中亚区域CMIP6干旱情景数据(1900-2100)
收藏资源简介:
1)本数据是依据最新的22个CMIP6耦合全球气候模式模拟结果计算的Aridity Index(干燥指数)数据;2)计算公式为P/PET(降水与潜在蒸散发的比值),PET的计算依据PM公式;3)包括SSP2-4.5与SSP5-8.5两种情境的中亚大湖区1900年1月到2100年12月的月数据,分辨率为1度*1度;4)该数据可用于分析未来中等以及高排放情境下中亚大湖区干湿格局分布以及演变过程的预估。该数据已进行3个月滑动处理。
This dataset consists of Aridity Index data calculated using the simulation outputs of the latest 22 CMIP6 coupled global climate models. The calculation formula is P/PET, i.e., the ratio of precipitation to potential evapotranspiration, where PET is computed via the Penman-Monteith (PM) formula. It includes monthly datasets from January 1900 to December 2100 for the Great Lakes region of Central Asia under two scenarios: SSP2-4.5 and SSP5-8.5, with a spatial resolution of 1° × 1°. This dataset can be utilized to project and analyze the distribution and evolutionary processes of dry-wet patterns in the Great Lakes region of Central Asia under future moderate and high-emission scenarios. Additionally, this dataset has been processed with a 3-month moving average.
