DYAMOND Summer
========================================



**Simulation Period:** 
   1 August 2016  - 10 September 2016, 

   with 10 day spin-up peripode and 30 days analysis periode

**Field Experiment:** 
   NAR-VAL2 tropical field study

**Experiment:** 
   Global atmosphere models with a storm resolving grid spacing of 5 km or less. 
   Detailed information can be found at the `DYAMOND Summer protocol(pdf) <https://www.esiwace.eu/services/dyamond-initiative/dyamond-specific-pages-and-material/dyamond-protocol>`__\ . 

   Initital data are provided at the `ESiWACE webpage <https://www.esiwace.eu/services/dyamond-initiative/services-dyamond-summer>`__\.



Completion of the simulation had been done until May 2018.

Getting the data
--------------------------

Since the DYAMOND data sets form hundreds of terabytes of data, only parts are available on disk. 
**To access further DYAMOND Summer data files,** you will need to make a request within the DYAMOND data library. 
The ESiWACE team at DKRZ will download the data for you to Levante, thereby making it accessible to all DYAMOND users. 
A detailed description how to search for and request archived data files is given at :ref:`DYAMOND-library` and the README file at :file:`/fastdata/ka1081/DYAMOND/README`.
Unused data files will be deleted on a regular basis.



.. _DYAMOND-summer-processing-data:

Working with the data
---------------------

You are most invited to use our systems for analyzing the data (instead of copying them around). 
Our post-processing project 1153 has some compute resources that can be used for analysis scripts. 
Therefore, we recommend to store project data under ``/work/bb1153/<user-id>/`` and use the temporary storage in your scratch folder ``/scratch/*/<user-id>`` for processing of large data sets. 
For more information about the Levantes file systhem its quotas and backups, see `The file systems of Levante (docs.dkrz.de) <https://docs.dkrz.de/doc/levante/file-systems.html>`__.  

For model and run descriptions see :ref:`Participating models and description <DYAMOND-summer_participating_models_and_description>` above.


Direct file access
++++++++++++++++++

DYAMOND Summer data sets can be found in the :ref:`DYAMOND-library` at :file:`/fastdata/ka1081/DYAMOND/data/summer_data/` stored at the DKRZ’s Levante supercomputer.
The **data sets are read-only**, so you will have to define the respective subfolder as the source directory for your post-processing scripts. 


DKRZ provides a JupytherHub server to analyse the big data sets stored at DKRZ by using Python, R or Julia scripts running directly on Levante. 
For further information visit our page :ref:`dkrzs_jupyterhub`.
