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 ?!
Thank you for you presentation! How can I correct 400 point of global data by using five observation data average it may wind, Rf, Temperature, RH and SD!!? Note csv or excel file format
This program is only for daily data... There are some other softwares that can do bias correction of monthly datasets but unfortunately those are not freely available..🌹

@@yaoli1413 you can download CMIP6 data, by following the tutorial video I have uploaded earlier, you can choose the type of downscaling (dynamic or statistical) after the data download
Hello This video is very helpful ! Thank you for this Im usine text files format to do the biais corrections When I try to upload them into the CmHyd it doesnt recognize them Do you have any explaination ?
Can we use it for cordex data with rotated cordinate system? Another one, unit of precipitation in cordex data is something different can we use it for that also
I taken historical data 1951 to 2014 , observe data is 1971 to 2014 and future data is 2015 to 2100 . I am facing difficulty in when i am used linear scaling , power transformation , local intensity it shows data 1951 to 2100 ..bhut delta change its extraction the file to much missing data .how can solve it
You can do multiple type of downscaling using this software, such as Distribution Mapping, Linear Scaling, Delta Change Correction, Variance Scaling, Power Transformation, Local intensity Scaling etc
thanks enginer haron but my question is after downloading historical and future data for like rcp then how to prepare file for using it in cmhyd software?????
If you are interested in discussing how I did this, lets try to find a place where we can message each other or video chat. Here is hard to describe my process of doing this overlap that you are having difficulty with.
Thanks about ur good tutorial, but here i got a question about "if our data (both observed and GCM) is monthly and that is not daily data, is this possible to use this software for monthly data?
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?
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.
Nice video. However i have prepared my data accordingly but upon uploading the location file, the software returns this error every time. What could be the problem?

Hi Haroon, thank you so much for the video. Is it possible for you to show us how to do a cmip6 downscaling and bias correction using R? Thanks.
did u find anything for dwonlscaling?
Do this software works for downscaling and biascorrection of the CMIP6 dataset?
Yes, it will work for CMIP6 also but for that you need to use data in text format instead of nc format...🌹🌹🌹
Which folder contains the bias corrected, observed and historical raw values of a parameter.

Some SSP can be supported but you can use it for CMIP5 data.

great work engineer, but can you brief on CORDEX cmip6 data please?
Is this possible to use CMIP6 with CMhyd ?
All the CMIP6 models are not fit with cmhyd but some of them can.

CMHyd was primarily created for bias correction of CORDEX data. Yes, it can be used with rotated coordinate system.
