项目摘要
9123150 Kundu This project will determine the frequency of maximum correlation of the solar microwave flux with the total solar irradiance, and to obtain statistical evidence regarding the sources of the correlation. The goals are to overcome some of the failure of the 2800 MHz microwave flux to provide adequate proxy data for irradiance measurements, and to use the additional information in multi-frequency data to reveal the physical reasons for the presence or absence of certain correlations. Using the solar flux data at 1000, 2000, 3750 and 9400 MHz from Toyokawa Observatory, along with the 2800 MHz flux data from Ottawa, the PI will correlate the microwave observations with irradiance measurements obtained by The Active Cavity Radiometer Irradiance Monitor (ACRIM) aboard the Solar Maximum Mission (SMM). The project will model the microwave flux spectrum in the 1000-9400 MHz range in order to extract its principal (sunspot, coronal and chromospheric) components. Using the known associations of these spectral components with optical observations, the PI will obtain their relative normalizations so that the components may be identified from the microwave measurements alone. Finally, the PI will obtain the optimum functional relationships by which the microwave flux spectrum can be used as a proxy for solar irradiance. ***
小行星9123150 该项目将确定太阳微波通量与太阳总辐照度的最大相关频率,并获取关于相关性来源的统计证据。 目标是克服2800兆赫微波通量的一些故障,为辐照度测量提供足够的替代数据,并使用多频数据中的额外信息来揭示某些相关性存在或不存在的物理原因。 利用来自丰川天文台的1000、2000、3750和9400 MHz的太阳通量数据,沿着来自渥太华的2800 MHz通量数据,PI将把微波观测结果与太阳最大值使命(SMM)上的有源腔辐射计辐照度监测器(ACRIM)获得的辐照度测量结果相关联。 该项目将模拟1,000 - 9,400兆赫范围内的微波通量谱,以提取其主要组成部分(太阳黑子、日冕和色球)。 利用这些光谱分量与光学观测的已知关联,PI将获得它们的相对归一化,以便可以仅从微波测量中识别这些分量。 最后,PI将获得最佳的函数关系,微波通量谱可以用作太阳辐照度的代理。 ***
