UK-Japan Climate Collaboration (UJCC) Model Matrix data

Earth-system modelling data from the UK-Japan Climate Collaboration (UJCC). The project is a joint project between the Hadley Centre (DEFRA) and the NCAS-CGAM (Centre for Global Atmospheric Modelling) at the University of Reading. UJCC makes use of a broad group of models in order to systematically explore the role and value of resolution in climate system research. The dataset comprises of UJCC 30 year simulations from models at resolutions of either (1.25 lat x 1.875 lon) or (0.83 lat x 1.25 lon) with differing degrees of atmosphere-ocean coupling (1 degree ocean or 1/3 degree ocean). The dataset also includes NUGAM (Nihon-UK Global Environmental Model) Atmosphere only simulations and NUGEM Coupled atmosphere and ocean simulations which are both at the same resolution (0.83 lat x 0.56 lon, corresponding to ~60 km in mid-latitudes).

UJCC is making use of a broad group of models in order to systematically explore the role and

value of resolution in climate system research. All the UJCC models have as their baseline

science the initial reference HadGEM1a models used at the Hadley Centre. These build on the IPCC

AR4 version of the model, and include various small improvements to the science and fixing of

known problems.

(this link is restricted to those with HiGEM privileges).

The UJCC data archived at the BADC are 30 year simulations from models at the following resolutions:

N96 Atmosphere (1.25 lat x 1.875 lon), 1 degree ocean (HadGEM1a)

N96 Atmosphere (1.25 lat x 1.875 lon), 1/3 degree ocean

N144 Atmosphere (0.83 lat x 1.25 lon), 1 degree ocean

N144 Atmosphere (0.83 lat x 1.25 lon), 1/3 degree ocean (HiGEM)

Simulations from the Nihon-UK Global Environmental Model (NUGEM) will also be archived at the BADC.

NUGEM is a version of HadGEM1a run at very high N216 resolution (0.83 lat x 0.56 lon, corresponding

to ~60 km in mid-latitudes). The BADC will be archiving:

NUGAM Atmosphere only version of NUGEM

NUGEM Coupled atmosphere and ocean

The BADC have provided a list of the simulations that make up the UJCC datset matrix in the BADC archive.

UJCC status

The current status of the UJCC dataset at the BADC can be found

here.

We have now launched a web page showing the

status of the current UJCC-HiGEM simulation.

This service displays the evolution of certain key parameters including net top of atmosphere

radiation flux, global mean sea surface and surface temperature and ocean salinity.

The North Atlantic Oscillation and Nino-3 indices are also shown.

These plots are updated as new data from the UJCC-HiGEM simulation arrives at the BADC.

Software

Software is available to manipulate and view the data.

xconv provides an easy to use point

convsh

provides a subset of the functionality of xconv, but in a scriptable

form, so it can be used to automate some common data processing tasks.

provides some example uses of

convsh.
