Theoretical Study of the Photochemistry, Energetics and Dynamics of the Thermosphere in Support of the CEDAR Program

空气动力学研究的一个目标是能够通过对气辉发射线的地面测量来确定高层大气不同区域的特性。参与这项工作的主要研究人员通过他们过去的工作，通过对黄昏气辉线的地面测量确定热层组成、温度和入射EUV通量，朝着这一目标取得了重大进展；然而，在解决所涉及的复杂理论建模和数据获取问题方面，仍有许多工作要做。拟议的工作是为实现这一目标而精心计划的研究的继续进行。在卫星测量的佐证支持下，将继续开发与可获得的地面气辉测量有关的模型。开发的模型将进行升级，使之便于用户使用，供雪松光谱学社区使用。这些模型将进一步修改和改进，以纳入非相干雷达或电离层探空测量，并将其射程扩大到全球范围。***

One goal of research in aeronomy is to be able to determine the properties of various regions of the upper atmosphere from ground-based measurements of airglow emission lines. The principal investigators involved in this work have made significant progress towards this goal through their past work in determining thermospheric composition, temperature, and incident EUV flux from ground-based measurements of twilight airglow lines; however much remains to be done to solve the complex theoretical modelling and data acquisition problems involved. The proposed work is a carefully planned continuation of research aimed at advancing towards the goal. Development of models relating to attainable ground based airglow measurements will continue, with corroborative support from satellite measurements. The models developed will be upgraded and made user friendly for use by the CEDAR spectroscopy community. The models will further be modified and improved to incorporate incoherent radar or ionosonde measurements, and to extend their range to a global scope. ***
