Stations improved and excluded from the previous consolidated list

CHINA

  52866 - Since the station's elevation above sea level was changed from 2296 to 2435 m in December 2019 in JMA's records based on OSCAR/Surface, the negative bias of O-G at the station level has improved. (SLP)



CHINA

  54027 - Since the station's elevation above sea level was changed from 485 to 589 m in December 2019 in JMA's records based on OSCAR/Surface, the negative bias of O-G at the station level has improved. (SLP)



Stations removed from the previous consolidated list

TAJIKISTAN

  38947 - Although station 38947 still displays negative biases of O-G at the station level, it was removed from the consolidated list because the biases did not exceed the threshold. (SLP)



OMAN

  41263 - No reports during the period



OMAN

  41265 - Directorate General of Meteorology, Oman informed us the correct barometer height at this station. Therefore it was removed from the consolidated list.
