I am trying to get information about potential evapotranspiration for the south of Ecuador, however, until the moment all the sources visited are monthly, or daily but with poor resolution.
Potential evapotranspiration is a bit difficult to get because it depends on the available water. Why don't you use what is available and mention that as the limitation of the data.
You can find some good and free source of evapotranspiration daily data in the web of the country, moreover, you can get it from satellite.
What about the Giovanni website for satellite data, did you try it before?

Please see and enter this link to download meteorological data. For water requirement calculation and irrigation scheduling
you can used https://power.larc.nasa.gov/
You calculate ET based on temperature and rainfall data. Use the Hargievs method. R software can also be used to execute number of other evaporator models.
Hi dear Gonzalo.
I think, if you use data base ECMWF version ERA5 or ERA_Interim it's maybe useful. I recomending version ERA_5 for you're studies. In this data base, you can data donloading with different format (e.g Net CDF, GRIB), but one thing is very important, that's it spatial and temporal resulation data. In the version ERA_Interim, users can donloading data with different spatial resulation but in ERA5 isn't these option. In the other hand, with ERA_5 version, you can downloading multiple variable into one file, and maybe best advantage it's.
Dear Gonzalo, if you been have problem with database, you can call me through skype or send me emaill.
Dear Gonzalo,
You can use the daily global potential evapotranspiration (PET) calculated from climate parameter data that is extracted from the Global Data Assimilation System (GDAS).

Hi dear Gonzalo.
For you're answer question, I recomendation Earth Data. In the database you can downloading with different formats.
