Mean Standard Deviation

Domain-independent source code for forming the mean or mean-squared or standard deviation of a sequence of archive files.

HYCOM-tools/meanstd/src/

All programs read regional.grid.b at run-time to get idm and jdm for the particular region being processed.

The Makefile is configured to key on ../../config/$(ARCH)_setup for machine-dependent definitions, see the Config Setup wiki page. When running on (say) a Linux PC, ARCH is "intel*" and an individual make command for gfortran might be:
make hycom_mean ARCH=intelGF >& Make_hycom_mean.log

Typically all executables are created just once by editing Make_all.src for the correct ARCH and then issuing the command csh Make_all.csh.

The program hycom_mean will form the mean or mean-squared of a sequence of archive files. It can be used incrementally, i.e. a previously calculated mean or mean-squared can be part of the input.

The program hycom_std will form the standard deviation of a sequence of archive files, from their mean and mean-squared files.

The layered means are weighted by the layer thickness, but the mixed layer means and all non-layered means are simple means.
