Notes on reproducing the figure from the provided data

---------------------------------------------------

Multimodel ensemble means and percentiles are calculated after weighting individual members with the inverse of the ensemble size of the same model. The weight is provided as the weight attribute of ens_cmip5 and ens_cmip6.

If X(i) is the array, and w(i) the corresponding weight.

- Mean shoud be sum_i(X(i) * w(i)) / sum_i(w(i))

- For percentile values,

1. Sort X and w so that X is in the ascending order

2. Accumulate w until i = j so that accumulated(w)/sum_i(w(i)) equals or exceeds the specified percentile level (e.g. 0.05)

3. Use X(j) or (X(j) + X(j - 1))/2 as the percentile value
