In this video I will be teaching you how to organize your required inputs in Excel and feed them into R studio to calculate the Potential Evapotranspiration values.
Hello .I really find it good but I just need a help how u have used 28.78° as latitude bcoz its always in any range I want to know it plz help. I would like to hear back
How do I test for best fit using AIC BIC Wilks AD test for different distribution parameter I.e gamma gumbel etc for different time scale for multiple stations ?
bro that package has an error computing etp by hargreave's method cuz if u try it using just an spreadsheet in excel the results will be different and will not have anything related with the results obtained in R by the SPEI package.
Hi. thank you for this well explained tutorial . I faced with a problem using penman function . I have all the data in the code that I send here.my code is : penman(data$Tmin,data$Tmax,data$U2,lat = 36.26,data$tsun,data$RH,z = 1213,crop = 'short') but when I run it this error appears : Error in penman ( data $Tmin , data $Tmax, data$U2, la t = 36.26, data $tsun , : object 'm le n' not found In addition: Warning message: In penman(data $Tmin , data $Tmax, data$U2, la t = 36.26, data $tsun , : Using user-provided (Ra) can you tell me which part did I wrong and what is the meaning of this error. thanks
Thank you for this helpful video. I have 2 questions. What is the difference between Penman and Penman Monteith method for calculating potantial evapotranspiration? And can we calculate pot. evapotranspiration in R Studio using P. Monteith Method?
Hey there, we can calculate PET in R studio with P. Monteith Method as too by using the function "penman" in the SEI package. Since I did not have the data for the wind speed , so i did not use it in the video, but if you do have you can try it out. As for the difference between Penman and Penman Monteith methods, do check it out here: www.fao.org/3/x0490e/x0490e06.htm Thank you :D
