N1 - ACKNOWLEDGEMENTS
William D. Harcourt would like to thank PhD studentship funding from SAGES and EPSRC (grant number: EP/R513337/1). Funding for the Svalbard data was provided by a grant from the Research Council of Norway, project number 291644, Svalbard Integrated Arctic Earth Observing System – Knowledge Centre, operational phase, as well as from the RGS, SAGES, and the University of St Andrews. We would like to thank Guido Luiz (Centre Tecnol`ogic de Telecomunicacions de Catalunya (CTTC), GBSAR) and one anoymous reviewer for their constructive reviews of our manuscript. Data reported in this study will be made available within the next 2 years

N2 - Close-range sensors are employed to observe glaciological processes that operate over short timescales (e.g. iceberg calving, glacial lake outburst floods, diurnal surface melting). However, in poor weather conditions optical instruments fail whilst the operation of radar systems below 17 GHz do not have sufficient angular resolution to map glacier surfaces in detail. This letter reviews the potential of millimetre-wave radar at 94 GHz to obtain high resolution 3D measurements of glaciers in most weather conditions. We discuss the theory of 94 GHz radar for glaciology studies, demonstrate its potential to map a glacier calving front, and summarise future research priorities.
