Comparison of transmittance and transmission spectra measured by the radiometers attached to the remotely operated vehicle (ROV) and to autonomous radiation stations34,55: (a) 02/05/2020, (b) 09/05/2020, and (c) 29/08/2020. Grey lines are selected ROV transmittance and transmission spectra for different ice types. Blue lines are mean ROV spectra measured at the radiation stations. Red lines are spectra from the radiation stations: 2020R14 (a) was deployed on second-year ice, 2020R13 (c) was deployed on a sea-ice ridge, 2020R22 (d) was deployed on level bare ice. The locations of the radiation stations are shown in Fig. 3a,c.
