    Maps showing the mean incident light for the both the wet season and dry season in the Northern Marine Region. This data is the surface solar irradiance data obtained for NASA/GISS to allow the production of photosynthetically active solar irradiance fields to allow the calculation of primary production using satellite ocean colour products. The information comes from the Internation Satellite Cloud Climatology Project (ISCCP) using C1 data from multiple geostationary and polar orbiting meteorological satellites to provide a global view of the occurrence and properties of clouds. Atmospheric, cloud and surface data from ICSSP are used as input along with a scheme for computing clear-sky irradiance from the solar zenith angle, air properties, and surface reflectance. The scheme then uses simple cloud properties (cloud fraction, cloud optical thickness, and diffuse albedo) to produce total and photosynthetically active solar irradiance fields (Bishop and Rossow 1991; ISCCP Documentation of Cloud Data; Frouin et al. 1989). Input and output data fields are given in a 2.5° latitude and longitude grid. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

    Light time series were not used within this implementation of NWS-InVitro. In its place a simple equation was used to give average light levels derived from the output of the biogeochemical model of Herzfeld et al.(2006).

    The CSIRO Mk 3.0 climate system model contains a comprehensive representation of the four major components of the climate system (atmosphere, land surface, oceans and sea-ice). There are a simulations for a range of scenarios available for this model and also for the later CSIRO Mk 3.5 model. This simulation uses scenario PIcntrl which represents a Pre-industrial control experiment. This is a standard experiment for model intercomparisons. The scenario includes standard daily and monthly meteorological, and monthly oceanographic variables as netCDF files organised by variable and time period, totalling 4020 files. The data are accessible to authorised users via an OpenDAP server at CSIRO HPSC, and also from PCMDI in the U.S.A. It is also a contribution to the WCRP CMIP3 multi-model database and meets their formatting standards.

    ERA-40 2.5° by 2.5° reanalysis archive containing primary (4-times daily GRIB) and processed (4-times daily and climatological netCDF)data. The atmospheric model used for ERA-40 has the identifier IFS CY23r4 and is comprehensively documented on the ECMWF website at http://www.ecmwf.int/research/ifsdocs/CY23r4/index.html. It has 60 levels in the vertical, uses a T159 spherical-harmonic representation for the dynamical fields, and a reduced Gaussian grid with an approximately uniform 125 kilometre spacing for surface and other grid-point fields. An essential part of the ERA-40 activity was the production of an archive of data in GRIB format. Parameters such as the 4-times daily surface and pressure level files were processed to produce COARDS conforming netCDF files which are self describing, machine transperant and which employ a similar metacode specification to that in the NCEP re-analysis files. This makes it possible for users of the NCEP/NCAR reanalysis to be able to easily switch data input to ERA-40. Only the 4-times daily GRIB files have been further processed and are on a 2.5 by 2.5 degree horizontal grid (144 by 73 regular grid points) for each of the standard 23 pressure levels (0001, 0002, 0003, 0005, 0007, 0010, 0020, 0030, 0050, 0070, 0100, 0150, 0200, 0250, 0300, 0400, 0500, 0600, 0700, 0775, 0850, 0925 and 1000)

There are a simulations for a range of scenarios available for this model and also for the later CSIRO Mk 3.5 model. This simulation uses scenario Commit, which represents a commited climate change scenario with constant year 2000 GHG(Green House Gas) concentrations. This is a standard experiment for model intercomparisons. The scenario includes standard daily and monthly meteorological, and monthly oceanographic variables as netCDF files organised by variable and time period, totalling 900 files. The data are accessible to authorised users via an OpenDAP server at CSIRO HPSC, and also from PCMDI in the U.S.A. It is also a contribution to the WCRP CMIP3 multi-model database and meets their formatting standards.
