Availability of data, File format and SoftwareAccess to the UJCC data sets is available via the UJCC data browser directory . Alternatively you can ftp the data from ftp.ceda.ac.uk.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.More details of HadGEM1a can be found here (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 oceanThe BADC have provided a list of the simulations that make up the UJCC datset matrix in the BADC archive. A comprehensive overview of the matrix of UJCC climate models can be found here. UJCC statusThe current status of the UJCC dataset at the BADC can be foundhere. 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. Data file formatAll UJCC data are held as 64 bit UM pp files. SoftwareSoftware is available to manipulate and view the data. xconv provides an easy to use pointand click interface to the data.convshprovides a subset of the functionality of xconv, but in a scriptableform, so it can be used to automate some common data processing tasks.Jeff Cole at CGAM Reading, who developed both xconv and convsh,provides some example uses ofconvsh.
