About this opportunity
The National Oceanic and Atmospheric Administration's Acquisition and Grants Office, Eastern Acquisition Division–Kansas City intends to negotiate and award a purchase order on a sole source basis with Vaisala for replacement radiosondes (part number RS41-SGP), with a response deadline of July 25, 2026.
The sole source determination rests on Vaisala's exclusive manufacturer status for the Line Replaceable Units integrated into the Automatic Radiosonde Observing Systems since the NWS adopted the platform. No other manufacturer produces these components. The radiosondes will be delivered to the National Logistics Support Center in Grandview, Missouri, and support the AROS system's collection of critical atmospheric variables—temperature, humidity, barometric pressure, and winds at multiple altitudes—essential for weather forecasting and modeling.
Under FAR 6.103-1, NOAA has determined a competitive procurement unnecessary; however, firms believing they can fully meet requirements may submit substantiating documentation or request additional information to the contract specialist within 15 days of this notice's publication. The government will evaluate such submissions solely to determine whether to conduct a competitive procurement. The government retains sole discretion to reject competitive procurement based on responses. Oral communications are not acceptable. This pre-solicitation notice is not a request for competitive proposals and no solicitation package is currently available.

The National Oceanic and Atmospheric Administration’s (NOAA) Acquisition and Grants Office, Eastern Acquisition Division-Kansas City intends to negotiate and award a purchase order, on a sole source basis, under authority of RFO FAR 6.103-1, with Vaisala for replacement radiosondes (p/n RS41-SGP) to be delivered to the National Logistics Support Center in Grandview, MO.

The Vaisala Line Replaceable Units (LRUs) are integrated components since the inception of Automatic Radiosonde Observing Systems (AROS) into the National Weather Service (NWS). Vaisala is the only manufacturer of these Line Replaceable Units. This order will help the AROS system maintain accurate barometric pressure readings for radiosonde weather balloon launches. Radiosondes are instruments on weather balloons that collect critical atmospheric variables, including temperature, humidity, pressure, and winds at various altitudes, which are essential for weather forecasts and weather models.
