Kenneth Maclean air sampling flights

This five year forecast from the Department of Commerce Office of Oceanic and Atmospheric Research seeks aircraft services to conduct research quality measurements of atmospheric trace gases and meteorological data. The project focuses on sampling species such as carbon dioxide, methane, carbon monoxide, hydrogen, nitrous oxide, and sulfur hexafluoride, along with pressure, temperature, and humidity. Flights will operate at various altitudes up to approximately 25,000 feet to support the Global Greenhouse Gas Reference Network sampling site located southeast of Portsmouth, New Hampshire. The primary objective of these flights is to enhance the understanding of emissions locations, source strength, and seasonality to advance air quality and climate science studies in alignment with the NOAA mission. The requirement is categorized under NAICS code 561990 and is managed by the Office of Oceanic and Atmospheric Research.
