    Sir few doubts here,
    1. the historical data and future data of GCM is taken for which location? generally GCM data is downloaded for a particular grid point. in this video which location GCM data has been downloaded?
    2.where can I get the mathematical details (technical document of CMhyd) how the downscaling calculations will be done for various methods, because that details have to be explained in case of thesis submission.
    could you please help ?!

    Is this Bias correction or downscaling? If it is downscaling, where is the changed resolution.? How could you change the coarser resolution of the GCM into a fine resolution?

    • @EngrHaroonHaider
      @EngrHaroonHaider  Рік тому

      By employing this method, we can transform gridded data into point data; however, bias correction does not involve altering the resolution. This software rectifies the data, utilizing both historical and observed station data.
