The max on the thermograph read 67ƒF, whereas the mercurial
Max read a high of 73ƒF. This occurrence is common due to
simple reasons. The mercurial max is reset daily at 4 &
5pm (daylight savings and pacific standard times
respectively). Often, the max for the following 12 hour day
is lower than the observation temperature from the day
before. The result is a max representing the observation
time temperature from the previous day. The thermograph, of
course, will show a max indicative of the 12 hour day since
it is on a continuous cycle of measurement. The official max
recorded will be from 24-hour
intervals from the time of observation, therefore, October
26, 1955 recorded 73ƒ, rather than the thermograph’s 67ƒF.

used a Mac Powerbook laptop. Originally their was no real

records on Excel spreadsheets for personal use. One thing
led to another, and ....
Several months later it was apparent I had too much info
entered to keep to myself!! That's when I decided to display
information on the Internet, and began converting the
