[weewx-user] Re: update barometric pressure statistics in weewx 3.1.0
Thanks for tip, Gary. I ran wee_config_database —drop-daily and saw this evidence in the log on weewxd startup: Sep 8 21:05:39 seal weewx[14232]: engine: Starting backfill of daily summaries Sep 8 21:12:27 seal weewx[14232]: engine: Processed 1116765 records to backfill 1631 day summaries in 408.15 seconds but it did not pick up my new drastically lower pressure. Then I realized the statistics are actually on pressure, not the barometer reading. I might be putting the reading from my pressure sensor in the wrong field. Again, in the short term, I fabricated pressure readings by finding a suitable linear adjustment to convert barometer to pressure from nearby readings with both, and updated the archive table where pressure was NULL for the three emergency readings: update archive set pressure = 0.992657*barometer where dateTime between 1567895340 and 1567905540; Then dropped the summaries again, and restarted weewxd. The statistics page now shows my new all time low *pressure*. I wouldn't say science has marched on. That will have to wait for our next hurricane.
