Migrating Tides in the Stratosphere from COSMIC Radio Occultation Data

These analyses of the migrating tides in temperature, microwave refractivity, and geopotential in the Earth’s stratosphere are analyzed using GPS radio occultation (RO) data obtained by the COSMIC constellation of six satellites in orbit planes separated by 30° in ascending node. The tides are analyzed monthly, beginning with November 2006 and ending with December 2016. The radio occultation retrievals used as input to the analyses are obtained from the Climate Data Record v1 of the EUMETSAT Radio Occultation Meteorology Satellite Application Facility (ROM SAF; romsaf.org). The reference model that is used for the sake of comparison are the 3-, 6-, 9-, and 12-hr forecasts of the ERA-Interim reanalysis project.本数据集针对地球平流层内温度、微波折射率与位势的迁移潮汐展开分析，所用观测数据由轨道平面升交点间隔30°的6颗卫星组成的COSMIC星座获取的GPS无线电掩星（Radio Occultation, RO）数据。潮汐分析按月进行，时间范围为2006年11月至2016年12月。本分析的输入数据为无线电掩星反演结果，源自欧洲气象卫星应用组织（EUMETSAT）无线电掩星气象卫星应用设施（ROM SAF；romsaf.org）发布的气候数据记录v1版本。用于对照验证的参考模型为ERA-Interim再分析项目的3小时、6小时、9小时及12小时预报产品。
