Retreat around Model Outputs

The ORCHIDEE retreat took place in Jussieu (Darcy room) from 19th (whole day) to 20th (morning) of November.

Objectives : Put everyone in a collective effort to facilitate the use of ORCHIDEE for the users. Clean, standardize and correct all output variables of the model and prepare the xml file to be used with XIOS (replacement of IOIPSL for the output). Also discuss scientifically the current trunk simulation and model evaluation.

Detailed objectives and Guidelines

• Initial objectives described here: detailed objectives

• More information on XIOS are found under: ​https://forge.ipsl.jussieu.fr/orchidee/attachment/wiki/GroupActivities/Meetings/Developer/xios_in_orchidee_31mars2015_Ghattas_update4nov2015.pdf

• The main objective was to create a table for all outputs containing suggested changes to meet the GUIDELINES provided below Array of Outputs (field id, variable name, unit, ...)

• Guidelines to follow in order to standardize the ouputs XIOS Guidelines

• Working groups to prepare the work for the retreat Working Groups
