RDA/RPG Build 22.0:
RDA/RPG is primarily a migration of Red Hat Enterprise Linux (RHEL) 7 to RHEL 8 but also includes numerous bug fixes and minor enhancements.
Build 22 will include improvements to the FAA's Icing Hazards Layers (IHL), and the Super-Resolution Data-Quality Edited Algorithm and Product (SRQ).
Build 22 will remove Clear Air VCP 32 from the baseline. Site-specific VCPs are being added for Paducah, KY (Base Tilt of 0.3 deg elevation), Pendleton, OR (Base Tilt of 0.2 deg elevation), Springfield, MO (Base Tilt of 0.2 deg elevation), Corpus Christi, TX (Base Tilt of 0.3 deg elevation), and Grand Junction, CO (Base Tilt of 0.0 deg elevation).
Build 22 will include improvements to the velocity dealiasing algorithm in environments of high shear. It also includes changes to support long-term software maintenance.
Build 22 adds an RDA Control Command to turn off the sending of RDA logs to the RPG. This could be used to reduce wideband utilization during heavy wideband loads. RDA logs are currently sent from the RPG to the ROC via LDM to support field operations and troubleshooting.
Build 22 adds minor improvements to the SZ2 algorithm used in VCPs 212, 215, 112, and 35. A new Correlation Coefficient estimator is being added to the baseline as well as non-operational.
Build 22 will include full support for the Receiver/Signal Processor (RSP) replacement. This allows for the RSP deployment schedule to be untied to Build 22 software deployment.
Build 22 will automate the Default Storm Speed/Direction from Model Data. The update time will be displayed on the RPG HCI Environmental Data Editor and included in the Shift Change Checklist (SCC) product.
Build 22 will apply the RPG estimate of Initial System Differential Phase (ISDP) in the DP preprocessor by default.
Build 22 will generate the Super Resolution Digital Velocity product (154) on all elevation angles of the VCP. The products above the split cuts will be identical to the Digital Velocity product (99).
Build 22 is currently in formal Operations Test and is scheduled to be released to the field in the Winter, 2023.
