For gardeners, growers, forestry or public-safety agencies, golf course manag-
ers, parks departments, and commercial landscape managers, the GroWeather
system (simply referred to as “GroWeather” in this manual) measures environ-
mental conditions which affect plant, pest, and livestock development. This
integrated weather station and data logger measures/calculates, displays, and
stores wind speed and direction, wind run, solar radiation, solar energy, air
temperature, temperature/humidity index and wind chill (apparent tempera-
ture), growing degree-days, soil temperature, humidity, dew-point, leaf wet-
ness, barometric pressure, evapotranspiration, rainfall, and rate of rainfall.
Current readings, high and low readings, cumulative totals, and “daily” aver-
ages are available for display at the push of a button. Degree-day thresholds
(both lower and upper) can be set by the user. The system can sound an alarm
when values exceed a threshold set by the user.
This information enables the grower or turf manager to plant, irrigate, and con-
trol pests with high efficiency. It enables the forester or fire department to mon-
itor fuel and wind conditions. It also gives a measure of environmental stress
on workers and livestock.
