The Climate Program Office (CPO) plays a critical role in advancing science and informing decisions for climate adaptation, resilience, and mitigation as part of NOAA and the U.S. Global Change Research Program. CPO research/science programs and activities meet urgent climate challenges, and incubate innovative advancements in Earth system and social sciences; support world-class assessment reports, including the National Climate Assessment; enhance and expand NOAA’s capabilities for integrated information systems for drought, heat and floods to deliver timely science-based information that can reduce the impacts and costs of these climate-driven challenges; educate and grow the next generation of experts in support of NOAA’s climate mission. Through these new investments, CPO expands previous efforts focused on climate risks to address a suite of urgent climate-driven societal challenges faced by our Nation — including water availability and quality, marine and freshwater ecosystems, coastal changes and inundation, drought and extreme heat and related cascading hazards like wildfire, and air quality, and climate mitigation (more information about CPO Societal Challenges and Risks framework can be found here.

In FY25, AC4 solicits proposals focused on the following priorities:

  • Prototypes of urban GHG and air quality monitoring to evaluate the impact of climate action plans and other mitigation actions, including streamlining and coordination of ongoing efforts
  • Quantifying sources and sinks of urban trace gasses and aerosols, especially Ammonia (NH3), methane (CH4) and Secondary Organic Aerosols (SOA)
  • Improved understanding of compounding effects of heat, fire and other hazards on air quality and GHG concentrations
  • Data analysis and modeling of urban measurements associated with NOAA field campaigns, e.g. AEROMMA
  • Understanding interactions between boundary layer processes, and trace gas and aerosol chemistry and transport
  • Measurements from various observing platforms and modeling that help validate and show the utility of satellite data in urban areas
  • Urban monitoring in collaboration with local communities at increased risk of health impacts due to poor air quality, especially those identified in EPA’s EJScreen tool
  • Understanding urban vegetation’s role in urban air composition, including its changes with changing climate
  • Urban-relevant measurements that are aligned with NOAA’s AiRMAPS field campaign

Application Deadline: Letters of intent (LOIs) due by 11:59 pm Eastern Time on September 18, 2024; full applications due by 11:59 pm Eastern Time on December 9, 2024.
