Highlights

• OSX support - homebrew installs tested on BigSur and Monterey.
• Packages are available for Centos, Ubuntu, Fedora 32, 33, 34, Alma Linux, Suse.
• RadxConvert now supports reading OU Raxpol files.
• The cmake-based build option is available.
• Only dependent on the HDF5 C library, the C++ library is now included in libs/Ncxx in LROSE.
• HawkEdit is more mature, and has undergone considerable testing from users.
• Added ECCO algorithm for convective/stratiform partitioning from 3D radar reflectivity.

Wind analysis applications

In this release, we have bundled the wind-related applications along with the core. SAMURAI has undergone significant performance enhancements to speed-up runtime, including support to run on HPC clusters, optimization for single-node performance, implementing a more efficient nonlinear optimization routine using a truncated Newton solver, and enabling the use of GPUs.

These apps are:

• fractl - geometry-based analysis for multi-Doppler wind retrieval
• samurai - variational analysis for multi-Doppler wind retrieval
• vortrac - Vortex Object Radar Tracking and Circulation

The code for these apps may be found at:

Installing from LINUX packages

For most common LINUX systems, you can install lrose from the binary packages on this page.

Installing on Mac OSX using brew

$ brew uninstall lrose-core
$ brew uninstall lrose-blaze
$ brew uninstall lrose-cyclone
$ brew uninstall lrose-elle

Then, install lrose-topaz (after downloading the formula lrose-core.rb)

$ brew install lrose-core.rb

To install fractl, vortrac and samurai using brew, download and run the following commands in a terminal:

$ brew install lrose-fractl.rb
$ brew install lrose-vortrac.rb
$ brew install lrose-samurai.rb

Installing display apps on Mac OSX using disk images

There are three disk images for MacOS:

• vortrac.dmg : Vortex Object Radar Tracking and Circulation
• HawkEye.dmg: HawkEye polar radar display
• HawkEdit.dmg: HawkEye with soloii-like editing capability

To install a disk image file (.dmg), download the .dmg file to your computer. Click on the .dmg file, and drag the application to your Applications folder. The first time you start one of the LROSE applications, it may appear as a Mac app from an unidentified developer. The application is signed by UCAR. Follow these steps:

• Control-click the app icon, then choose Open from the shortcut menu.
• Click Open. The app is saved as an exception to your security settings. You can open the app in the future by double-clicking the icon.
