<p class="MsoNormal">I would like to calculate Aridity index base on Hargreaves ETo equation. I use daily maximum and minimum temperature data from 1971 to 2000 and yearly sum precipitation (30 years). The dimension of latitude is (201x464) and the day of year
is (10957) vector for radext_fao56 function. When I run the scipt I get the following error message:<u></u><u></u></p>
