Cimatology of planetary waves seen in ionospheric F-region pertubations using TEC of GPS (CTW-TEC)

将对德国航天中心诺伊斯特雷利茨定期制作的北方和南半球中高纬度和极高纬度地区垂直电子总含量区域图进行研究，以研究几天周期范围内的行星波。将利用从电离层探测仪和德国地球科学卫星CHAMP上的电离层无线电掩星全球定位系统测量结果获得的垂直电子密度剖面图来验证这些结果。一个PW在两个半球的气候学将被构建和半球的差异将被调查。将使用一个简单的环流模型对中层大气中的行星波进行数值模拟，并将分析潮汐调制对行星波效应穿透热层的影响，以澄清其在中层大气-热层-电离层行星波之间可能的联系中的作用。

Regional maps of the vertical Total Electron Content (TEC) over the northern and southern hemisphere higher middle and polar latitudes that are regularly produced by DLR Neustrelitz will be investigated with respect to planetary waves (PW) in the period range of several days. The results will be validated using vertical electron density profiles obtained from ionosondes and from ionospheric radio occultation (IRO) GPS measurements onboard the German geoscience satellite CHAMP. A climatology of PW in both hemispheres will be constructed and the hemispheric differences will be investigated. Numerical modelling of PW in the middle atmosphere will be performed using a simple circulation model, and the impact of tidal modulation on the penetration of PW effects into the thermosphere will be analysed to clarify its role in a possible connection of middle atmosphere-thermosphere-ionosphere planetary waves.
