Reanalysis Tropopause Data Repository

This data repository provides access to tropopause parameters estimated from meteorological reanalyses. The tropopause data sets provided on this web site have been created using meteorological reanalyses distributed by the European Centre for Medium-Range Weather Forecasts (ECMWF), the National Aeronautics and Space Administration (NASA), the National Center for Atmospheric Research (NCAR), and the National Centers for Atmospheric Prediction (NCEP). Currently, the repository covers ERA-Interim, MERRA-2, and the NCEP/NCAR Reanalysis 1 for the time period from 2000 to 2018 and ERA5 from 2009 to 2018. The tropopause data files provide geopotential height, pressure, temperature, and water vapor volume mixing ratio for the WMO 1st and 2nd tropopause, the cold point, and the dynamical tropopause.

本数据仓库提供对来自气象再分析估计的平流层参数的访问。本网站提供的平流层数据集系采用欧洲中期天气预报中心（ECMWF）、美国国家航空航天局（NASA）、美国国家大气研究中心（NCAR）和美国国家大气预测中心（NCEP）分发的气象再分析数据创建而成。目前，该仓库涵盖了从2000年至2018年的ERA-Interim、MERRA-2以及NCEP/NCAR再分析1，以及从2009年至2018年的ERA5。平流层数据文件提供了WMO第1和第2平流层、冷点以及动力平流层的位温高度、气压、温度和水汽体积混合比。
