Weather Observations into Journey North
Using the Weather Observation Chart
Pick a time to take your readings. Collect them the same time each day.
Decide how you will collect them on the weekends.
- A good
minimum/maximum thermometer will record the highest and lowest temperatures
since your last reading. Thermometers are available in battery-powered
digital form, standard mercury/alcohol or more expensive remote sensing
and recording units. If choosing standard unit, look for one that
uses mercury for the maximum reading and alcohol for the minimum.
collect the most accurate information your thermometer should be located
outside in a safe, sturdy location on the north side of the building
where it's shadiest. Position it securely beside the building, perhaps
on a brick foundation and 5 feet off the ground for the most accurate
reading. To match the readings taken by the National Weather Service
the thermometer should be located over turf.
barometric pressure should be recorded several times a day for the
most accurate weather predictions.
pressure readings for a 24 hour period in your area are at AccuWeather.com.
