Requirements to use the C ESM EP

The C-ESM-EP works both on Ciclad and Curie. The C-ESM-EP uses a setenv_C-ESM-EP.sh script that sets your environment properly when running an atlas.

However, you might need to check some other things (see below) to be sure that you can run the C-ESM-EP.

Access to a web server

On Ciclad, you need to have a space on the web (often known/refered to as 'dods') server. If you encounter this error:

[jmlod@ciclad-ng C-ESM-EP]$ python run_C-ESM-EP.py standard_comparison/
Traceback (most recent call last):
File "run_C-ESM-EP.py", line 220, in 
os.makedirs(webspace)
File "/opt/anaconda/lib/python2.7/os.py", line 150, in makedirs
makedirs(head, mode)
File "/opt/anaconda/lib/python2.7/os.py", line 150, in makedirs
makedirs(head, mode)
File "/opt/anaconda/lib/python2.7/os.py", line 157, in makedirs
mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/prodigfs/ipslfs/dods/jmlod'

this means that you do not have a space on dods. Please contact the support of the IPSL mesocentre to ask for a space on dods (see the e-mail address meso-support in the prompt when you connect to ciclad).

On Curie you will automatically have access to the thredds.

source setenv_C-ESM-EP.sh

If you have this error when running set_available_period_ts_clim.py:

fabric@ciclad-ng:~/users/jmlod/C-ESM-EP> python set_available_period_ts_clim.py standard_comparison/
Traceback (most recent call last):
File "set_available_period_ts_clim.py", line 18, in 
from CM_atlas import *
ImportError: No module named CM_atlas

This means that you need to have CliMAF in your path. To fix this, simply do:

source setenv_C-ESM-EP.sh

And try again.

R libraries for TuningMetrics, ParallelCoordinates

You will need the 'optparse' library to run TuningMetrics and ParallelCoordinates. On your account, do:

Select a CRAN mirror (any); it will install the package.

This should get you going with R for TuningMetrics and ParallelCoordinates

Python libraries

Running the C-ESM-EP requires the following python libraries:

• cdat (cdms2)
• netcdf4
• numpy
• matplotlib
• windspharm (optional, for O. Torres diagnostics)
