Replacement Radiosondes for the National Logistics Support Center in Grandview, MO.

The National Oceanic and Atmospheric Administration (NOAA) is seeking to negotiate and award a purchase order for replacement radiosondes to be delivered to the National Logistics Support Center in Grandview, MO. The radiosondes, specifically the RS41-SGP model, are used to collect critical atmospheric variables, including temperature, humidity, pressure, and winds at various altitudes, which are essential for weather forecasts and weather models. The sole source determination is based on NOAA's Sole Source Justification, as Vaisala is the only manufacturer of the RS41-SGP Radiosonde. • The RS41-SGP model is required for the Barrow, AK site due to its critical need for surface pressure data and collaboration with the Department of Energy. • The radiosondes will be used for weather balloons to collect data, which is essential for weather forecasts and models. • The lack of radiosondes would affect the weather prediction data in the region and impede the NWS mission of protecting life and property.
