How to use Earth Engine for Evapotranspiration, from daily & hourly to monthly (6 products)

We extract Evapotranspiration (ET) time series from global products available on Google Earth Engine by uploading a shape file and running the script provided below. The script produces time series of monthly mean daily Evapotranspiration for six globally available ET products on Earth Engine.
Script: code.earthengi...

Hello and thank you dear teacher. You are one of the unique and your way of explaining and teaching is very calm and unique.

[@MikhailSmilovic]

my pleasure 💚 thank you for your kind words

[@Silnita]

Thank you very much !! I think I love you. These videos are so helpful.

[@MikhailSmilovic]

My pleasure; glad you are finding these useful. If you have any suggestions for the scripts, let me know 💙

[@hamedpoorsepahysamian8359]

Great and very informative. Thank you very much for the videos.

[@christianbouix1015]

Helped me a lot! Thank you man

[@MikhailSmilovic]

Awesome 😎

[@mariamidowu9708]

Thank you very much. I look forward to more videos from you. It was very helpful.

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

[@EmmanuelEzeh-q7c]

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?

[@MikhailSmilovic]

My pleasure 🎉 With shapefiles for the different states, one could run the script for each

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.

[@cusco4x295]

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?

[@nozimteshaev4661]

thank you sir.

Our pleasure, thank you💧

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

[@alemayehumullatuadashio5350]

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?

[@MikhailSmilovic]

Just finished a tutorial on exporting GRACE satellite data for a region of interest in tiff format 🌍 let me know if this helps kzbin.info/www/bejne/Y3LGnZJ3nruXg9U Each Earth Engine products have a Citations tab on the webpages describing the datasets. If these citations are reliable and published, then this should be perfectly fine for an investigation of our own 👩‍🔬️

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 :)

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.

[@MikhailSmilovic]

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

[@mariamidowu9708]

@@MikhailSmilovic Thank you very much Mikhail. You rock👍

[@tewodrostilahun9879]

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

[@MikhailSmilovic]

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