Representative Concentration Pathways (RCP) are climate change scenarios to project future greenhouse gas concentrations. These pathways (or trajectories) describe future greenhouse gas concentrations (not emissions) and have been formally adopted by the IPCC.

代表性濃度路徑 （Representative Concentration Pathway，簡稱RCP）是IPCC採用的 溫室氣體 濃度（而非排放）軌跡。 IPCC於2014年發佈 第五次評估報告 （AR5）中所採用的四種路徑進行氣候建模及研究。 這些路徑用來描述不同的 氣候變化情景，這些情景都被認為有可能發生，取決於往後各年全球排放的 溫室氣體 數量。 RCP（最初設定有RCP2.6、RCP4.5、RCP6和RCP8.5四種路徑）以2100年當時可能的 輻射強迫 值程度（分別為2.6、4.5、6和8.5瓦/平方 …

The RCP database aims at documenting the emissions, concentrations, and land-cover change projections of the so-called "Representative Concentration Pathways" (RCPs). Information about the RCPs and the scenario development process for the IPCC AR5 can be found in the IPCC Expert Meeting Report on New Scenarios and Moss et al. (2010) .

This paper summarizes the development process and main characteristics of the Representative Concentration Pathways (RCPs), a set of four new pathways developed for the climate modeling community as a basis for long-term and near-term modeling experiments.

The RCP database, which documents the emissions, concentrations, and land-cover change projections based on these four RCPs, is intended to provide input to climate models. They will also facilitate and expedite future climate change assessments across the …

2011年8月5日 · The greenhouse gases covered in the RCP work include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O) and halocarbon emissions. The air pollutants include sulfur dioxide (SO 2), nitrogen oxides (NO x), volatile organic compounds (VOC), carbon monoxide (CO), organic carbon (OC), black carbon (BC), and ammonia (NH 3).

为了对未来气候作出评估，IPCC第五份评估报告采用了四个温室气体浓度情景，按低至高不同代表路径浓度 (RCP)排列分别为RCP2.6、RCP4.5、RCP6.0和RCP8.5，其中后面的数字表示到2100年辐射强迫水平2.6W m-2 到 8.5 W m-2。 基于这些温室气体浓度情景，各个气候中心及研究机构利用不同复杂程度的电脑模式来推算未来的全球气候。 气候推算并不是天气或季度预测。 气候推算的目的是在预设的温室气体浓度情景下，从长远角度来描述未来气候的可能变化，而不是预测 …

The greenhouse gas mixing ratios, in particular CO2, N2O, HFCs, PFCs, SF6 and the ozone depleting substances ODS, are recommended for being used in the 20th century runs in preparation of IPCC AR5. Here, data is provided for the full time span from 1765 to 2005, although modelling groups might decide to start their model runs only in 1850.

2011年8月9日 · We present the greenhouse gas concentrations for the Representative Concentration Pathways (RCPs) and their extensions beyond 2100, the Extended Concentration Pathways (ECPs). These projections include all major anthropogenic greenhouse gases and are a result of a multi-year effort to produce new scenarios for climate change research.
