The Earth Radiation Budget Experiment consists of an array of radiometric instruments placed in earth orbit by the National Aeronautics and Space Administration to monitor the longwave and visible components of the earth's radiation budget. Presented is a dynamic electrothermal model of the active cavity radiometer used to measure the earth's total radiative exitance. Radiative exchange is modeled using the Monte Carlo method and transient conduction is treated using the finite element method. Also included is the feedback circuit which controls electrical substitution heating of the cavity. The model is shown to accurately predict the dynamic response of the instrument during solar calibration.
地球辐射收支实验由美国国家航空航天局放置在地球轨道上的一系列辐射测量仪器组成，用于监测地球辐射收支的长波和可见光分量。本文介绍了一种用于测量地球总辐射出射度的有源腔辐射计的动态电热模型。辐射交换采用蒙特卡罗方法建模，瞬态传导采用有限元方法处理。模型还包括控制腔体电替代加热的反馈电路。结果表明，该模型能够准确预测仪器在太阳校准期间的动态响应。
