About this file
This Statement of Work (SOW) details a contract for Vaisala radiosondes and equipment for two long-term ozonesonde measurement stations located in Natal, Brazil, and Hanoi, Vietnam. The procurement includes 90 Vaisala radiosondes, ozone interface kits, and a replacement antenna preamplifier for the ground system in Natal, with the primary purpose of continuing multi-decadal balloon-borne ozone profile records for satellite validation, ozone and pollution trend analysis, and climate studies.
The work will be performed at the SHADOZ (Southern Hemisphere Additional Ozonesondes) stations, with operators preparing, launching, and collecting radiosonde data to be sent to NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. The period of performance spans approximately one year, from August 2025 to July 2026, ensuring continuity of existing measurement records and maintaining compatibility with current ground data collection systems at both locations.
