  • Multifunction Phased Array Radar
    MULTIFUNCTION PHASED ARRAY RADAR PROGRAM STATUS AND POTENTIAL SERVICE IMPROVEMENTS Prepared by: Working Group for Multifunction Phased Array Radar (WG/MPAR) August 2009 Office of the Federal Coordinator for Meteorological Services and Supporting Research (OFCM) 8455 Colesville Road, Suite 1500 Silver Spring, MD 20910 Foreword Weather radar has proven its value to the Nation since the installation of the current weather surveillance network began in 1990. In 2020, the WSR-88D radars forming this NEXRAD network will be 23 to 30 years old. In about the same time frame, most of the Nation’s aircraft surveillance radars will be nearing the end of their design life. Decisions on replacing or repairing and upgrading these National radar assets must be made over the next 10 to 15 years. We are now on the threshold of a revolution in civilian radar capability, enabled by the adaptation of established military radar technology to existing civilian applications, plus new capabilities beyond what current systems can provide. The Working Group for Multifunction Phased Array Radar (WG/MPAR) is coordinating an interagency initiative to investigate the feasibility of applying the capabilities of phased array technology to perform weather and aircraft surveillance simultaneously. This paper presents a snapshot of the status of that initiative and projects potential service improvements that would be derived from the operational application of phased array radar to aircraft and weather surveillance. I wish to thank the members of WG/MPAR—especially Dr. James (Jeff) Kimpel, Director of the National Severe Storms Laboratory (NOAA) and Mr. William Benner, Weather Processors Group Manager (FAA)—as well as the OFCM staff, especially Mr.

    ENGINEERING REPORT CONCERNING THE EFFECTS UPON FCC LICENSED RF FACILITIES DUE TO CONSTRUCTION OF THE GREAT PATHFINDER WIND ENERGY PROJECT In BOONE & HAMILTON COUNTIES, IOWA Prepared for Apex Clean Energy Lake Elmo, Minnesota Revised: April 2, 2020 By: B. Benjamin Evans Evans Engineering Solutions (262) 518-0178 Phone www.evansengsolutions.com Great Pathfinder Wind, IA RF Impact Report - Page 1 ENGINEERING REPORT CONCERNING THE EFFECTS UPON FCC LICENSED RF FACILITIES DUE TO CONSTRUCTION OF THE GREAT PATHFINDER WIND ENERGY PROJECT In BOONE AND HAMILTON COUNTIES, IOWA I. INTRODUCTION This engineering report describes the results of a study and analysis to determine the locations of federally-licensed (FCC) microwave and fixed station radio frequency (RF) facilities that may be adversely impacted as a result of the construction of the Great Pathfinder Wind Energy Project in Boone and Hamilton Counties, Iowa. This document describes impact zones and any necessary mitigation procedures, along with recommendations concerning individual wind turbine siting. All illustrations, calculations and conclusions contained in this document are based on FCC database records1. Frequently, wind turbines located on land parcels near RF facilities can cause more than one mode of RF impact, and may require an iterative procedure to minimize adverse effects. This procedure is necessary in order to ensure that disruption of RF facilities either does not occur or, in the alternative, that mitigation procedures will be effective. The purpose of this study is to facilitate the siting of turbines to avoid such unacceptable impact. The Great Pathfinder Wind project as currently planned involves the construction of up to 74 wind turbines just southeast of the city of Stratford, in northern Boone County and southwestern Hamilton County, Iowa.

  • How Nexrad Weather Radar Data Can Benefit the Wind Energy Industry
    HOW NEXRAD WEATHER RADAR DATA CAN BENEFIT THE WIND ENERGY INDUSTRY Richard. J. Vogt* and Timothy D. Crum NEXRAD Radar Operations Center, Norman, Oklahoma Edward J. Ciardi and Ronald G. Guenther SERCO, NEXRAD Radar Operations Center, Norman, Oklahoma William H. Greenwood Cooperative Institute for Mesoscale Meteorological Studies, University of Oklahoma Norman, Oklahoma 1. INTRODUCTION The Nation’s federal weather radar operators (Departments of Commerce, Defense, and Transportation) and the wind energy industry share common goals of enhancing the Nation’s economy and quality of life for its citizens. Data from the Nation’s network of remote sensors (e.g., weather radars, wind profilers); in situ sensors (e.g., surface and upper air observations); and numerical weather prediction models are readily available to wind energy industry and their private sector weather service suppliers to support their weather-sensitive operations. Federal weather radars include the Next Generation Weather Radar (NEXRAD (also known as Weather Surveillance Radar-1988, Doppler (WSR-88D)) and the Federal Aviation Administration’s (FAA’s) Terminal Doppler Weather Radar (TDWR). Federal weather radar data -- both real time and archived – are a rich source of information that can be used by the wind energy industry to improve efficiency of power generation and siting decisions. Real-time weather radar data can improve short-term (0 to ~2 hour) forecasts of wind energy production and resource protection decisions. Radar data are used to initialize numerical weather prediction models operated by the National Oceanic and Atmospheric Administration’s National Weather Service (NOAA’s NWS) and wind energy industry private sector wind forecasting services.

  • NEXRAD Radar Mosaic with Winter Overlay
    Weather Help - NEXRAD Radar Maps NEXRAD Radar Mosaic with winter overlay NEXRAD Radar Mosaic: 16 levels for three distinct precipitation types, rain; mixed precipitation and snow are depicted using 3 distinct color palettes. Legend associated colors with precipitation intensity. Severe Thunderstorm/Tornado Watch Areas: Yellow box indicates a Severe Thunderstorm Watch area. A Red box indicates a Tornado Watch area. Watch areas represent areas where the conditions are favorable for the development of severe thunderstorms or tornadoes. Airport Locations: Selected airport locations are indicated on the background map using the 4 letter ICAO identifier in white. NEXRAD radar composite reflectivity measures the intensity of radar echo returns from precipitation particles. The larger and more dense the particle, the greater the value the return will be. Reflectivity is generally associated with precipitation rate, such that the greater the reflectivity, the heavier the precipitation rate. It is also generally assumed that higher reflectivity values (above 40 DBZ) are associated with convective precipitation. Lightning and hail are more likely to be present with higher reflectivity values. Composite reflectivity represents the full volume of scan angles from the radar. The Jeppesen Composite Reflectivity maps are national and regional mosaics, which combine the information from individual radar sites. Winter Radar Mosaic overlay depicts composite reflectivity in unique color schemes so that users can easily differentiate between rain, mixed precipitation and snow during winter months. A complex computer algorithm uses NEXRAD composite reflectivity and identifies areas where snow, freezing rain and mixed precipitation are falling. Using distinct colors, users can identify various precipitation regimes. Rain is depicted using 16 colors ranging from dark green (light rain) to yellow (moderate rain) to dark red (heavy rain).

  • TO: All Interested Parties FROM: Jessica Schultz, Radar Focal Point
    TO: All Interested Parties FROM: Jessica Schultz, Radar Focal Point, National Weather Service (NWS) SUBJECT: Lowering the Minimum Scan Angle of the KMBX Weather Surveillance Radar - Model 1988 Doppler (WSR-88D) serving Minot, ND, area DATE: February 4, 2019 In accordance with provisions of the National Environmental Policy Act of 1969, the National Weather Service (NWS) prepared a Draft Environmental Assessment (EA) analyzing the potential environmental effects of lowering the minimum scan angle of the KMBX WSR-88D serving the Minot, ND, area. The Draft Environmental Assessment is available for public review and comment. The Draft EA may be obtained at: https://www.roc.noaa.gov/WSR88D/SafetyandEnv/EAReports.aspx The KMBX WSR-88D is an existing radar facility located at an agricultural field in McHenry County about 24 miles east of Minot, ND. The KMBX WSR-88D was commissioned in October 1994 and is one of 159 WSR-88Ds in the nationwide network. The KMBX WSR-88D antenna transmits a narrow focused main beam with a width of 1 degree. In normal operation, the radar antenna rotates horizontally to cover all directions (i.e. azimuths). The radar antenna also varies the scan angle at which it points with respect to the horizon. Currently, the WSR-88D operates at a minimum of scan angle of +0.5 degrees (deg) above the horizon. NWS proposes to reduce the minimum scan angle of the KMBX WSR-88D from the current minimum of +0.5 deg to +0.3 deg (i.e. 0.2 deg lower than existing) to provide enhanced coverage of the lower portions of the atmosphere.
