[netcdfgroup] Calculating medians, quartiles etc of a variable in a NetCDF file. [SEC=UNCLASSIFIED]

[Timothy Hume]

Hi,

I have an application where I would like to calculate quartiles of a variable in a NetCDF file (I am computing the trimean: TM = 0.25*(Q1 + 2Q2 + Q3) )

The NetCDF operators are excellent for computing arithmetic means, but don't include the capability to compute quartiles. Before I start writing my own code to compute quartiles, does anyone know of some software which already does this? Basically, I am looking for the equivalent of ncwa with a quartile operation.

Thanks,
