CEDAR Post-Doc: Upper Boundary Conditions in the NCAR TIEGCM

本基金资助的博士后正在测试热层/电离层/电动力环流模型对上界条件的敏感性。利用磁场对准的半球间等离子体模型，他指定了模型上界的电子温度、离子温度和氧离子作为季节和太阳活动的函数。将这两种模式与来自Arecibo和Millstone Hill天文台的非相干散射雷达数据进行比较，以评估低纬度和中纬度地区的能力。然后，博士后将进行进一步的改进。这种对模式对外力和边界条件敏感性的描述是今后研究大气变率原因所必需的。

The post-doc supported in this grant is testing the thermosphere/ionosphere/electro-dynamic general circulation model's sensitivity to upper boundary conditions. Using the field-aligned interhemispheric plasma model, he is specifying electron temperature, ion temperature, and oxygen ion at the model's upper boundary as a function of season and solar activity. Both of these models are compared with incoherent scatter radar data from Arecibo and Millstone Hill Observatories to evaluate the capabilities at low and middle latitudes. The post-doc will then make any further refinements. This delineation of the model sensitivity to external forces and boundary conditions is needed for future studies of the causes of variability in the atmosphere.
