SUMMARY:Understanding the Effects of Modern Compressors on the Community E
 arth Science Model
DESCRIPTION:Workshop\n\nUnderstanding the Effects of Modern Compressors on
  the Community Earth Science Model\n\nUnderwood, Bessac, Di, Cappello\n\nT
 he Community Earth Science Model (CESM) is an important tool in climate mo
 deling that produces a large volume of data on each simulation.  Researche
 rs have increasingly been turning to both lossless and lossy compression a
 s an approach to reduce the volume of data for the CESM climate applicatio
 ns. However, it is non-trivial for users to choose the best-qualified comp
 ressor especially because of the advent of many modern lossless and lossy 
 compressors and complicated scientific integrity assessment of climate dat
 a model.  In this paper, we evaluate 11 state-of-the-art compressors using
  the quality metrics developed by climate scientists to understand the eff
 ectiveness of the compressors on the CESM climate datasets with 4 four dif
 ferent models. Our work also discloses the best compression ratio that can
  be reasonably achieved while meeting these strict quality requirements.\n
