Atmospheric River Tracking Method Intercomparison Project Tier 1 Source Data and Catalogues
收藏资源简介:
Atmospheric River Tracking Method Intercomparison Project (ARTMIP) Tier 1 developer catalogues and source data. Each ARTMIP method/algorithm (named by developer) submits a catalogue comprised of 0's (no AR exists) or 1's (yes AR exists) for each time slice, for each grid point, using MERRA-2 reanalysis data from January 1980 through June 2017. Derived quantities required for algorithms, such as IVT or IWV, were computed by the ARTMIP project so that all methods use the exact same data.Errata: Reid ARDTs have a discontinuity bug at the wrapping point between negative 180 and 180 degrees.
大气河流追踪方法比对计划(Atmospheric River Tracking Method Intercomparison Project, ARTMIP)一级开发者目录与源数据集。 各由开发者命名的ARTMIP方法或算法,需基于1980年1月至2017年6月的MERRA-2再分析数据,针对每个时间切片与每个网格点,提交一份由0(无大气河流)与1(存在大气河流)构成的目录文件。算法所需的衍生物理量,如整层水汽通量IVT(Integrated Vapor Transport)、整层水汽含量IWV(Integrated Water Vapor),均由ARTMIP计划统一计算,确保所有方法使用完全一致的源数据。 勘误:Reid团队开发的大气河流检测工具ARDTs(Atmospheric River Detection Tools)在-180度与180度经度的绕转边界处存在不连续缺陷。
