We aim to facilitate the adoption of lossy compression in the geoscience community by making it easier to identify optimal compression parameter settings, and this dataset was generated to support that effort. In particular, this data was used to develop and evaluate an approach for creating models to predict optimal compression parameter settings and identify features that are useful for determining the compressibility of a particular output variable. We provide a subset of daily 2D atmospheric variables from the CESM1 LENS data compressed with the popular ZFP compressor. We also provide compression metrics for all of the compressed datasets and feature values for the original data (that can be used for model training, for example). completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral CESM > NCAR Community Earth System Model U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-10-28 revision 25.1 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-10-28 revision 25.1 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 1.25 eng utf-8 climatologyMeteorologyAtmosphere -180.0 180.0 -90.0 90.0 1920-01-01T0000+00 1974-10-08T0000+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 14453.448 https://gdex.ucar.edu/datasets/d573432/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d573432/dataaccess/ https Data Access Related Link download none asNeeded
