AWIPS 18.2.1 Software Release

AWIPS 18.2.1-1 is a major update to both EDEX and CAVE (on Windows, MacOS, and Centos7/RHEL7). More information is listed below.

  • The linux script has been updated to remove old versions of CAVE and EDEX before installing new versions and backup some /awips2 configuration files.
  • While old versions of CAVE will connect to the new EDEX, the menus will be outdated and we strongly suggest you update CAVE.

EDEX Updates

  • Moved all Satellite, MRMS, and Model menus to EDEX side
    • With the continuing updates to these products, this makes it easier for the menus to be updated on the EDEX side, rather than having every user update their CAVE version
  • Updating/consolidating Satellite menu with new GOES data
    • Menu items only for products that exist (no blank menu items)
    • New GOES East/West Combo products
    • New GOES derived products
    • New GOES RGB products
    • New CIRA Geocolor, Debra Dust, and Cloud/Snow RGB products
    • New derived motion winds for GOES East/West
    • New gridded GLM (Geostationary Lightning Mapper) products for GOES-East (via Dr. Eric Bruning)
    • New GOES-East Vertical Temperature/Dewpoint Profiles
    • New VIIRS data - NOAA20 and SNPP
  • Full MRMS Product Suite (V12.1) decodes and displays
    • Getting products directly from NCO instead of limited product suite on NOAAPort - these are available to all Universities via Unidata’s IDD
    • Products for new areas: Guam, Caribbean, Alaska, and Hawaii
  • New CIMSS ProbSevere product available in CAVE and via Unidata’s IDD
  • New HRRR Smoke products available in CAVE
  • Updates to ldmd.conf and pqact.conf LDM files for new products
  • Moved from Global GFS .25 degree to 1 degree with the latest GFS updates
  • Add menu items for Convective Warnings
  • Added the impact based warning templates into Warngen
  • Updates to the maps database for changes made to counties back in fall of last year

CAVE Updates

  • Added Import GIS option to import shapefiles into CAVE
  • Created WFO and Regional bundle scales for each WFO
  • Removed GEMPAK button

MacOS Specific:

  • Fixed Screen Capture Capability
  • Fixed cross section capability
  • Jep functionality should work for all derived parameters
  • The CAVE installers for Mac are now officially signed and notarized by UCAR and Apple

WARNING: GOES RGB composites are not supported on macOS due to OpenGL Shading Language limitations

Windows Specific:

  • Jep is needed in order to display derived products. We have updated the Windows install instructions to reflect the correct steps as well as created a youtube video to follow along.

Virtual Machine Specific:

WARNING: GOES RGB composites are not supported virtual machines due to OpenGL Shading Language limitations

Thanks much - this is SO much nicer!

The IR/VIS sandwich GOES imagery looks like it's working but then leaves me blank. Is it me?

Posted by Rob Dale on July 14, 2021 at 01:38 PM MDT #

Hi Rob,

What operating system are you running CAVE on? The sandwich product is an RGB product that has limitations on Mac and Virtual Machines (ex. won't render) at this time.

Posted by Tiffany Meyer on July 14, 2021 at 02:38 PM MDT #

Win10 and Centos 7. They both seem to show satellite fine until I try sandwich and get a red error message saying "The resource has been disabled"

This is an amazing new update! I LOVE the satellite features. This will come to great use for the hurricane season since there are many new satellite imagery options. I also like that now there is Impact-based warngen items already coded and I don't have to go through the files. The watches also work properly. The only issue is that the MRMS features are currently not updating.

Hi Wyatt,

Glad you are liking our updates! There was a small issue with MRMS data, but it's been fixed now and you should see data!

The MSI for Win10 won't open on my machine. Any idea what's causing this? The rest of the stuff is working fine.

@Sean Lockhart

In order to open it you have to make sure that the browser does not stop it from downloading. Chrome or chromium based browsers (such as edge) are CTRL+J for the downloads page. Go there and see if it stopped downloading due to a security threat. If that is the case, click "Keep file". Once that launches then Win10 will have an additional security feature blocking the file due to it being an unknown source. Click advanced on the pop-up and click "Run anyways".

I hope this helps.

Enjoying the new update. The satellite data seems to be behind about an hour or two. Do I need to uninstall CAVE and reinstall it?

Posted by Brett Ramirez on October 12, 2021 at 04:20 PM MDT #

Hello Brett,

It is an issue on our end, not you. With the increase in GOES satellite data, our system is having troubles keeping up. We are in the process of installing a new EDEX server that will focus on processing Satellite data and we hope that reduces any latencies. Sorry about the current delays

Posted by Tiffany Meyer on October 12, 2021 at 04:29 PM MDT #

Yeah, I have been having the same issues.
