We have taken the measurments of temperature, humidity, net radiation and pressure in our lab so we can calculate the potential reference EvapoTranspiration. So to find out the potential reference ET we have the minimum temperature and maximum temperature of each half an hour. same for humidity. My question is to find out ET per day, should I take the mean of minimums or the minimum of all? I have the same question for maximums. per day and per month. Thanks.

  • $\begingroup$ Funny. I'll try for a simpler title.. $\endgroup$ – Tessnim Jul 22 at 15:59
  • $\begingroup$ In relation to what? What do you mean by "better?" If you want the daily maximum (or mean or minimum) ET, you need to calculate it for the entire day, and apply your desired statistical function. $\endgroup$ – BarocliniCplusplus Jul 22 at 18:43
  • $\begingroup$ Simce this is mostly a statistics question, it might help if you provide the formula you're plugging the minimum and maximum temperatures into. Are daily / seasonal cycles being represented? $\endgroup$ – Spencer Jul 23 at 22:44
