Short summary

This study investigates the required accuracy of radiometric calibration sources for remote sensing instruments to properly resolve decadal trends of climate relevant trace species like ozone, water vapor and temperature. The required temperature knowledge of the calibration source is in the order of 100 mK. This is demonstrated by a Monte Carlo simulation. The results are confirmed using real measurements acquired by the GLORIA instrument.
