Running Tools on GHub


The GHub gateway pilots software tools for scientists to investigate new metrics for model-data comparison and for model assessment. Workflows will also be developed using open-source Pegasus software, using new timeseries datasets to enable quantification of model uncertainties.

Ice Sheet tools

The Ice Sheet tools hosted on GHub were developed especially to validate ice sheet model data and can be used with either Greenland or Antarctic data. These tools, which run in Jupyter Notebooks, have been developed to check and verify models from the ISMIP6 data release.

About CmCt

The Cryosphere model Comparison tool (CmCt) ice sheet model validation tool was developed by NASA to facilitate direct comparison between satellite observational data and ice sheet models. It utilizes several decades of satellite-based observations from Greenland and Antarctica.

Currently, the CmCt is used to compare ice sheet models to remotely sensed satellite ICESat (Ice, Cloud, and land Elevation Satellite) laser altimetry, ERS-1, ERS-2, and Envisat radar altimetry data, and GRACE (Gravity Recovery and Climate Experiment) satellite data. For comparison with GRACE data, ice sheet models can also be compared with either GRACE Mascon or Spherical Harmonics solutions. The CmCt works for Greenland and Antarctica submissions.
