Furthermore, those who respond to this RFI should not anticipate feedback with regards to its submission; other than acknowledgment of receipt - ONLY IF a request for an acknowledgement is requested by the submitter. This RFI does not commit the Government to contract for any supply or service. The National Oceanic and Atmospheric Administration (NOAA) is not seeking proposals at this time. Responders are advised that the U.S. Government will not pay any costs incurred in response to this RFI. All costs associated with responding to this RFI will be solely at the interested party's expense. Not responding to this RFI does not preclude participation in any future solicitation. The information provided in this RFI is subject to change and is not binding on the Government. All submissions become the property of the Federal Government, and will not be returned. Any information that the vendor considers proprietary should be clearly marked as such. 1. Purpose of this RFI: NOAA is seeking to gather ideas, recommendations, and best practices from industry on how to advance weather surveillance radar technologies. NOAA has developed a preliminary plan to replace the Next Generation Weather Radar (NEXRAD) Program Weather Surveillance Radar � 1988 Doppler (WSR-88D) by 2040 as described in the 2020 Report to Congress: Weather Radar Follow-On Plan: Research and Risk Reduction to Inform Acquisition Decisions (attachment A) that is focusing our current efforts. 2. Background: NOAA has been a leader in developing weather surveillance radar technology, which has gained widespread use in the government and commercial sectors around the world. NOAA research has led to the development of the WSR-88D, which is arguably the premier operational weather surveillance radar in existence today. WSR-88D is the primary tool used by weather forecasters to provide warnings for severe weather (e.g., tornadoes, hail, strong winds), flash flooding, winter weather, and other hazards to aviation. The 2015 NOAA/National Weather Service Radar Functional Requirements (attachment B) are technical specifications for the existing WSR-88D system, but do not necessarily define the full spectrum of technical specifications for a future radar system. The NOAA National Weather Service (NWS) is conducting Service Life Extension Program (SLEP) activities to extend the operational capability of the system until an approximate time frame of 2035, and on-going information technology refresh and sustaining engineering programs will support the continued operation of the WSR-88D network through the 2040 time frame. NOAA will need to make a key decision by 2028 to continue maintaining the current system, or to replace it with a new radar network. Although the WSR-88D underlying technology will be over 50 years old by 2040, it has undergone multiple technology refreshes and upgrades to extend its longevity, such as the addition of dual polarization capability that was completed in 2013. Dual polarization, the ability to transmit and receive both horizontally and vertically polarized signals, provides for vastly improved retrievals of precipitation intensity and type and debris detection to better identify tornadic events. NOAA�s Office of Oceanic and Atmospheric Research (OAR) has been investigating Phased Array Radar (PAR) technology since 2003 to meet mission driven expanded radar requirements to support improved and enhanced weather warnings. PAR is a promising technology that has demonstrated great potential to improve warnings for various types of severe weather, primarily through the use of faster updates and adaptive scanning capabilities. However, there are many technological challenges that must be addressed before PAR technology can serve as a replacement for the WSR-88D system. Chief among these technology challenges is the addition of dual polarization with PAR technology. NOAA, in partnership with the Federal Aviation Administration (FAA), has developed the Advanced Technology Demonstrator (ATD), which is the first dual polarization, S-band PAR developed specifically for weather applications. The ATD is a test system that was installed at NOAA�s National Severe Storms Laboratory (NSSL) in Norman, Oklahoma in 2018 to evaluate dual polarization calibration and performance on PAR technology and to demonstrate advanced scanning techniques for weather radars using PAR. The ATD achieved initial operating capability (IOC) in 2021 and is currently being used to conduct experiments. Development of the ATD has moved PAR technology to a NOAA Readiness Level (RL) 5 for dual polarization meteorological applications (see attachment C for the full RL definition).� Further research and development is needed before NOAA can make a high-confidence decision regarding PAR technology as an appropriate replacement for WSR-88D. Information related to the advancement of PAR is provided in attachments D and E. NOAA has previously investigated the concepts of multiple simultaneous radar transmission strategies based on phased-array antenna array configurations (e.g., cylindrical and multi-face planar configurations) to achieve the faster radar volumetric update rates of 60 seconds expressed as a future objective in the NOAA Radar Surveillance Requirements: Weather (attachment F). NOAA is currently evaluating a rotating planar array configuration and how it may be utilized to improve radar volume update times compared to the traditional mechanically rotating parabolic antennas (which take on the order of 5 minutes to scan the conical volume of space around the radar) typically used for meteorological radar applications. NOAA has developed a research plan to enable the technological progress needed to prepare for a formal Radar Acquisition Management Program (RAMP) beginning in 2028. RAMP will compare the cost-benefit analysis of: 1) sustaining the current system through an additional SLEP; 2) replacing WSR-88D with a new reflector dish, mechanically rotating radar system; or 3) replacing WSR-88D with the promising PAR technology. PAR is one of the main technologies that NOAA is significantly interested in developing further as a potential future replacement for the WSR-88D technology. NSSL anticipates acquiring and implementing a PAR Test Article in the FY23/FY24 timeframe. Experiments and analysis conducted using the planned PAR Test Article will be used to inform future acquisition decisions and analysis of alternatives in RAMP. Information obtained from this RFI will be extremely valuable in developing strategies to advance PAR and will be used to inform future acquisition decisions. Several key assumptions are that the core of the future radar system will be ground based, operate in the S-band, and will provide data commensurate with the NOAA Radar Surveillance Requirements:� Weather (attachment F) (see attachment G for WSR-88D sites). Innovative, cost effective capabilities that meet additional mission driven objective requirements are desirable. 3.� RFI Questions: A. Advanced Weather Surveillance Radar Capabilities.
