LROSE: The Lidar Radar Open Software Environment
The current LROSE release is called “Elle” (a pink blend fragrant rose) and encompasses six key toolsets that define a core lidar/radar workflow: Convert, Display, QC, Grid, Echo, and Winds. Elle 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.
Elle can be compiled in C++ for native apps on Linux or Mac. Preliminary support is available for some tools on Windows.
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.

- Homebrew Installation
- Mac Homebrew installation - For Native applications on the Mac, the recommended method is to use Homebrew. The formula contains all the necessary dependencies and builds instructions.
- Source Installation - Intended for users who wish to do a manual build or build in a non-standard location. Source compilation is best performed using a supplied Python script.
- Build system - For LINUX and MAC OS cmake/autoconf/manual builds and code development
- CIDD Binary Installation
- CIDD Binary Release - CIDD depends on a 32-bit build, which complicates the build and install for the core. The CIDD display application is not included in the standard lrose-core packages (above).
- quick start
- lrose quickstart tutorial - Go over the basics to get up and running quickly with LROSE.
- echo tutorials
- basic elle echo tutorial - Go through the basic steps necessary to convert a raw radar file to CfRadial, calculate Kdp and three-dimensional rain rate, and estimate the surface rainfall. The purpose of this tutorial is to confirm that the install process was successful and that some programs are working.
- basic+ elle echo tutorial - Similar to the basic elle tutorial with the added tasks of downloading GFS analysis from which to estimate a sounding near the radar and running the RadxBeamBlock application.
- full elle echo tutorial - This tutorial assumes the user has radar data downloaded in an acceptable radar format and walks through the most important parameters that need to be edited to run the Quantitative Precipitation Estimation (QPE) workflow.
- grid tutorial
- elle regrid and convective/stratiform tutorial - Convert raw NEXRAD data to the cfradial format and then interpolate to a cartesian grid and applies a convective stratiform separation algorithm.
- wind tutorial
- VORTRAC tutorial - run VORTRAC to retrieve the winds using the GBVTD/GVTD algorithm from a single Doppler radar data.
- CSU Radartools tutorial
- CSU-Radartools tutorial - Step through the processing of a raw radar file through editing, QC and gridding using LROSE and CSU-Radartools
- Airborne radar navigation correction tutorial
