Job_Post_FLUXNET Visualisation tool

It generates time-series of different fluxes :

• NEE, GPP, TER
• Latent Heat, Sensible Heat

For different datasets :

• The simulation that you have launched
• The in-situ observations
• A simulation of "reference" (eg. a former simulation)

For different time frequency

• Daily cycle
• Seasonal cycle
• Interannual variability

It also creates Taylor diagrams for evaluating the performances of the model for the different sites, variables and time frequencies. Within these Taylor diagrams, the tail of the arrow indicates the performance of the reference version and the head of the arrow indicates the performance of the evaluated version.

Where is Job_Post_FLUXNET located ?

Job_Post_FLUXNET is under modipsl/config/ORCHIDEE_OL/FLUXNET dir. Installation is similar to Job_FLUXNET_Validation.

How to modify the fluxnet.card ?

• The observation file is the type of file in which Fluxnet data are stored.
• The reference file is the output file of ORCHIDEE (sechiba component) of a former simulation used as reference.
• Here below is an example how observation and reference file can be set:

  observation_file_path='/home/orchidee01/vuichard/Input_Fluxnet/${Site}.nc'
  reference_file_path='/home/orchidee01/vuichard/ORCHIDEE_1951/IGCM_OUT/OL2/Fluxnet_Tao/${Site}_sechiba_hist.nc'
  

How to use it ?

my_prompt>> ksh
my_prompt>> nohup ./Job_Post_FLUXNET fluxnet > out_Post 2>&1 &

Requirement

On Obelix, you need to have a passphrase for connecting to obelix when launching automatically new jobs via ssh.
From your home root directory: If the '.ssh' directory doesn't exist, create it.
Then, go in this directory

my_prompt>> cd .ssh

Then, type:

my_prompt>> ssh-keygen -t rsa -N ""

Then,

my_prompt>> cp id_rsa.pub authorized_keys

or, if the file "authorized_keys" already exists:

my_prompt>> cat id_rsa.pub >> authorized_keys

Some example of charts created by Job_Post_Fluxnet

• Example 1 : Sensible Heat (seasonal variations)

• Example 2 : GPP (daily cycle)

• Example 3 : Total Ecosysyem Respiration (Inter-annual variations

• Example 4 : Taylor diagram for evaluating GPP hour-to-hour variation for the Grassland sites (GRA)
