I have 62 years of monthly rainfall and temperature data. The problem is that I have a lot of missing values. I would like to use the IDW method to fill them. Could you please tell how to do it?
You have the data in maps or in tabular form? If you have the data in maps, What I would have is to create a dense point network over your image, extract the values of your desired variable, and finally create an interpolated surface in the entire area using the IDW method. Once you have this done, then you should clip the area where the original missing data were placed, and "paste" the interpolated surface (only in the missing data area).
I hope this can help you. If you need more help, please feel free to contact me.
I have 24years rainfall data with missing data in some months , my data are in tabular form , i want to use IDW, how this is done to fill the missing data
As Dr.Cuesta said, use ARCGIS and interpolate your data using IDW or kriging. Then, you can have the missing values.
you can visit my "GitHub"

Do you think if maybe there is better than IDW to find this values ? this is my interest
