LROSE

The Lidar Radar Open Software Environment

DOI

The current LROSE release is called “Cyclone” (a bright red rose) and encompasses six key toolsets that define a core lidar/radar workflow: Convert, Display, QC, Grid, Echo, and Winds

Blaze can be used from a ‘Virtual Toolbox’ using Docker and a wrapper script, or compiled in C++ for native apps on Linux or Mac. Preliminary support is available for some tools on Windows.

Full documentation for Cyclone is available on the LROSE website

We encourage users to register in order to receive critical software updates, and sign up for the mailing list to help build the LROSE community.

Help can be obtained by posting issues directly to the lrose-cyclone Github repository, via our help mailing list, or Discourse user forum.

LROSE is a co-operative project between:

• Dept. of Atmospheric Science at Colorado State University (CSU) and the
• The Earth Observing Lab at the National Center for Atmospheric Research (NCAR).

LROSE is funded by the National Science Foundation.

Cyclone focuses on high-quality, well-tested, well-maintained and well-documented key applications as ‘building blocks’, allowing users to assemble trusted, reproducible workflows to accomplish more complex scientific tasks.

In the current release, the following tools are available:

Convert

• RadxPrint - Query files to determine properties and support by the Radx engine
• RadxConvert - Convert 24 different lidar and radar formats to CfRadial NetCDF format
• RadxBufr - Convert Bufr format to CfRadial NetCDF format

Display

• HawkEye - Real-time and archive display suitable for both scanning and vertically pointing radars.

Quality Control

• RadxDiffFields - Compare two fields in different CfRadial files
• RadxDiffVol - Compare two volumes in different CfRadial files
• RadxMergeFields - Merge fields from different CfRadial files
• RadxFilter - Perform simple filtering operations
• RadxPersistentClutter - Create a mask for persistent ground clutter

Grid

• Radx2Grid - Gridding and interpolation of ground-based radar data

Echo
