Interpolation in CDT – Email Extracts (2022)

Interpolation in CDT (Email Extracts) 2022 Dear Dr, I have produced maps of  total rainfall for the past 8 days  ( 27- 07-2022 to 03-08-2022) for Met stations and Hydro catchment areas in Sri lanka. I couldn't find a way to plot the total rainfall of weekly data (or 8 days). Because, CDT has given the facility to take summary statistics and spatial analysis for dekadal, monthly, seasonal, annual data etc. Therefore, I used "aggregation time series- moving windows' '. Then I set the aggregation function as Sum and the rolling window as 8. After that, I was able to get the total rainfall of 8 days which shows the cumulative value on the 8th day. I visualized the last day since it shows the total rainfall while other days show as blanked. Following are those files which show total rainfall.
