NASA/NSSC has a requirement for 90 radiosondes and antenna preamplifiers for Natal and Hanoi. NASA/NSSC intends to issue a sole source contract to VAISALA INC, located at 194 S Taylor Ave, Louisville, Colorado 80027, as they are determined to be the sole provider of these items. The purpose of this contract is to support long-term SHADOZ ozonesonde measurement stations at Wallops Island, Natal, Brazil, and Hanoi, Vietnam. These stations are essential for maintaining multi-decadal balloon-borne ozone profile records for satellite validation, ozone and pollution trends, and climate studies.

The contract includes the delivery of 90 radiosondes and antenna preamplifiers specifically designed for use at the SHADOZ stations in Natal and Hanoi. The requirement is part of a larger order that includes:

- 100 radiosondes
- 120 ozone interface kits of different models
- 146 ozone interface kits
- An additional 55 kits of different models

These products must ensure consistency with existing SHADOZ records and compatibility with current ground data collection systems at the specified locations.

Period of Performance
The expected delivery date for this order is November 30, 2026.

Place of Performance
The work will be performed at Wallops Island, Natal in Brazil, and Hanoi in Vietnam.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a confirmed incumbent based on the closely related prior contract 80NSSC25PB840 awarded to Vaisala for “90 VAISALA RADIOSONDES AND ANTENNA PREAMPLIFIER FOR NATAL AND HANOI” (value $55,728; 09/03/25–09/30/25). The current requirement is for the same type of equipment (radiosondes and antenna preamplifiers) and the same locations (Natal and Hanoi), suggesting the new procurement may be a continuation or follow-on delivery to support ongoing SHADOZ station operations.
