Thank you, your lessons are very useful and valuable

Hello. How export the result please.

Sir which is more accurate using the SMAP or sentinel 1

I am very happy to see this tutorial as my phd topic is Soil moisture retrieval using microwave RS. It help me a lot... Thank you so much for this wonderful tutorial.😊😊😊❤❤

Sir! GRACE data spatial resolution is 1* X 1* then it will cover how much area? As GLDAS data of 0.25 degree into .25 degree resolution i want to use. But i don't know how to resample the data set as i want do in python but the think is that i resampled the data upto 0.025 into 0.025 degree grid to do grid based analysis is it fine. And if so then how much area is cover by GRACE pre sampling and post sampling, on the same side that about GLDAS dataset? If i resample the data upto 0.5 into 0.5 degree grid size then it will cover how much area?

Hello Amir...Thank you for sharing the amazing tutorial. I have a question for you. In the time 24:11 min, when you show the bands : List (19 elements) I have from the 12 elements, but only some months has the list (19 elements) while others I do not have it. What could be the implication for having or not the 19 elements?

Good job Amirhossein, could CART or Randomforest be used instead of linear regression method?

Can we use mean instead of mode?

thank you for tutorial. Do sentinel-1 dataset (S1_GRD) in GEE need any pre-processing steps like radiometric correction, geometric correction........?

Thank you for the Amazing job you are doing, if you don't mind would you make a Video about Climate scenarios like (RCPs) ..etc.

Thank you for this tutorial, it's very helpful. please add code for analyzing urban growth and correlating with NO2 mean.

Zabardast means brilliantly done.

Thank you so much

Very nice. Plz add for LST and its monthly time series.

❤❤❤ hello too Mr ahrari🎉

Thank you, Amir! You're doing an excellent job. I hope you'll continue your focus on climate-related analysis. I have a question for you: would it be possible for you to provide a tutorial on predicting droughts for the coming years? That would be incredibly helpful.

thanks for the informative tutorial. may I use Landsat images instead of SAR images

Thank you very much for this very explicit and educational video, I learned a lot from you. I don't know if you can share the link to the reference document you used to calculate VCI (seven classes).

لطفا درباره محصولات کشاورزی و موضوعات کشاورزی در سنجش از راه دور بپردازید.

دکتر احراری ، متشکریم متشکریم

I wanted to send the code link of my gee but my comment disappears every time I add the link. I had an error on the code. //Load Area of Nepal var country = ee.FeatureCollection("USDOS/LSIB/2017") var table = country.filter(ee.Filter.eq("COUNTRY_NA","Nepal")) Map.centerObject(table, 6) //Load NASADEM var image = ee.Image("NASA/NASADEM_HGT/001") var elevation = image.select('elevation') Map.addLayer(elevation.clip(table),{},'Elevation') //Elevation above 3600m var elev3600 = elevation.gt(3600) Map.addLayer(elev3600.clip(table).updateMask(elev3600),{},'Elevation3600') //Load Sentinel-2a data and filter by date and region var sentinel2 = ee.ImageCollection("COPERNICUS/S2_SR_HARMONIZED") .filterDate('2022-01-01','2022-12-30') .map(function(img){ var bands = img.select('B.*') var ndwi = bands.normalizedDifference(['B3','B8']).rename('ndwi') var ndwielev3600 = ndwi.updateMask(elev3600) .reproject({ crs: 'EPSG:4326', scale: 500 // Downsample to 500 meters }); return ndwielev3600.copyProperties(img, img.propertyNames()) }) Map.addLayer(sentinel2,{},'Sentinel-2a') // Import OEEL library var oeel=require('users/OEEL/lib:loadAllSF') // Apply Otsu Threshold var otsu = sentinel2.map(function(image) { return oeel.ImageCollection.OtsuThreshold(ee.ImageCollection([image]), 'ndwi'); }).mosaic(); // Combine the thresholded images print(otsu) print( ui.Chart.image.histogram(otsu,table,500) ) var thr = ee.Number(otsu.reduce(ee.Reducer.mean()).reduceRegion({ reducer: ee.Reducer.mean(), geometry:table, scale:500 }).values().get(0)); print ('water body threshold', thr) var water = sentinel2.mean().gt(thr) // Apply threshold to the mean NDWI image Map.addLayer(water.updateMask(water), {palette: 'blue'}, 'Water Bodies')

Can you make video on susceptibility mapping of hazards like landslide, flood etc using machine learning ?

Dear Amirhoussien, Can we use GEE for climate prediction?

Thank you very much for your timely and practical topics. Sir, is it possible to perform precipitation downscaling on 30 years of historical precipitation data? Im want to use it for validation of other models.

Great work......will it be possible for you perform MODIS LST Downscaling From 1 Km to 10m on GEE?

Impressive tutorial. One thing I did not understand is how I can classify different type of crops using this method. The thing I learned is I can only map one crop which is reflecting most energy back, which is showing in red color. My question is How can I map all different crops?

HELLO.... I need to see the changings in coastline by the effect of tidal waves

Love this.. ❤

سلام دکتر احراری خسته نباشید ممنون از اموزش فوق کاربردی شما . جناب دکتر شما ایده ای برای فرونشست داخل ارث انجین دارید ؟ میشه ویدیویی برای این مورد درست کنید

Thank you so much for this fantastic tutorial on ERA-5 Temperature Downscaling using Machine Learning Techniques! Your clear explanations and step-by-step approach made the complex process easy to understand and implement. I've learned a lot, and I appreciate your effort in creating such informative content. Keep up the great work!

this process can do with rainfall downscaling by ERA-5 data?

Can you plz put the reference of methodology so that we can noted for publication

لطفا درباره آتشفشان، آتش سوزی جنگل NBR , بیوماس هم توضیح بدید . منم الان درباره آلودگی صوتی دارم یک مقاله میدم مجبورم با دستگاه نمونه برداری کنم نظر شما چیه جناب دکتر احراری ؟ بعضی جاها ۶۰ دسی بل و بعضی جاها ۸۰ دسی بل هست به نظر شما مقیاس آلودگی صوتی درست هست یا باید دوباره کالیبره کنم تا دقت بالا بره؟

با تشکر از توضیحاتتون اگر بخواهیم برای یک بازه زمانی مشخص lst time series را محاسبه کنیم امکان دارد که به انتهای این کد اضافه شود؟

Thank you for the comprehensive and insightful information provided. Your explanations have been extremely helpful.

Thanks!!!!

THANK YOU SO MUCH AMIRHOSSEIN AHRARI. FIRST TIME IN A DECADE THAT I WATCHED A TUTORIAL IN FULL LENGTH TO CATCH UP WITH A TOOL. VERY WELL ARTICULATED AND PRESENTED. CAN ONE ACCESS A TRANSCRIPT?

First of all, I would like to thank you for sharing these kinds of videos on your RUclips channel. I would like to ask 2 questions to you: 1) First how we can just detect the groundwater information by downscaling the GRACE Data. After downscaling the GRACE data, should we subtract the downscaled version of snow water equivalent, surface runoff, etc. or do we need to follow another path. 2) The second question is, besides the RandomForest technique, which type of machine learning techniques can we use here?

Yet I work on noise pollution 🙏 , فکر کنم خودم یک کد درباره میوه گندم جو دیتکشن انواع محصولات نوشتم براتون میفرستم

How to download the final result in geo tiff?

تشکر 😊😊😊

Very informative. ❤ Can you make a video on crop yields prediction?

Thanks you for all. Please make vidéo on ui app in Gee

Very nice video. Thanks for sharing. I have one question. The image is saved as single geotif file in the drive with different bands how to get image for each month

❤❤❤ please

great work....what if the threshold values is a range within the adjusted histogram .....

Could you upload vedio about NBR fire detection?❤❤❤❤

Thanks, Mr. Ahrari. Is it possible to calculate the snow area with respect to ellevation? Is it possible to mask a covered area by the intended elevation according to the SRTM map?

Sir you are using 55 km spatial resolution data for training by using FLDAS datasets 10 km spatial resolution. If we consider 1 pixel of grace data contains 5 pixels of FLDAS. In training, you are using same 1 pixel value from GRACE for all those 5 FLDAS pixels. If we develop the model like this it will go for over estimation. what do you think sir??

Sir have you written any journal paper related to it. if you have written please provide link
