@Eng.Shihabalbalushi, I have been using ESRI ArcView/ArcGIS since 1999, but nowadays I use exclusively QGIS because it is all I need... so my GIS videos are only for QGIS. Regarding ET data I'm using MODIS ET/PET with 500m resolution. Normally I get the time series since 01/01/2000 - see: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cUAtYyGI9mI.html. I'm also going to start using FAO WaPOR, since they expanded the dataset to Asia. What exactly do you need to do? Make a map of ET? All the best, Andreas
