Downloading from Met Office Archives (MASS/MOOSE)

  • We are now able to download model outputs from the UK Met Office MASS archive system on request - Downloading from MASS



  • NOAA is changing the delivery mode of OISST and also switching to netcdf4 format. I'm currently reviewing our download procedure and we'll finally have a new raw and modified version for this data. To help to transition the v2-0_modifed version will stay in place.

WRF v3.9

  • The compiling scripts for WRF and WPS have been revamped. They now accept command-line arguments for customisation rather than requiring users to hack into the script. See details on the installation page for v3.9. If you would like more command-line options that's easy to add so please tell CMS about it.

River runoff regridding tools


  • Repeat Year Forcing (RYF) derivative datasets of the Japanese Reanalysis for Ocean Model forcing (JRA55-do) are available under the same directory as JRA55-do. In addition there are regridded runoff data for different MOM ocean configurations available in ua8. Contact for more information.

ERA-Interim for WRF

  • Bug information: The information on how to use the ERA-Interim dataset in WPS on the wiki (here) and the automatic script wps-era referenced on that page were erroneous. This code and instructions would potentially create erroneous fields along the coast lines. These instructions and script have now been updated. Please update your code and regenerate your WRF input files if you have used wps-era


  • Bug information: some files in the TRMM dataset at NCI got corrupted. The dataset has now been repaired and more stringent tests have been added to help avoid corrupted files in the future.


  • A version of ACCESS1.0 coupled to KPP using OASIS3-MCT was finalised. UMUI jobs vatae (N96 resolution) and vaski (N48) can be used as a basis. Further documentation in ACCESS-MOSES-KPP.


CMIP induction and ARCCSSive training

  • We added to the NCI online training website a CMIP induction which includes training on how to use the ARCCSSive python module. To access the course use your NCI account to login here


  • JRA-55 based surface dataset for driving ocean-sea ice models, JRA55-do v 0.8 and v1.1 are now available in /g/data1/ua8/JRA55-do/v0-8 (v1-1). This dataset is covered by a license and it's not officially published yet, so you shouldn't re-distribute it. Please, follow Terms of Use available in the main directory.

WRF v3.9

  • The latest version of WRF (v3.9) is now available on Raijin. Please find detailed instructions here

Conda Updates


    • wrf-python A collection of diagnostic and interpolation routines for use with output from the Weather Research and Forecasting (WRF-ARW) Model.
    • pyferret PyFerret is a Python module wrapping Ferret. The pyferret module provides Python functions so Python users can easily take advantage of the Ferret's abilities to retrieve, manipulate, visualize, and save data. (Python 2.7 only)
    • SymPy SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python.


Data collections Updates

  • Expansion of MERRA-2 collection at NCI with the inst3d_3d_asm_Np data. View MERRA-2 page

Conda Updates

  • Several packages have been added to the public Anaconda environments

    • metpy: MetPy is a collection of tools in Python for reading, visualizing and performing calculations with weather data.
    • windspharm: windspharm is a Python package for performing computations on global wind fields in spherical geometry.
    • python-cdo: Python bindings for CDO
    • pyart: The Python ARM Radar Toolkit
    • bokeh: Bokeh is a Python interactive visualization library that targets modern web browsers for presentation.


Python libraries at NCI

  • We've moved the Python libraries installed with Miniconda to a public space (/g/data3/hh5/public/modules) so there is no need anymore to be part of ACCESS to use it. See the updated instructions

Massdata utility

  • Are you moving data to/from massdata? Are you having issues with the copy stopping in the middle of things and impossibility to restart from where it failed? Aidan wrote a small utility to help with that. It’s available to anyone, info:



  • The latest release of MPAS-Atmosphere has been installed on Raijin. This model will probably supplant WRF sometime in the future.

Python libraries at NCI

  • We've installed some Python libraries using Miniconda in /g/data1/access. The aim is to facilitate access to and management of commonly used Python libraries on Raijin, Accessdev and VDI. It also enables users to locally install their own libraries using Miniconda without duplicating the centrally installed libraries. For the moment, users have to be part of the ACCESS group on Raijin to use these (if you are not, just ask access on but we plan to make it public access. More details are here.

Sharing facility at NCI

  • We worked at NCI to enable users to share data stored on Raijn with collaborators who don't have access to NCI. This is aimed for work in progress which can not be published and opened publicly. The files are accessible for a short time only to allow your collaborators to download them to their own storage. We are working on making it user-friendly but if you need to share some data in the meantime, please ask

Updating OpenMPI library for MOM

  • After the new quarter maintenance, some MOM jobs experienced some stalling behaviour at the end of the job. This mainly affect large configurations (0.1°). The fix is to recompile MOM using the openmpi/10.2.1 version. If you don't know whether you should worry about it or how to recompile, please contact


  • The latest manual is now on the CMS wiki. Just follow the NU-WRF link in the navigation sidebar.




  • The Accesscollab UMUI server is no longer supported, and we can't guarantee the safety of data on it. Please move any data on the 'Collab' page of the UMUI to the 'Accessdev' or 'Collab(local)' page. The 'Collab (local)' page contains copies of the Accescollab database from last year, if your jobs are present there no further action is required.
    To move an experiment folder right click on it and select 'copy' then go to the 'accessedev' or 'collab(local)' page and use the 'paste' button in the top right of umuix to copy all jobs in that folder.
  • NIWA's um2netcdf.x conversion script is now available as ACCESS module um2netcdf-niwa too
