Most components are working stably now and the remaining pieces (e.g. verification) are now being tested. I am also now beginning to engage with beta-testers to confirm they can reproduce what I am able to build/run. There are many pieces of the system that need to get into their final forms still (a.k.a. validated and tagged) so we're still at least a couple weeks away from a finalized system. We have to cross our Ts and dot our Is before giving you all a package to run on Hera.</div><div><br></div><div>Given the current status I estimate an official tagged and merged version in global-workflow by mid to late October. I'm working to have a branch version for folks to use in early October, with the understanding that changes will likely still occur during final pre-commit testing phase. Stay tuned for that!</div><div><br></div><div><b><font color="#38761d">Some other good news...word on the street is that the schedule for Theia end-of-life has been extended into late October, <i>maybe</i> even late November!</font></b> I'm waiting for system admins to send an announcement about this to confirm what I was told yesterday. If you have experiments running on Theia that will complete in the next few weeks I recommend trying to finish them there. Even though end-of-life has been extended for Theia the filesystem support will still go away October 1st so keep that in mind...if there are filesystem issues there is no help. <b><font color="#38761d">Hera has now passed acceptance tests and is considered operational, although it's still at 50% while Theia is still available.</font></b><br></div><div><br></div><div><b><font color="#ff0000">One important thing to keep in mind for those considering moving incomplete experiments from Theia to Hera...the version of the FV3GFS components being tested on Hera are off of the respective component master/develop branches. </font></b>This means that when updates for Hera come back to global-workflow it will be more advanced that GFSv15 and the develop branch will no longer reproduce current operations. Please take a look at the component versions you are using in your experiments on Theia and see if you can move to the latest versions (sync merge with the master/develop to get build updates when available) or if you will need build patches for your older versions. This check will be most critical for the DA and forecast parts of the FV3GFS.</div><div><br></div><div>Thanks all, we're getting close to the end of this port!
