ACCMIP: NIWA (National Institute of Water and Atmospheric Research, New Zealand) climate model output
Abstract
The Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) was organized under the auspices of Atmospheric Chemistry and Climate (AC&C), a project of International Global Atmospheric Chemistry (IGAC) and Stratospheric Processes And their Role in Climate (SPARC) under International Geosphere Bisosphere Programme (IGBP) and World Climate Research Programme (WCRP). The Atmospheric Chemistry and Climate Model Intercomparison Project (ACC-MIP) consists of several sets of simulations that have were designed to facilitate useful evaluation and comparison of the AR5 (Intergovernmental Committee on Climate Change Assessment Report 5) transient climate model simulations.
This dataset contains measurements from climate simulations from NIWA of the 20th century and the future projections, which output feedback between dynamics, chemistry and radiation in every model time step. The data are collected from running the latest set of ozone precursor emissions scenarios, which output tropospheric ozone changes from 1850 to 2100.

| Title | UM-CAM Model deployed on NIWA (National Institute of Water and Atmospheric Research, New Zealand) Computers |
| Abstract | This computation involved: UM-CAM Model deployed on NIWA (National Institute of Water and Atmospheric Research, New Zealand) Computers. The UM-CAM model explores how changes in the levels and locations of ozone precursor emissions, (such as nitrogen oxides NO and NO2; referred to as NOx), carbon monoxide (CO) and volatile organic compounds (VOCs), including methane, could affect tropospheric ozone abundances, from the pre-industrial period to future projections. The UM-CAM model explores how changes in the levels and locations of ozone precursor emissions, (such as nitrogen oxides NO and NO; referred to as NO, carbon monoxide (CO) and volatile organic compounds (VOCs), including methane, could tropospheric ozone abundances, from the pre-industrial period to future projections. NIWA (National Institute of Water and Atmospheric Research, New Zealand) are using the atmospheric component of the Hadley Centre’s model to investigate causes of natural climate variability in the Southern Hemisphere. They are also using a regional climate model (RCM) to simulate climate change over New Zealand. Three dimensional models which simulate the atmosphere are called Atmospheric General Circulation Models (AGCMs), and have been developed from weather forecasting models. Similarly, Ocean General Circulation Models (OGCMs) have been developed to simulate the ocean. These models typically divide the atmosphere or ocean into a horizontal grid with a horizontal resolution of latitude and longitude, with 10 to 20 layers in the vertical. Both AGCMs and OGCMs have been used in "stand-alone" mode, but can also be used together as Atmosphere Ocean General Circulation models AOGCMs. NIWA (National Institute of Water and Atmospheric Research, New Zealand) are using the atmospheric component of the Hadley Centre;s model to investigate causes of natural climate variability in the Southern Hemisphere. Computer power is still a limitation for GCM (Global Climate Models) simulations extending over hundreds of years. As a consequence the resolution is fairly coarse (typically 176; latitude grid size in the IPCC 2007 models). One solution to this is to run a regional climate model (RCM), which represents a limited area of the globe at a much higher resolution (10 to 30 km). NIWA uses a RCM to simulate climate change over New Zealand. |
