Introduction
post_it has been developped in IDL by Eric Guilyardi. It uses SAXO routines which has been developped by Sébastien Masson. post_it may help visualise and analyse netcdf data outputs from models automaticly without knowing properly the SAXO routines. However I recommend the user to have some notions of IDL to use this software. A good way to do this is also to read the SAXO documentation on http://forge.ipsl.jussieu.fr/saxo/
Directories and files
You should create two directories in your home directory :
'POST_IT' (where to download the sources through svn) 'SAXO' (which can be a link to Sébastien Masson's directory '/usr/home/smasson/SAXO_DIR/SRC/' if you have an account in LOCEAN or once again dowload the sources through svn).
post_it has a new structure since it has been managed by a svn server. The 'POST_IT' directory contains 7 main directories :
Launch IDL and POST_IT
File post_it.pro
General description and a first example
post_it.pro is the file in which you will work. It defines the in line commands which will be read by post_it so as to get the plot you want. For instance :
cmdline = [ $ ; var on exp grid plt timeave date1 spec disp proj out 'sohtc300 1 2L24 T xy 100y 1860 - 1 1 v', $ 'lastline 0' ]
This means that you want the sohtc300 variable to be visualised from a netcdf file called '2L24_100y_1860_*_grid_T.nc' on a 2D plot 'xy'.
The result is the following picture.
Heat content for 2L24 experiment
As a consequence, the names of the netcdf files are standardized and follow this pattern :
'Experiment'_'Frequency'_'Date1'_'Date2'_'Grid Type'.nc
