Stations improved and excluded from the previous consolidated list

IRAN, ISLAMIC REPUBLIC OF

  40700 - Since the station's elevation above sea level was changed from 32 to 78 m in September 2021 in JMA's records based on OSCAR/Surface, the negative bias of O-G at the station level has improved. (SLP)



IRAN, ISLAMIC REPUBLIC OF

  40713 - Since the station's elevation above sea level was changed from 1478 to 1344 m in September 2021 in JMA's records based on OSCAR/Surface, the positive bias of O-G at the station level has improved. (SLP)



IRAN, ISLAMIC REPUBLIC OF

  40741 - Since the station's elevation above sea level was changed from 235 to 278 m in September 2021 in JMA's records based on OSCAR/Surface, the negative bias of O-G at the station level has improved. (SLP)



IRAN, ISLAMIC REPUBLIC OF

  40854 - Since the station's elevation above sea level was changed from 940 to 1067 m in September 2021 in JMA's records based on OSCAR/Surface, the negative bias of O-G at the station level has improved. (SLP)



IRAN, ISLAMIC REPUBLIC OF

  40877 - Since the station's elevation above sea level was changed from 470 to 499 m in September 2021 in JMA's records based on OSCAR/Surface, the negative bias of O-G at the station level has improved. (SLP)



VIET NAM

  48802 - The negative bias of O-G at 850 hPa has improved since April 2021. (SLP)(GZ).



Stations removed from the previous consolidated list

TAJIKISTAN

  38719 - Although station 38719 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).
