Melt rates in Antarctica were estimated using microwave data, achieving a resolution of 6.25 km over nine years.
Data from the Special Sensor Microwave Imager/Sounder demonstrated a correlation with Automatic Weather Station melt estimates (R2 = 0.83).
The empirical model developed establishes a relationship between annual melt days and water-equivalent melt volume.
Findings reveal that microwave estimates are about 15% lower in total melt volume compared to RACMO outputs, suggesting important implications for climate models.
