Notice Number: 145022-26-0006JRW Notice Type: Sources Sought Title: Vaisala Ultrasonic Wind Sensors Response Date: May 14, 2026 This is a SOURCES SOUGHT and is not a pre-solicitation announcement. The purpose of this Market Research and Sources Sought Notice is to gain knowledge of potential qualified businesses, which could include Small Business, HUBZone, 8(a), Service Disabled Veteran Owned, Women Owned Small Business firms and even Large Businesses offering domestically manufactured products that meet the required specifications. Responses to this Sources Sought will be used by the Government in making appropriate acquisition decisions. The National Oceanic and Atmospheric Administration (NOAA) Oceanic and Atmospheric Research (OAR), Special Operation and Research Division mission is to collect meteorological data on and near the Idaho National Laboratory (INL). Special Operation and Research Division requires nineteen (19) Vaisala WMT700 series heated 2-D sonic anemometers, with separate caging for bird protection and adapters for pole mounting, to measure horizontal wind speed, direction, and variability, to determine the flow of the atmosphere and atmospheric stability for emergency response plume modeling. INTENDED USE/PURPOSE: This is the only known instrument that can meet the Government's needs, and this notice's intent is to identify any other products that meet the full requirements listed below. These data collected are required to produce daily weather forecasts and spot forecasts for specific times and locations, conduct daily weather surveillance, generate severe and extreme weather warnings and advisories, provide long-term data records, collect environmental compliance data, and perform emergency response activities. SPECIAL REQUIREMENTS/ESSENTIAL SALIENT FEATURES: Wind speed measurement performance Observation range: 0 … 65 m/s (145 mph) Starting threshold: 0.01 m/s (0.0223 mph) Resolution: 0.01 m/s (0.0223 mph) Response time: 250 ms Accuracy: 0 … 75 m/s (168 mph): ±0.1 m/s (0.2 mph) or 2 % of reading, whichever is greater 75 … 90 m/s (201 mph): ±5 % of reading Wind direction measurement performance Observation range: 0 … 360° Starting threshold: 0.1 m/s (0.2 mph) Resolution: 0.01° Response time: 250 ms Accuracy: ±2° Powering specifications Operating voltage: 9 … 36 V DC (absolute max. 40 V DC) Heating voltage: 24 … 36 V DC (absolute max. 40 V DC) Heating power supply requirement: Must have heated transducers, arms, and body, average 250 W Peak 350 W at 24 V DC Messaging specifications Readout update interval: 4 Hz (default) and 8 Hz (optional) Units available: m/s, knots, mph, km/h, V, mA, Hz Operating mode: Automatic message or poll mode Virtual temperature: Celsius degrees Mechanical specifications Dimensions: (H × W × Ø 1)) 348 × 250 × 285 mm, (13.70 × 9.84 × 11.22 in) Weight: 1.8 kg (4.0 lb) Materials: Body and arms, mounting kit Stainless steel …
