The National Science Foundation (NSF) is offering Atmospheric and Geospace Sciences Postdoctoral Research Fellowships aimed at supporting early career investigators in conducting independent research within the Atmospheric and Geospace Sciences disciplines. Eligible applicants must be U.S. citizens or permanent residents, either current graduate students or individuals who have recently obtained a PhD, and must propose research that aligns with the NSF's focus areas, including Atmospheric Chemistry, Climate Dynamics, and Space Weather Research. The fellowship provides funding for up to 24 months, with a total estimated program funding of $2 million, and encourages proposals that enhance diversity and inclusion within the geosciences. Interested candidates can submit proposals at any time, and for further assistance, they may contact NSF grants.gov support at grantsgovsupport@nsf.gov.
