Stations improved and excluded from the previous consolidated list

KAZAKHSTAN

  38232 - The positive bias of O-G at the station level and at the mean sea level has improved since May 2022. (SLP)(MSLP).



Stations removed from the previous consolidated list

TAJIKISTAN

  38836 - Although station 38836 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).



KUWAIT

  40587 - Station 40587 was removed from the consolidated list because observed values of mean sea level pressure were unnaturally constant during the period, and the number of reports (87) was insufficient for quality checking (MSLP).



INDIA

  42295 - Although station 42295 still displays positive biases of O-G at the station level and at 850 hPa, it was removed from the consolidated list because the number of reports (131) was insufficient for quality checking (SLP)(GZ).



NEPAL

  44424 - Although station 44424 showed no particular change in the O-G bias trend at the station level or at 700 hPa, it was removed from the consolidated list because the difference between the station elevation (2,300 m) and JMA’s model elevation (3,315 m) exceeds 1,000 m due to a change from 3,288 m in March 2021 (SLP)(GZ).
