Development of a LiDAR for Low-Altitude Gust Measurements
Abstract
The first part of the project is to join an AFRL-NCU cooperative research project of CRADA (Collaboration Research and Development Arrangement) initiated by Dr. Jonah Colman of AFRL. A 5x5x7 antenna and the receiving system will be installed in Southern Taiwan to make a long base line bi-static oblique ionospheric sounding system to receive the reflected signals transmitted from other ionosonde stations such as at Guam and-or CODARs (Coastal Ocean Dynamics Applications Radars) stations. The system can study the ionospheric average background density and its extreme variations such as sporadic E and spread F events that are observed in the western Pacific regions where no ground ionosonde stations are available. The ionospheric specifications will be compared with FORMOSAT-7-COSMIC-II (FS-7-COSMIC-II) GPS RO derived ionosphere profile and with our NCU TWIM 2 (TaiWan Ionosphere Model 2) model that is being upgraded from using FS-7-COSMIC-II GPS RO data. The second part of the project is to construct a global-seasonal scintillation map using the recently launched FS-7-COSMIC-II GPS RO signals and other in-situ measured density data from Taiwan cubesat programs during the ascending phase of solar cycle of 25. The obtained global-seasonal scintillation maps will be used to compare with previously published scintillation maps constructed with FS-3-COSMIC data obtained in the decline phase of solar cycle 23. The results of the study are presented first in the Fall AGU meeting and other scientific assembly, and then written into papers to publish in different scientific journals.
