Posted by Lila Warszawski on July 4, 2012

With this email we we would like to convey to you a number of important updates on the following subjects:

1. Additional hardware at DKRZ
2. New ISI-MIP data blog
3. New abstracts on DKRZ server
4. Output file preparation: netCDF4 instructions
5. New ISI-MIP datasets available
6. Deadlines for simulation results
7. Latest changes to the simulation protocol

Please make sure to read through all of these important updates in more detail below:

1. Additional hardware at DKRZ

DKRZ will install additional hardware, most likely by the end of next week, which should speed up upload/download to/from the server. We apologize for the inconvenience caused by the recent slow transfer rates.

2. New ISI-MIP data blog


We have set up a blog for discussing input/output data issues. To access the blog, go to https://isimip.wordpress.com/; you will also find a link to the blog under http://www.isimip.org -> Input data. To create a post you need to be an author of the ISI-MIP data blog. Please register as a wordpress user under the given link, instructions can be found on the start page of the ISI-MIP data blog.
Comments on previous posts can be made without registration. We encourage you to use the blog for reporting and discussing data issues that are of potential interest to other participants. While we will continue to investigate any reported issues related to the input data, we believe that the blog will be a useful forum for direct discussions among ISI-MIP participants, and as such may also help to resolve problems faster in the future.

3. New abstracts on DKRZ server

Also, new abstracts continue to be sent to us, and are now available on the DKRZ server in zipped format (http://vre1.dkrz.de:8080/thredds/catalog/isi_mipEnhanced/abstracts/catalog.html). Please note that previously some abstracts were missing by accident. Now all currently existing abstracts can be found on the server.

4. Output file preparation: netCDF4 instructions

Please note that all output files should be in netCDF 4 format with a compression level of at least 5. This ensures adequate compression without having to zip and unzip files. In the attachment (as well as on our website http://www.isimip.org -> Output data -> Output file preparation) you find some instructions on how to convert files and use respective cdo tools. If you have uploaded files in netCDF3 already to Hamburg, there is however no need to replace them.

5. New ISI-MIP datasets available

Furthermore, we would like to let you know that the GFDL-ESM2M data (GCM3) is completely uploaded to the DKRZ server; the MIROC-ESM-CHEM data (GCM4) is being transferred at the moment and should be uploaded soon. (global.mean, monthly.mean, spinup und historical are already uploaded, the RCPs are currently being transferred.) Please find again attached the table with the version information for the variables, including information on how to distinguish the two HadGEM versions when you upload your data.

6. Deadlines for simulation results

Please note that the deadline for HadGEM results for all scenarios is August 15th. Deadline for RCP2.6 and 8.5 scenarios for GFDL and MIROC is August 30th. This enables us to have an almost complete minimal setting for analysis at the September workshop.

7. Latest changes to the simulation protocol

The simulation protocol has been updated and can be downloaded as pdf (http://www.isimip.org/ -> Simulation protocol). There, you will also find the corresponding addendum, which highlights all the recent changes at a glance. We strongly recommend you read the addendum as some of the changes may affect the way you carry out or report your simulations. In particular, recent changes have been made in the following sections:

- 4.1 Climate data
- 4.1.2 Spin-up data
- 5.2.2 Scenario naming conventions and explanations
- 5.2.3 Format for gridded data
- 5.2.5 Time intervals
- 6.3.1: Gridded biophysical model

As always, please do not hesitate to get in touch with us in case you have questions or comments!
