What is the Accuracy of the Total Irradiance Monitor?
Abstract
The Total Irradiance Monitor (TIM) on NASA's SOlar Radiation and Climate Experiment (SORCE) is the most recently launched instrument to monitor the total solar irradiance (TSI). We present results from the first of the TIM's five years of operations and discuss the current knowledge of the instrument's accuracy. To date, we find the four instrument channels in good agreement and extremely robust against solar exposure. Such instrument characterizations and measurement accuracies influence the observational scenarios appropriate for determining long-term solar variability, and currently favor overlapping measurements of very stable TSI-monitoring instruments.
