I have no experience with the La Crosse weather instruments. I used
Peet Brothers instruments for several years, but each of two anemometers
failed after only a couple years. I replaced them with a Davis weather
station. It has functioned without failure and the software stores data
Neither was of certifiable accuracy. I chuckle at reports of
temperature to a tenth of a degree, of barometric pressure to a
thousandth of an inch, or of rainfall to a hundredth of an inch.
It is important to mount the instruments in accordance with accepted
measuring standards if one wishes to compare the data with that of
standard weather stations. For example, the temperature sensor must be
1.5 meters above grass and shielded from direct solar radiation. The
anemometer must be 10 meters above earth and at prescribed minimum
distances from structures and other disturbing features. A Google
search should locate the international standards for these rules.
An amateur may not be able to comply with all the rules, but should know
what the deviations are and should state them when sharing data with others.
