"Heat Stress In Dairy Calculator" - The software predicts and sets the threshold for heat stress on dairy cows.The software gives accurate diagnoses of weather and heat stress on dairy cows based on:1.
Get regional weather data from the worlds leading weather APIs: Open-meteo.com, Weatherapi.com,...2: Provide heat stress warning according to current weather and solution direction.3: Can accurately calculate the sub-climate of the barn when you provide data to the app4: Can run offline or online by itself5: Data is completely confidential, I do not collect any data.
Using only precise location data to share and interact with weather APIs improves app performance and accuracy.6.
Data analysis based on formulas:THI = 0.8*Tdb+ (RH/100)*(Tdb - 14.4) +46.4; (Mader 2003) (1)Where:Tdb dry bulb air temperature (°C)RH relative air humidity(%)THIadj = 4.51 + THI - (WS*1.992) + (0.0068*SR); (Maderet al 2006)  (2)where:THI:temperature humidity index,V:air velocity, m/sSR:intensity of solar radiation, W/m2Equations to the reduction of heat in barns for dairy cows at different heat stress level with applied cooling system (based on St-Pierre et al.
