Hi @bne . Your station is located in Cyrus where our CL system does not have enough comparison ground truth data to form a baseline in-situ calibration curve. Thus the CL system has not applied a tweak to your humidity yet. However, we doubt your high humidity is related to the CL system.
Instead, we suspect it is related to a known issue with prolonged high humidity exposure. Please see this thread: https://community.tempest.earth/t/humidity-appears-incorrect-solved/402/425
