Another Arctic Blast in the East; Eastern U.S. Winter Storm

A powerful Arctic blast will bring dangerously cold, record low temperatures to the upper Ohio Valley, Mid-Atlantic, Gulf Coast and Southeast U.S. this weekend. A rapidly deepening storm will produce widespread heavy snow and wind from the southern Appalachians across the Carolinas and southern Virginia into Sunday. Storm-force winds and coastal flooding will be possible along the East Coast. Read More >

CODE B24.0r1.20

 

Build 24 - What's New?

  1. For QPE, Vertical Profile of Reflectivity Correction (VPRC) is on by default.  Also, improvements to R(A), R(Z) and R(Z,ZDR) rain rate equations.
  2. Long-Term Average Reflectivity (LTAR) input to the Hydrometeor Classification Algorithm (HCA) to flag persistent ground clutter is available when activated in the HCI and LTAR product display available in HCI Clutter Regions Editor window. Note that LTAR takes 30 days of accumulation before HCA will use it.
  3. Range-Defined Quasi-Vertical Profile products are available for reflectivity, correlation coefficient, differential reflectivity and specific differential phase.
  4. Removal of VCP 31.
  5. Numerous bug fixes

 

 

Only the Linux PC platform is currently supported for CODE.

Red Hat 8 is the official operating system for ORPG while CentOS Stream is a good alternative operating system for CODE.

General Notes:

Do not attempt to compile the ORPG source code without meeting the system requirements stated below.

  • Attempting to use any version of Linux other than Red Hat Enterprise 8 Desktop with Workstation option or CentOS Stream Desktop
  • Attempting to use versions of compilers not listed will require changes to the source code and perhaps modification of makefiles.

 

Workstation Platform

 

The Operational Configuration provides a development platform that is essentially the same as the operational system. This is not required for algorithm development or implementation. The Development Configuration provides an acceptable platform for running an ORPG clone and developing ORPG algorithms but does not match the performance criteria of the operational system.

Performance Testing. Any desktop PC with a current processor and 2 GB of RAM would be sufficient in order to determine the relative performance of an algorithm.

  Operational Configuration (Note 1) Development Configuration       Notes
Workstation AMD Opteron 250 Dual Processor Any PC with a Pentium 4 or equivalent processor.  
Operating System Red Hat Enterprise 8 Desktop with Workstation Option (64-bit) Red Hat Enterprise 8 Desktop with Workstation Option (64-bit) or CentOS Stream Desktop 2 
Physical Memory 2 GB 1 GB RAM minimum
2 GB recommended		  
Swap Space TBD 1 GB minimum 3 
Disk Drive serial ATA drives 1 GB plus for each ORPG account   4 
Display Capability N/A 24-Bit color, 1024x768 min, 1280x1024 recommended  

 

Note 1: With the amount of overhead in the operational system there is little reason to replicate it for development. Any recent quality desktop PC with 2 GB of RAM can be used to obtain a good idea of an algorithms relative performance.
Note 2: Red Hat Enterprise 8 Workstation has been selected as the operating system for the deployed ORPG. The ORPG software will compile as 64-bit or 32-bit.  CentOS Stream has been tested to be a good alternative Operating System of Red Hat 8.
Note 3: Currently 1 GB of swap space is sufficient for the CODE development environment.
Note 4: Does not include space for compilers and other development tools.

 

Software Language Compilers

 

The CODE Linux platform uses libraries and software development tools that are provided with the basic distribution of Red Hat Enterprise 8 Desktop with Workstation option.

Compilers used to build the Operational ORPG

  • Compilers and utilities provided with Red Hat Enterprise Workstation
    • GCC 4.1.2 (includes gcc, g++, and gfortran)
    • GNU make 3.81-1.1
    • GNU linker in binutils 2.17.50.0.6-5
    • glibc 2.5-18
