of O-G at the mean sea level, it was removed from the consolidated list because the number of reports (116) was insufficient for quality checking. (MSLP).
