GFDL-CM3 Regional-Aerosol Simulations

Precipitation data from historical experiments (1860-2005) with the coupled model GFDL-CM3. Original data resolution 1x2.5, regridded here to 2.5x2.5. CMIP5 standard single-forcing experiments with anthropogenic aerosols (AA), greenhouse gases (GHG), and natural forcings (volcanic and solar; NAT) (3 members each); all-forcing experiment (ALL, 5 members), and 4 regional-aerosol experiments (3 members each), forced with different combinations of time-evolving anthropogenic aerosol emissions (i.e., all other forcings are kept at pre-industrial levels). Three of the ensembles have global time-varying historical emissions with the exception of those from (1) North America and Europe (PIAE, in the publication NoNAEU), (2) South Asia (PISA, in the publication NoSA), or (3) China (PICH, in the publication NoCH) fixed at pre-industrial levels. The fourth experiment has historical aerosol emissions for South Asia only and pre-industrial aerosol emissions in the rest of the world (PIRW, in the publication SAonly).

本数据集包含耦合模式GFDL-CM3的1860-2005年历史试验降水数据。原始数据分辨率为1°×2.5°，本次已将其重网格化至2.5°×2.5°。

试验包含CMIP5标准单强迫试验：分别以人为气溶胶（anthropogenic aerosols, AA）、温室气体（greenhouse gases, GHG）以及自然强迫（火山与太阳辐射，natural forcings, NAT）为强迫因子，各包含3个集合成员；全强迫试验（ALL，含5个集合成员）；以及4个区域气溶胶强迫试验（各含3个集合成员）。上述区域气溶胶试验均采用随时间演变的人为气溶胶排放驱动，其余强迫因子均固定在工业前水平。

其中3个集合试验采用全球时变历史排放，仅分别将（1）北美与欧洲的人为气溶胶排放固定为工业前水平（对应文献NoNAEU，记为PIAE）、（2）南亚的人为气溶胶排放固定为工业前水平（对应文献NoSA，记为PISA）、（3）中国的人为气溶胶排放固定为工业前水平（对应文献NoCH，记为PICH）。第四个试验仅保留南亚的历史人为气溶胶排放，全球其余区域的人为气溶胶排放均固定为工业前水平（对应文献SAonly，记为PIRW）。
