Snow Melt Onset Over Arctic Sea Ice from SMMR and SSM/I Brightness Temperatures, Version 2

Yearly snow melt onset dates over Arctic sea ice are derived from Scanning Multichannel Microwave Radiometer (SMMR) and Special Sensor Microwave/Imager (SSM/I) brightness temperatures. The introduction of liquid water to snow results in a sharp increase in the emissivity and hence brightness tempera...
