Hi
Our project is located outside the US and so we're applying the FAO ETo calculator: http://www.fao.org/land-water/databases-and-software/eto-calculator/en/.
I found the ETo calculator provides results as daily ETo (mm/day) and not as monthly ETo (mm/month) as per the LEED 'Baseline Calculation' tab in the LEED v4 Outdoor Water Use Reduction Calculator. How did you convert this to monthly rates? Is it as straight forward as multiplying by number of days per month?
Thanks
Priscilla Joseph

Dear Senna,
You can also use IWMI (International Water Management Institute) to get the ETo data in mm/day.
Following is the link for the website :
http://wcatlas.iwmi.org/
You have to make an account first, and then after log in you can input the longitude and latitude of your project to get the ETo data (mm/day).
Thanks and regards.
