Short summary

During volcanic eruptions the presence of ice clouds may affect the volcanic ash signal in infrared satellite measurements. By comparison of measured infrared spectra with spectra from a radiative transfer model including both ash and ice clouds, it is shown that during the Mt Kelud February 2014 eruption, both ash and ice clouds were present simultaneously. The presence of ice clouds lowers the estimated amount of volcanic ash in the atmosphere.
