Abstract:
The time-resolved hyper spectral measurements during MAGIC provide a unique opportunity to study both clouds and aerosols in transition zones between cloudy and clear skies. This presentation presents the spectral-invariant properties of cloud transition zones observed on two cases of July, 2013 using the measurements from the Shortwave Array Spectroradiometer-Zenith (SAS-Ze) and the Solar Spectral Flux Radiometer (SSFR). Though radiance measurements from the two instruments can be different possibly due to the calibration drifting, the spectral-invariant properties observed on the two instruments show some common features. These features indicate that the overall cloud effective particle size likely decreases during the transition from cloudy to clear skies in the two cases.
