CDO

This concerns the percentile calculation. CDO allows percentile starting from 1 to 99. How to obtain higher percentile estimates, starting from 99.1 to 99.9 percentiles?

As per the CDO documentation, the default number of histogram bins i 101. The default can be overridden by setting the environment variable CDO PCTL NBINS to a different value. So I think manipulating CDO_PCTL_NBINS (setting higher number of bins), will do the needful. Suggest me how to appropriately manipulate CDO_PCTL_NBINS, so as to obtain the higher percentile estimates (99.1 to 99.9) ?.

Thanks in advance.
