Paper Abstract

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 shortwave components of the Earth's radiative budget. Presented is a high-level dynamic electrothermal model of the nonscanning Earth-viewing active cavity radiometers used to measure the Earth's total radiative exitance. High accuracy is obtained by integrating an optical and thermal radiative model with both a transient conduction model of the SuprasilR filter dome and a dynamic electrothermal model of the active cavity. The instrument optical and thermal radiative performance is characterized by a Monte-Carlo ray- trace representation. Thermal diffusion in the SuprasilR filter dome is modeled by a three-dimensional transient finite difference analysis. Dynamic electrothermal behavior of the active cavity is described by a two-dimensional transient finite element model. The paper emphasizes the capabilities of the current models, including the ability to perform simulated calibration runs and to simulate the so-called `solar blip' phenomenon.
