N-ICE2015 surface and under-ice spectral shortwave radiation data
This data set contains spectral shortwave radiation data (incident, reflected and transmitted) from two different sites: time-series from a fixed site on Floe 3 and 4, so called "supersite", and from point measurements from a "refrozen lead" during drift of Floe 3. #### Supersite...
