hi, users
thanks the people who help me.
a low-pass filter is imposed on annual global_mean time series temperature change data ,which removes fluctuations with periods less than 10 years(11-point smooth).
i use the function wgt = filwgts_lancos (9, 0, 0.2, -999., 1) to get the wgts, and use ts = wgt_runave(ts(time|:), wgt, 0) to get the smooth data.
but how to know the data is 11-point smooth?
yours sherry
