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.

该赠款中支持的DOC是测试热层/电离层/电动流动性通用循环模型对上边界条件的敏感性。 他使用现场对齐的间歇性等离子体模型，在模型的上边界处指定电子温度，离子温度和氧离子，这是季节和太阳活动的函数。 将这两个模型与来自Arecibo和Millstone Hill观测值的不连贯的散点雷达数据进行了比较，以评估低纬度和中等纬度的能力。 然后，事后将进行进一步的改进。 对于将来研究大气中可变性的原因，需要对模型对外力和边界条件的敏感性的描述。
