The Department of Commerce, specifically the National Oceanic and Atmospheric Administration (NOAA), is seeking sources for an Indefinite Delivery Indefinite Quantity (IDIQ) contract for isotope analysis of atmospheric trace gases in Boulder, Colorado. The procurement aims to identify vendors capable of providing comprehensive analysis of isotopic ratios and radiocarbon from atmospheric air samples, including stable isotopes of Carbon Dioxide (CO2) and Methane (CH4), with a focus on measurement precision and timely data delivery. This analysis is crucial for understanding greenhouse gas concentrations and isotopic ratios, which play a significant role in climate monitoring and research. Interested parties must respond by December 12, 2025, at 10:00 AM Mountain Standard Time, and can contact Anthony Eubanks at anthony.eubanks@noaa.gov or Remo Dela Cruz at remo.dela-cruz@noaa.gov for further information.

The National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Laboratory (GML) Global Greenhouse Gas Reference Network (GGGRN) requires comprehensive analysis of isotopic ratios and radiocarbon from atmospheric air samples and reference standards. The vendor will provide quality-controlled isotope analysis of multiple atmospheric trace gases, including stable isotopes of Carbon Dioxide (CO2), Radiocarbon (14C) of Carbon Dioxide (CO2), Radiocarbon (14C) of Methane (CH4), Stable isotopes of Methane (CH4), and Triple oxygen isotope ratios of carbon dioxide (∆17O). Key requirements include specific measurement precision, demonstrated long-term performance, and timely data delivery in NOAA GML compatible formats. The vendor is also responsible for sample transportation beyond a five-mile radius of the GML facility in Boulder, CO. Additionally, the scope includes scientific interpretation of atmospheric greenhouse gas concentration and isotopic ratio measurements for CO2, CH4, and N2O, involving time series analysis, north-south gradient analysis, and estimation of emissions and removals. Performance will be assessed based on the accuracy and reproducibility of measurements and the quality and timeliness of scientific interpretations and data submissions.
