资源简介:
These data represent 6 hourly and 12 hourly instantaneous values of selected variables for ENSEMBLES (http://www.ensembles-eu.org). The list of output variables can be found in: http://ensembles.wdc-climate.de/output-variables. The model output was prepared for the IPCC Fourth Assessment 720 ppm stabilization experiment (SRES A1B).
The A1B scenario is the part of the A1 family which describes a balance across all energy sources. The experiment has been initialized in year 2000 of the 20C_1 run and continues until year 2100 with anthropogenic forcings included: CO2,CH4,N2O,O3,CFC11(including other CFCs and HFCs),CFC12; sulfate(Boucher) according to A1B. The experiment is extended until year 2230 with all concentrations fixed at their levels of year 2100 (stabilization experiment).
These datasets are available in netCDF format.
The dataset names are composed of
- centre/model acronym (e.g. IPCM4: Institut Pierre Simon Laplace)
- scenario acronym (e.g. SRA2: SRES A2)
- run number (e.g. 1: run 1)
- time interval (MM:monthly mean, DM:daily mean, DC:diurnal cycle, 6H:6 hourly, 12h:12hourly)
- variable acronym [with level value] (e.g. hur850: relative humidity, 850 hPa)
--> example: IPCM4_SRA2_1_MM_hur850
For this experiment 1 ensemble run was carried out.
Technical data to this experiment:
IPSL-CM4 (2003): atmosphere: LMDZ (IPSL-CM4_IPCC, 96x72x19); ocean: OPA8.2 (ipsl_cm4_v1_8, 2x2L31); sea ice LIM (ipsl_cm4_v1_8); land ORCHIDEE (orchidee_1_3)
本数据集包含了针对ENSEMBLES项目(http://www.ensembles-eu.org)所选变量的每6小时和每12小时瞬时值。输出变量的列表可查阅:http://ensembles.wdc-climate.de/output-variables。模型输出数据是为应对IPCC第四次评估报告中的720 ppm稳定化实验(SRES A1B)而准备。A1B情景是A1系列情景中描述跨所有能源来源平衡的部分。实验自20C_1运行中的2000年起始,直至2100年,包含人为强迫因素:CO2、CH4、N2O、O3、CFC11(包括其他CFCs和HFCs)、CFC12;以及根据A1B情景的硫酸盐(Boucher)。实验进一步扩展至2230年,所有浓度均固定在2100年的水平(稳定化实验)。这些数据集以netCDF格式提供。数据集名称由以下部分组成:
- 中心/模型缩写(例如:IPCM4:Institut Pierre Simon Laplace)
- 情景缩写(例如:SRA2:SRES A2)
- 运行编号(例如:1:运行1)
- 时间间隔(MM:月平均值,DM:日平均值,DC:日变化,6H:6小时,12h:12小时)
- 变量缩写[含层级值](例如:hur850:相对湿度,850 hPa)
---> 示例:IPCM4_SRA2_1_MM_hur850
对于此次实验,执行了一次集合运行。
实验的技术数据如下:IPSL-CM4(2003):大气:LMDZ(IPSL-CM4_IPCC,96x72x19);海洋:OPA8.2(ipsl_cm4_v1_8,2x2L31);海冰:LIM(ipsl_cm4_v1_8);陆地:ORCHIDEE(orchidee_1_3)
