| Abstract: | 本整合計畫擬完成兩年前向科技部申請建置流星雷尚未完成的工作。利用此專業操作型流星雷達，配合福衛七號GPS電波掩星法所量得的散塊E層資料，以及新建置完成的中壢電離層觀測儀(Ionosonde)和現有的中壢特高頻雷達等的觀測結果，進行下述研究工作：(1)完成中壢流星雷達的建置，觀測並研究低電離層(MLT Region，80-120km)內的中性風與大氣潮汐現象，並探究低層/高層大氣的耦合現象; (2)利用福衛七號GPS電波掩星技術、中壢特高頻雷達、電離層觀測儀、與中壢流星雷達共同觀測Es層，研究電離層散塊E層的形成機制; (3)研究Es層3公尺場列不規則體團狀與層狀三維空間結構的成因; (4)利用中壢特高頻雷達、流星雷達與電離層觀測儀探究流星發生事件對於電離層散塊E層形成的貢獻與影響; (5)設置資料平台與資料分送機制，並與大氣學門資料庫連結，將本流星雷達所觀測到的資料納入資料平台中，提供國內外學者使用。 ;In this integrated project, we plan to continue the works of building a new meter radar that was proposed to MOST two years ago, which is expected to be installed at Chung-Li ionosonde station. With this professional, operational meteor radar combined with the ionospheric data obtained by FORMOSAT-7, Chung-Li VHF radar, meteor radar, and ionosonde, an attempt is made to study the following unresolved issues associated with ionospheric Es layer: (1) Using the underdense meteor echoes detected by the meteor radar, we plan not only to observe and study neutral wind and atmospheric tide in Mesospheric and Lower Ionosphere (MLT) region, but also to investigate the lower/upper atmospheric coupling; (2) We plan to use FORMOSAT-3 in combination with Chung-Li VHF radar, Chung-Li ionospnde, and meteor radar to study the formation mechanism of ionospheric Es layer and to clarify the roles played by the neutral wind, electric field, and plasma instability in the formation of the Es layer; (3) On the basis of data collected by FORMOSAT-3, VHF radar, ionosonde, and meteor radar, we plan to clarify the physical factors that dominate the formations of blob and layer types of the Es layer; (4) With the same data sat, we would like to study the long-term relation between occurrences of the Es layer and the meteor trails, including seasonal and annual variations; (5) A database platform and data distribution procedure will be established in this project. In addition to the neutral wind, temperature, diffusive coefficient in MLT region obtained by the operational meteor radar, the other ionospheric data observed by other radars will be also archived in the database or the use of scientist to investigate ionosphere and MLT region. |
