The wiki article *Cleaning up old 'bad' data
<https://github.com/weewx/weewx/wiki/Cleaning-up-old-'bad'-data>* is a good
place to get started.
Thinking about it, a very simple way to get rid of all bogus data, is to
simply delete anything before, say, 1-Jan-2000.
You may have to adjust the path to weewx.sdb, and you may have to use sudo:
sqlite3 /var/lib/weewx/weewx.sdb
sqlite> DELETE FROM archive WHERE dateTime < strftime('%s', '2000-01-01');
Then rebuild the daily summaries as per the Wiki article.
Make a backup first.
