The NASA/NSSC has a requirement for 415 1220-gram and 55 1500-gram weather balloons for the SHADOZ Network. The SHADOZ long-term ozonesonde measurement network needs to continue their multi-decadal balloon borne ozone profile records for satellite validation, ozone and pollution trends, and climate studies. The weather balloons are required to ensure consistency with the existing SHADOZ records. The operators at SHADOZ stations shall prepare, launch, and collect the data from instrumentation carried by the weather balloons, and send the data to NASA/GSFC in Greenbelt, MD. • The weather balloons will be shipped to four different locations that assist with SHADOZ logistics. • The work will be performed at SHADOZ stations in the tropics. • The order represents an approximately one-year supply of weather balloons to be delivered by 30 September 2026.
