一个新的全球三维(纬度,压力,时间)纬向平均月平均臭氧数据库,从1979年至2100年,已经创建。该数据库覆盖范围为87.5°S至87.5°N,纬度分辨率为5°,气压范围为878 hPa至0.0460 hPa,70个气压水平,相距约1km。整个周期分为两个子周期,即:(1)从1979年至2006年的观测,从几个来源的高垂直分辨率臭氧廓线测量,(2)从2007年至2100年的扩展基于化学气候模式(CCM)的预测。在每个纬度和气压水平上,CCM臭氧时间序列都进行了偏移和缩放,以更好地匹配1997年至2006年的测量结果,以确保从观测到模型输出的平稳过渡。预计这一新的数据库将提供适用于长期全球气候模型模拟的臭氧边界条件。
A new global three-dimensional (latitude, pressure, time) zonal mean monthly mean ozone database, from 1979 to 2100, has been created. The database extends from 87.5°S to 87.5°N at a 5° latitude resolution and from 878 hPa to 0.0460 hPa in 70 pressure levels ∼1 km apart. The full period is divided into two sub-periods, viz: (1) observations from 1979 to 2006 obtained from several sources of high vertical resolution ozone profile measurements, and (2) extensions from 2007 to 2100 based on chemistry climate model (CCM) projections. At each latitude and pressure level the CCM ozone time series are shifted and scaled to better match the measurements from 1997 to 2006 to ensure a smooth transition from observations to model output. This new database is expected to provide ozone boundary conditions suitable for long-term global climate model simulations.
