      @@GeosearchInternational Dear Andreas, I tried to download the data through a python script that provided in the website of the data, unfortunately, I couldn't as I got syntax errors in the code. Just I was wondering, did you try to download this data? Could you please advise me! Your reply and help will be quite appreciated.

    Hi, Thank you so much for your presentation. Please, how can I access the water surface for specific years and months?

      You are welcome. Yes it is possible, but the only way I have found is via Google Earth Engine. All the best, Andreas

      @@GeosearchInternational Thank you so much Dear Andreas. This information is really important and much needed. We used to invest lot of time to prepare the data (& often leave scope of error) on changing water and get little scope to interpret the reasons behind. By using this database, we can do a lot of good research. Thank you so much again.

      Dear Prof. Biswas, You are right. This dataset is really useful, and powerful to see how rivers and lakes have changed over time. All the best, Andreas

      Hi Irfan,
      May I ask what you need this information for?
      If you want to design solar panels, you could have a look at the Global Solar Atlas: globalsolaratlas.info/map?c=31.056571,12.913991,4&s=48.162396,17.468602&m=site
      If you are interested in evaporation rates, check out my videos on MODIS ET:

      @@GeosearchInternational Hi, Sir,
      very glad to receive your response, Sir I'm working on climate change. I have required net sun hours daily/ monthly data for ETo (evapotranspiration) calculation. Thank you very much.

    • @GeosearchInternational
      @GeosearchInternational  3 года назад +1

      Hi Irfan, for sunshine hours I just use an equation in Excel which is based on the latitude of the location. However, nowadays I go straight to the MODIS evapotranspiration dataset, which is based on the Penman Monteith method and seems to be quite accurate. All the best, Andreas
