morning SIP co-chairs. As we announced at the SIP workshop
in April, we have been working towards the release of a
version of our FV3GFS code by May 15. I am pleased to
announce the Version 0 Release of the FV3GFS to the
community through NOAA Virtual Lab (VLab), which was posted
yesterday afternoon. </span><span style="color:windowtext"></span></p>

<p class="MsoNormal" style="margin-bottom:12pt;line-height:normal"><span style="font-size:12pt;font-family:"arial","sans-serif"">NOAA’s
Environmental Modeling Center (EMC) and Geophysical Fluid
Dynamics Lab (GFDL), along with several other partners
including NOAA’s Earth Systems Research Lab (ESRL) and the
Developmental and Testbed Center (DTC) at NCAR, have been
working on developing the Finite Volume Cubed Sphere (FV3)
dynamical core as the Next Generation Global Prediction
System (NGGPS) atmospheric model. FV3 dynamical core
implementation includes incorporating FV3 into the NOAA
Environmental Modeling System (NEMS) and developing
advanced physics and data assimilation techniques to advance
the skill of operational Global Forecast System (GFS). </span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt;line-height:normal"><span style="font-size:12pt;font-family:"arial","sans-serif"">On
Monday May 15, we made an important first step in creating
this new FV3GFS as a community model. This release allows
community users to explore the code and to run forecast-only
experiments for selected cases. Included in this release
are:</span></p>
