IPCC DDC AR4 MRI-CGCM2.3.2 20C3M run1

These data represent monthly averaged values of selected variables for the Data Distribution Centre (DDC) of the Intergovernmental Panel on Climate Change (IPCC). (see also https://www.ipcc-data.org/)

The model output prepared for IPCC Fourth Assessment climate of the 20th Century experiment (20C3M).

These datasets are available in netCDF and GRIB format.

The initial condition is taken from the state of the pre-industrial control (PIcntrl) run at 1 years. The forcing of the experiment includes greenhouse gases (CO2, CH4, N2O and CFCs), sulfate aerosol direct effects, volcanoes and solar forcing.

For this experiment there are 5 ensemble runs available.

Model output data for CMIP3 in higher temporal resolutions and further variables are available in ESGF at https://esgf-node.llnl.gov/search/cmip3/.

本数据集反映了联合国政府间气候变化专门委员会（IPCC）数据分布中心（DDC）所选变量的月度平均值。（参见亦 https://www.ipcc-data.org/）该模型输出为IPCC第四次评估报告20世纪气候实验（20C3M）所准备。这些数据集以netCDF和GRIB格式提供。实验的初始条件取自工业化前控制（PIcntrl）的1年状态。实验的强迫因素包括温室气体（CO2、CH4、N2O和CFCs）、硫酸盐气溶胶的直接效应、火山活动和太阳辐射强迫。对于本实验，共有5次集合运行可用。在ESGF（https://esgf-node.llnl.gov/search/cmip3/）中可获取CMIP3模型输出数据，其具有更高时间分辨率和更多变量。}
