I have several netcdf files, which I have opened with xarray. They contain daily data from 1950 to date. What I want to do is to calculate the intramonthly mean, that means the mean from Jan 15 - Feb 15, Feb 16 - March 15 and so on.
I tried using ds.shift like this:
ds = xarray.open_mfdataset('F:/PPT_Int*.nc',combine = 'by_coords', concat_dim="time")
AA = ds.shift(time = 15)
temp_m = AA.resample(time="1MS", skipna = False).mean()
But I'm unsure if it's a correct approach. I don't know if there's and option with resample that will do this.
