Hi @Highzik
I think you can try loading the rainfall data into the raindata array in MATLAB Workspace.
filename = 'rainfall.xlsx';
raindata = importdata(filename);
You can also try creating a table from the Excel file, so that you can looking into the displayed data in tabular form.
raintable = readtable(filename)
Next, try providing the formulas for average rain rate, rain attenuation and rainfall trends.
