Emissivity spectra retrieved from airborne observations collected during the MACSSIMIZE field campaign Kirsty Wivell, Stuart Fox, and Chawn Harlow

MACSSIMIZE: in-situ airborne observations by the FAAM BAE-146 aircraft Facility for Airborne Atmospheric Measurements; Natural Environment Research Council; Met Office

Short summary
Satellite microwave observations improve weather forecasts, but to use these observations in the Arctic, snow emission must be known. This study uses airborne and in situ snow observations to validate emissivity simulations for two- and three-layer snowpacks at key frequencies for weather prediction. We assess the impact of thickness, grain size and density in key snow layers, which will help inform development of physical snow models that provide snow profile input to emissivity simulations.
