NARCliM1.0 climate projections

__What is NARCliM?__\r\n\r\nThe New South Wales and Australian Regional Climate Modelling (NARCliM) project develops high-resolution regional climate projections that cover NSW and South-eastern Australia at a higher resolution and the Australasian continent and beyond at another resolution (named the NARCliM and CORDEX domains, respectively).\r\nComputer modelled climate projections are the best information we have available on our future climate. NARCliM has been designed to help government, industry and community in NSW and Australia plan for our future with robust regional and local scale data.\r\nThe NARCliM project uses currently available global climate models (GCM) and greenhouse gas (GHG) emissions scenarios from the latest Coupled Model Intercomparison Project (CMIP) used in the IPCC reports and applies regional dynamical downscaling using the latest Weather Research and Forecasting model (WRF). NARCliM generates critical climate indices for a broad range of applications and climate change adaptation and risk analysis.\r\n\r\n__NARCliM1.0__\r\n\r\nThe NARCliM project began as a multi-agency partnership led by the NSW Government, partnered with the ACT Government, and with contributions from the Climate Change Research Centre (CCRC) at the University of New South Wales.\r\nNARCliM1.0 was released in 2014. It contains simulations from four CMIP3 GCMs and three regional climate models (RCM) using WRF3.3 for one future GHG scenario (SRES A2). Time periods included are 1990 to 2009, 2020 to 2039 and 2060 to 2079, with a grid resolution of 10km for South-eastern Australia (NARCliM domain) nested within a 50km grid for Australasia (CORDEX domain). NARCliM1.0 data has been used for a range of NSW climate adaptation and impact studies and climate change visualisations.\r\n\r\nNARCliM1.0 features:\r\n* Historical period: 1990 to 2009\r\n* Future simulation periods: 2020 to 2039 and 2060 to 2079\r\n\r\nSome common variables projected by NARCliM1.0 include:\r\n* Temperature\r\n* Precipitation\r\n* Wind speed\r\n* Surface evaporation\r\n* Soil moisture\r\n* Bias corrected and post processed data\r\n* Three National Centres for Environmental Predictions (NCEP) reanalysis forced simulations were run from 1950 to 2009.\r\n\r\n__Model output__\r\n\r\nFor access to NARCliM climate projections data, please visit the NSW Climate Data Portal or the National Computational Infrastructure at ANU. The Climate Data Portal provides users access to NARCliM's most commonly used "core variables" at daily and monthly frequencies. Additional variables useful for specialist analysis are available upon request.

什么是NARCliM？

新南威尔士州与澳大利亚区域气候建模（New South Wales and Australian Regional Climate Modelling, 缩写NARCliM）项目旨在构建高分辨率区域气候预估数据：针对新南威尔士州与澳大利亚东南部区域采用更高分辨率，针对澳大拉西亚大陆及更广范围则采用另一套分辨率（分别对应NARCliM域与CORDEX域）。

基于计算机数值模拟的气候预估数据是当前我们获取未来气候信息的最优途径。NARCliM项目旨在助力新南威尔士州与全澳的政府、产业界及社会群体，依托可靠的区域与局地尺度数据开展未来规划。

本项目采用IPCC报告中所使用的最新耦合模式比较计划（Coupled Model Intercomparison Project, 缩写CMIP）的现有全球气候模式（Global Climate Model, 缩写GCM）与温室气体（Greenhouse Gas, 缩写GHG）排放情景，并依托最新的天气研究与预报模式（Weather Research and Forecasting, 缩写WRF）开展区域动力降尺度研究。NARCliM可生成适用于多元应用场景、气候变化适应与风险分析的关键气候指标。

NARCliM1.0版本

NARCliM项目最初由新南威尔士州政府牵头组建多机构合作联盟，合作伙伴包括澳大利亚首都领地政府，同时得到新南威尔士大学气候变化研究中心（Climate Change Research Centre, 缩写CCRC）的技术支撑。

NARCliM1.0于2014年正式发布。该版本包含4个CMIP3全球气候模式与3个区域气候模式（Regional Climate Model, 缩写RCM）的模拟结果，采用WRF3.3模式针对单一种类的未来温室气体排放情景（SRES A2）开展模拟。模拟时段涵盖1990-2009年、2020-2039年以及2060-2079年；其中澳大利亚东南部区域（NARCliM域）的网格分辨率为10km，该网格嵌套于覆盖澳大拉西亚区域的50km分辨率网格（CORDEX域）之上。

NARCliM1.0数据集已被广泛应用于新南威尔士州的多项气候变化适应与影响研究，以及气候变化可视化项目中。

NARCliM1.0的核心特征如下：
* 历史模拟时段：1990-2009年
* 未来预估时段：2020-2039年与2060-2079年

NARCliM1.0所预估的常见变量包括：
* 气温
* 降水量
* 风速
* 地表蒸发量
* 土壤湿度
* 经过偏差校正与后处理的数据
* 开展了3组以美国国家环境预报中心（National Centres for Environmental Predictions, 缩写NCEP）再分析数据为强迫场的模拟试验，模拟时段为1950-2009年。
