<div dir="ltr">Dear Colleagues,<br><br>We would like to invite you to attend
the following CEDAR session on using the NCAR Whole Atmosphere
Community Climate Model - eXtended (WACCM-X), scheduled for 4-6pm on
Thursday, June 22:<br><br><span style="color:rgb(0,0,0);font-family:sans-serif;font-size:12.7px;font-style:normal;font-variant-caps:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);display:inline;float:none">The NCAR Whole Atmosphere Community Climate Model - eXtended (WACCM-X) is a general circulation model that spans the altitude range from the Earth’s surface to the exobase, including the thermosphere and ionosphere. Recent developments are the implementation of an interactive ionospheric dynamo solver and F-region ion transport. Together with the previously implemented interactive ion-chemistry, time-dependent electron and ion temperature solver, and high-latitude inputs, WACCM-X now has a fully functional and interactive ionosphere. This new version of WACCM-X is one of the atmospheric components of the NCAR Community Earth System Model version 2 (CESM2). This workshop will provide an overview of WACCM-X, presentations of some recent results illustrating its new capability, basic tutorials on how to use it, and a discussion of new development priorities. This is an opportunity for members of the community to learn about the model and also to make recommendations about where it should go next.<br><br></span><div>Session information can also be found at:<br><a href="http://cedarweb.vsp.ucar.edu/wiki/index.php/2017_Workshop:WACCM_X_Users_Group" target="_blank">http://cedarweb.vsp.ucar.edu/<wbr>wiki/index.php/2017_Workshop:<wbr>WACCM_X_Users_Group</a><br><br></div><div>Sincerely,<br><br></div><div>Hanli Liu<br></div><div>Dan Marsh<br></div>Stan Solomon</div>
