Filchner-Ronne melt rates

Using NECKLACE to test satellite data products


Two recent publications have highlighted the value of NECKLACE's field-based measurements of ice shelf melt for testing satellite-derived data products. Vaňková & Nicholls (2022) used measurements from 14 ApRES instruments deployed on the Filchner-Ronne Ice Shelf and found that existing melt rate estimates from satellite data dramatically overestimate the amplitude of inter-annual melt rate variability.

These results were used in Cook et al. (2023) to outline the importance of field-based measurements for validating and improving satellite-derived melt rate data products, and for data assimilation into ice shelf-ocean cavity models. We hope that the first NECLACE dataset will be openly available later this year to support these type of activities.
