Stations improved and excluded from the previous consolidated list

RUSSIAN FEDERATION IN ASIA

  36090 - Improved at the station level. (SLP).



TAJIKISTAN

  38878 - Improved at 700 hPa. (GZ).



IRAQ

  40621 - Improved at the mean sea level. (MSLP).



Stations removed from the previous consolidated list

IRAN, ISLAMIC REPUBLIC OF

  40785 - Although station 40785 still displays positive biases of O-G at the station level, the data were removed from the consolidated list because the biases did not exceed the threshold. (SLP).



AFGHANISTAN

  40942 - No reports during the period.



AFGHANISTAN

  40945 - Although station 40945 still displays negative biases of O-G at the station level, it was removed from the consolidated list because the number of reports (125) was insufficient for quality checking. (SLP).



LAO PEOPLE'S DEMOCRATIC REPUBLIC

  48935 - Although station 48935 still displays positive biases of O-G at the station level, the data were removed from the consolidated list because the biases did not exceed the threshold. (SLP).



CHINA

  51467 - Although station 51467 still displays negative biases of O-G at the station level, it was removed from the consolidated list because the difference between the station elevation and the model elevation (1,007 m) was insufficient for quality checking.
