Interview with Ron Gelaro, Lead Scientist for Atmospheric Data Assimilation at NASA’s Global Modeling and Assimilation Office and NASA/GMAO representative on the JCSDA Executive Team

At NASA’s Global Modeling and Assimilation Office (GMAO) weather prediction is as much an operational endeavor as a research one, with a NWP model run daily that produces forecasts for NASA customers and missions. The team that designs and runs that model is one of JCSDA’s integral partners, both providing input and putting JCSDA innovations like the JEDI unified data assimilation framework into operational practice.

The JCSDA is pleased to announce the release of Skylab 4.0!

JCSDA SkyLab 4.0 is the fourth roll-up release that provides integrated Earth System Data Assimilation capability via a unified end-to-end ecosystem including a single code build, workflow, data store, and diagnostics dashboard. Initial capabilities are demonstrated for the following components: atmosphere, ocean, sea-ice, soil moisture, snow, aerosols, and composition. The diagnostics dashboard is available at https://skylab.jcsda.org    

The main SkyLab upgrades for release 4.0 include:

  • Atmosphere-land experiment:

    • Updated observation converters for AMV satellite wind, ATMS, and TROPICS

    • Correlated observation errors for IASI and CRIS

  • Trace gas experiment:

    • CO and NO2 3DVar assimilation from TropOMI NO2 tropospheric columns, TropOMI CO total columns and MOPITT CO total columns observations. 

  • Software infrastructure 

    • Environment to build: all libraries on SPACK-STACK 1.3.0

    • Observation API: significant gains in I/O efficiency with IODA v.2.5

  • Support is extended to the following system requirements:

    • Amazon Web Services (AWS) Single Node AMI (RedHat 8)

    • Amazon Web Services (AWS) Parallel Cluster (Ubuntu 20.04)

    • NASA Discover (gnu & intel)

    • NOAA Mississippi State University Orion (gnu & intel)

    • NOAA University of Wisconsin S4 (gnu & intel)

    • NCAR Cheyenne (gnu & intel)

SkyLab has been developed by the JCSDA with contributions from its Partner Agencies in NOAA, NASA, the US Air Force, and the US Navy.
