JCSDA SkyLab 2.0 is the second 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. A diagnostics dashboard is available at https://skylab.jcsda.org/

The main SkyLab upgrades for release 2.0 include:

Atmosphere-land experiment:

  • Non-cycling 25 member EDA at C192 resolution. Each member is an FGAT-3DEnVar.

  • More observation types:

    • Synop, METAR,
    • ASCAT,
    • CrIS, IASI,
    • Windborne balloon,
    • Commercial GNSS-RO (including Spire, GeoOptics)

  • Satellite bias correction

Marine experiment:

  • non-cycling 3DVar

  • New 1/4 degree sea-ice/ocean background provided by NOAA/EMC

  • New instruments:

    • sea ice concentration retrievals from SSMIS F17/F18
    • insitu temperature and salinity profiles from NAVY/FNMOC

Composition experiment:

  • H(x) capability from GEOS-CF C90 resolution background

  • New observations:

    • TROPOMI NO2 (tropospheric and total columns) and MOPITT CO (total columns)
    • Aerosol Optical Depth (AOD) from VIIRS NOAA20 and MODIS Terra and Aqua

Turnkey ecosystem for the community to easily reproduce SkyLab on multiple platforms,

  • Environment to build: all libraries on SPACK-STACK 1.1.0

  • Workflow: Generic experiments and suites based on EWOK 0.2.0

  • Data store: >50Tb of observation and model data for Aug 2021 on R2D2 data store 1.1.0

Support is extended to the following system requirements:

  • NOAA Orion (gnu & intel)

  • NASA Discover (gnu & intel)

  • University of Wisconsin S4 (intel)

  • AWS AMI (Ubuntu & RedHat)
