The National Oceanic and Atmospheric Administration (NOAA) is seeking sources for a Gill R3A-100 sonic anemometer to support precise wind measurements for marine research. This 3-axis ultrasonic anemometer must meet specific technical requirements, including a 100Hz output rate, 0-45 m/s wind speed range, and marine environmental durability. Delivery of the instrument is required by August 30, 2026. The work will be performed to support NOAA’s Physical Sciences Laboratory, with no specific performance location mentioned. No budget information is provided in this sources sought notice.
