# On-site weather from 15 February 2024 onward

All earlier measurements, including 14 February 2024, are excluded. Lufft WS500 and Vaisala WXT536 remain separate. Original online UTC clocks, Europe/Sofia conversion, accepted minute values, daily/hourly quality thresholds and circular wind-direction definitions are unchanged. Missing data are not filled. Annual/monthly statistics were recalculated from the retained minute exports; sample SD describes measurement spread. Published source-row audit tables from the former period are not reused. Original archives remain private and unchanged.
