Vaisala, Inc model number RS41 radiosondes

Waiver Rationale Summary

The current multi-procurement waiver for contract 1305M222DNWWG0002 expired in August 2024. With no changes in mission or need since contract award, the new multi-procurement waiver is being requested for the remainder of the contract period of performance, until September 30, 2031. The Government anticipates ordering 17,641 radiosondes per year, at an estimated annual cost $2.2M. Although only foreign-manufactured items were offered and selected for this procurement, NWS program management continues regular market research of radiosonde manufacturers to stay well informed of current and future products and technology enhancements. If compatible domestic radiosondes sources are identified, NWS will consider these sources and assess capabilities to determine whether any emergent manufacturers can meet mission requirements. As of the date of this waiver, none exist. Market research has been continuous since contract award. Efforts to identify domestic sources have been conducted by multiple agencies with no sources identified. It is unlikely that market conditions will change during the duration of the waiver due to the nature of a niche community of weather sensor manufacturers despite government efforts to identify responsible and capable sources.
