    Hi Mikhail. Thanks for your videos and for the code. Could you give your opinion on the new OpenET CONUS evapotranspiration datasets available in GEE?

    Thank you so much. currently on my introductory courses to GEE. However, Would it be possible to streamline this data to specific states within a country?

    Thank you very much! Extraordinary tutorial! It it possible to get the result in geoTiff format?Dear sir, can we use the result for publication? Its reliability for scientific paper?

    How do you change the date range for the MODIS 500km product?

    Hi, thank you for the video, do you also have a script for daily PET? or and suggestion, I need a higher resolution than monthly. Thanks

    Hi Mikhail, It was a very useful and informative script. However, I couldn't get what is the third parameter in the product list? It seems that the values are relevant to the spatial resolution of the product. But, there is a mismatch. For example, for MOD16A2, the scale parameter is 1000, while the spatial resolution is 500. I appreciate it if you could resolve this ambiguity.

    • @MikhailSmilovic

      Hi Somayeh, you're right; the spatial resolution is 500. In the script, at line 112, where the spatial resolution for MOD16A2.006 is input, scale=500, so this is correct. ET_Sources was showing 1000, however, and this has now been corrected; thank you for pointing this out! Currently, the script doesn't use ET_Source, and it acts only as a summary table. Ideally, someone could edit the script to loop through this list :)

    Hi from Chile, How do I quantify snow melt based on modis snow covered area for a time series?I try to do it for a year.

    I appreciate the valuable information. Can you please link a script to extract daily values, if there are any? cheers

      The script "TRMM_daily-from-3hourly" in github.com/mikhailsmilovic/Earth-Engine, extracts the daily mean from the 3-hourly dataset

    Guten Tag Mikhail, thank you very much for your videos. I will like to ask if you have a script that will help extract monthly TRMM datasets for regions. Thank you very much.

      Guten Tag Mariam,
      Here it is updated for TRMM 3B43: Monthly Estimates:
      code.earthengine.google.com/73b3512296d32911c68ae252d68a7da7
      Script on GitHub: github.com/mikhailsmilovic/Earth-Engine/blob/main/TRMM_monthly
      One could tailor the above script for any input, by changing five parts:
      1. Collection name,
      2. Scaling/(number of days in unit),
      3. Band name,
      4. Scale,
      5. Title
