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.

[@amirhosseinahrarigee]

Yes you can extend your model for a longer period of time.

Good day Sir, I have several questions. I didn't find better source than your channel in this area, so would be glad if u help me. I want to get sea surface temperature map using Landsat 8 dataset, but I got confused which dataset I should use. I have done some research and here are my thoughts: 1. Using raw images. In that case I should convert DN values to TOA radiance first, after that atmospheric correction should be applied with equation that involves upwelling, downwelling, atmospheric transmissivity and emissivity parameters. Then water surface temperature can be calculated using another equation (that involves K1, K2). In this method I don't understand one part. Parameters for atmospheric correction should be obtained from Landsat level 2 dataset, however this dataset is mostly used for land surface temperature analysis. So is it correct to get these parameters from level 2 dataset? 2.Can I use Landsat 8 TOA dataset and in that case do I need to go through all these above steps like DN to TOA conversion, atmospheric correction and getting temperature or is it already processed dataset? Is it level 1 or level 2 dataset? 3. Can Landsat 8 level 2 dataset be used for SST mapping or is it used just for LST mapping? Please give your suggestions, Thanks for great content

[@amirhosseinahrarigee]

thanks for the comment. Landsat LST band is already available and no need to manual calculation. You can find the LST band under collection 2 level 2 data.

Fascinating!!

thanks for your following.

[@user-rb1fr7ob5j]

When you type in a code, you automatically have choices to choose from. For example, you write: var lc = imageCollection2.mode.sel and you get a list of function options. I do not have such a list when typing the code. Could you please tell me how to enable this option?

[@amirhosseinahrarigee]

Yes, when you are writing, press ctrl+space to see the codes. It is working on windows and Mac.

Is it possible to reduce landsat 30m into 10m using GEE;; please share related code lik sir- my request

[@amirhosseinahrarigee]

Yes it is possible but I haven't try yet.
