全球未来情景下排放网格数据库

本数据库对各国的未来排放设置了快速减排、中速减排以及慢速减排即低中高的排放情景，各情景的网格排放数据以RCP4.5情景的排放网格为基准，根据国家排放路径更改碳排放网格数据，对每个国家或团体，将其网格人口作为权重，加权分配其碳排放，获得全球不同情景下的排放网格数据，网格化的未来碳排放情景数据，时间分辨率为月尺度，空间分辨率为0.9度*1.25度，共计730MB。为气候模式模拟不同排放情景下未来的气候提供了数据支持。

This database establishes three future emission scenarios for nations: rapid emission reduction, moderate emission reduction, and slow emission reduction, which correspond to low-, medium-, and high-emission scenarios respectively. The gridded emission data for each scenario is grounded in the emission grid of the RCP4.5 scenario, with the carbon emission grid data adjusted based on national emission trajectories. For each country or regional group, its gridded population is employed as a weight to conduct weighted allocation of its total carbon emissions, thereby producing global gridded emission data under different scenarios. The gridded future carbon emission scenario data features a monthly temporal resolution and a spatial resolution of 0.9° × 1.25°, with a total file size of 730 MB. It provides critical data support for climate models to simulate future climates under various emission scenarios.
