In this paper, we show benchmarking results of the Pangeo platform on two di erent HPC sys- tems. Four di erent geoscience operations were considered in this bench- marking study with varying chunk sizes and chunking schemes. Both strong and weak scaling analyses were performed. Chunk sizes between 64MB to 512MB were considered, with the best scalability obtained for 512MB. Compared to certain manual chunking schemes, the auto chunk- ing scheme scaled well.
