# Those functions would never have seen the day without Hui Du, #
# usually referred to as Super-Hui. #
# #
# He made a crucial work to develop what ended up below in the functions #
# that computes the sea ice extent, sea ice area, ocean heat content and #
# meridional overturning streamfunction. #
# Especially, he developped new options from the cdftools sources to be #
# able to compute the heat content in different basins. #
# #
#@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
# You want to make available a new diagnostic ? @
# @
# 1) Get an MMO tar files from any experiment on cfunas @
# 2) Write a bash function that works on a grid_T or grid_U or grid_V or @
# grid_W file or a combination from this MMO file @
# --> You can test your function by defining the CON_FILES and NEMOVERSION @
# variables and by sourcing the current file, the meshmasks will be @
# available after sourcing, remember to source again after any @
# modification of your function @
# --> Your function should work on input files of any resolution @
# ORCA1/ORCA025/ORCA2 @
# --> Your function should work on input files of any time length @
# --> The output file should contain a proper time axis that you can copy @
# from your input file @
# --> The output file should be at most a 3d field including the time @
# dimension @
# 3) Write a short description of your function, and add its name to the @
# list above @
# 4) Go the the ocean_pp.sh script to add a call to your function @
# @
# Any doubt ---> vguemas@ic3.cat @
