Calculation of the average daily temperature 17:36

17:36

A common way to calculate average daily temperature is to take the sum of the daily maximum and daily minimum temperatures, and to divide by two. A better statistical approximation of the average temperature is to take measurements made every hour and then to find the mean value of those continuous measurements. This blog post shows a comparison of…

Constants in the turfgrass growth potential equation 24:05

6M ago24:05

24:05

The PACE Turf growth potential equation has one variable (the actual air temperature) and two constants. The constants are optimum air temperature and a term for variance that controls the shape of the curve as the actual temperature moves away from the optimum temperature. It's a little more complicated than that, because the constants change depe…
