= iconPlot - General purpose plot script for the ICON climate model

This package contains a plotscript for: 

  * contour and vector/streamline plots

  * overlay of both

  * vertical sections

  * representing the ICON grid

== Installation

Download and run icon_plot.ncl directly with ncl

   ncl icon_plot.ncl altLibDir='"."'

or use nclsh from the contrib directory for easyer command line options

   nclsh icon_plot.ncl -altLibDir=.

Note that a config file $HOME/.icon_plot.rc is read in if available. Any 

commandline options can be set here. This is especially usefull for setting the altLibDir.

== Requirements

NCL 6.0 and CDO 1.5.x are required

== Usage

=== Basic Usage:

  ncl   icon_plot.ncl 'iFile="path/file.nc"' 'varName="ELEV"' 'oFile="test"' timeStep=1  levIndex=1

  nclsh icon_plot.ncl -iFile=path/file.nc    -varName=ELEV    -oFile=test   -timeStep=1 -levIndex=1

=== Select an special area of the globe with mapLLC (LowerLeftCorner) and mapURC (UpperRightCorner)   

  ncl   icon_plot.ncl 'iFile="path/file.nc"' 'varName="W"' 'mapLLC=(/35.0, -8/)' 'mapURC=(/55, 8/)'

  nclsh icon_plot.ncl -iFile=path/file.nc    -varName=W    -mapLLC=35.0,-8       -mapURC=55,8

=== Masking:

  ncl icon_plot.ncl 'iFile="oce_aqua_planet_O.R2B04L4_0001.nc"' 'varName="ELEV"' 'maskName="wet_c"' 

  ncl icon_plot.ncl 'iFile="oce.nc"' 'varName="W"' 'maskName="topo"' 'maskFile="icon_mask.nc"' 

=== Vectorplot:

  ncl icon_plot.ncl 'iFile="oce.nc"' 'vecVars="u-veloc v-veloc"' 'oFile="test"'

=== Vertical cross section:

  ncl icon_plot.ncl 'iFile="iconOutput.nc"' 'secLC=(/ 0.0,-90.0 /)' 'secRC=(/ 0.0,90.0/)' 'oType="png"' 'rStrg=""' 'tStrg="ICON coupled aqual planet"'

=== Overlay plot (vectors over contour plot)

  ncl   icon_plot.ncl  'iFile="iconOutput.nc"' 'varName="T"' 'vecVars="u-veloc v-veloc"'

  nclsh icon_plot.ncl  -iFile=iconOutput.nc    -varName=T    -vecVars=u-veloc,v-veloc

same for current atmo input

  ncl icon_plot.ncl  'iFile="atm.nc"' 'varName="T"' 'vecVars="U V"'

=== Atmosphere input plotted on the 3rd height level

  ncl icon_plot.ncl  'iFile="atm.nc"' 'varName="T"' 'atmLev="h"' levIndex=2

same but on pressure level

  ncl icon_plot.ncl  'iFile="atm.nc"' 'varName="T"' 'atmLev="p"' levIndex=2

Options can be combined execept showGrid=True (with nclsh: -showGrid) with vector and overlay plots

== Recommendations

Use the provided ncl wrapper script nclsh:

  ncl icon_plot.ncl 'iFile="iconOutput.nc"' 'secLC=(/ 0.0,-90.0 /)' 'secRC=(/ 0.0,90.0/)' 'oType="png"' 'varName="T"' vecVars='"u v"'

becomes

  nclsh icon_plot.ncl -iFile=iconOutput.nc -secLC=0.0,-90.0 -secRC=0.0,90.0 -oType=png -varName=T -vecVars=u,v

This is useful for write script which call other NCL application.
