"NSF 25-530 Collaborations in Artificial Intelligence and Geosciences (CAIG) for AI Methods Advancing Climate, Weather, Ocean, Atmospheric and Earth System Science" is currently closed and not accepting applications.
CAIG is NSF's dedicated vehicle for pairing AI method development with geoscience, jointly run by the Geosciences, Computer and Information Science and Engineering, and Mathematical and Physical Sciences directorates.
It targets innovative artificial intelligence methods that increase scientific understanding of the Earth system, addressing research questions in atmospheric, ocean and polar sciences while also advancing the AI techniques themselves.
That two-sided requirement is the crux of the programme and the most common reason proposals fail: a project that applies an off-the-shelf model to a geoscience dataset does not advance AI, and a project that develops a novel architecture without a real Earth-system question does not advance geoscience. Reviewers under this solicitation look for both. The team structure is prescribed rather than suggested.
Projects must feature interdisciplinary teams of 2 to 3 lead collaborating Senior/Key Personnel plus associated students, postdoctoral researchers and research software engineers, with meaningful partnership between geoscience and AI experts.
The explicit inclusion of research software engineers as fundable personnel is notable and worth using - it is a recognition that AI-geoscience work needs sustained software capacity, which many proposals under-budget. A limit applies: an individual may serve as Senior/Key Personnel on a maximum of two proposals per competition.
Award scale is moderate - NSF anticipates 5 to 9 awards totalling 6,000,000 to 10,000,000 dollars per competition, over up to 3 years - so this suits focused collaborations rather than centre-scale efforts. Eligibility covers US institutions of higher education, nonprofit research organizations, tribal nations, and federal agencies and FFRDCs.
Documented full proposal deadlines were 2 April 2025 and 4 February 2026; the competition recurs, so the solicitation page should be checked for the next cycle.

Projects must feature interdisciplinary teams of 2 to 3 lead collaborating Senior/Key Personnel, together with associated students, postdoctoral researchers and research software engineers, and must demonstrate a meaningful partnership between geoscience and AI expertise rather than a one-sided application of existing methods. An individual researcher may serve as Senior/Key Personnel on a maximum of two proposals per competition. Scope requires both sides of the collaboration to advance: innovative artificial intelligence methods that increase scientific understanding of the Earth system, addressing geoscience research questions in atmospheric, ocean and polar sciences while also advancing AI techniques. NSF anticipates 5 to 9 awards per competition with total funding of 6,000,000 to 10,000,000 US dollars per competition and a maximum project duration of 3 years; per-award amounts are not published. The programme is a partnership across the NSF Directorates for Geosciences (GEO), Computer and Information Science and Engineering (CISE), and Mathematical and Physical Sciences (MPS). Documented full proposal deadlines under solicitation NSF 25-530 were 2 April 2025 and 4 February 2026; the 4 February 2026 deadline has passed. Note that an earlier version, NSF 24-518, is archived.

The current listing shows NSF anticipates 5 to 9 awards per competition with total funding of 6,000,000 to 10,000,000 US dollars per competition, and a project duration of up to 3 years. No per-award minimum or maximum is stated in the solicitation. amount_min of 667,000 and amount_max of 2,000,000 US dollars are INFERRED by dividing the published total funding range by the published award count range (10,000,000 divided by 9 at the low end of generosity, 10,000,000 divided by 5 at the high end), and are not NSF figures. Actual awards will vary with team size and scope, and NSF reserves the right to fund at other levels. The authoritative budget guidance is in the solicitation's Award Information section, which must be read before a budget is built. Awards are standard grants or continuing grants subject to the availability of funds. Verify award ceilings, matching requirements, and allowable costs in the official notice.
The published deadline was February 4, 2026, which has passed. Check the official notice for any future application windows before investing time in a proposal.

The NSF Computer and Information Science and Engineering: Future Computing Research (Future CoRe) program (NSF 25-543) supports foundational computing research and education with a strong emphasis on AI and machine learning. The program funds research that advances the foundations of computing including AI/ML theory, algorithms, systems, and applications. Future CoRe supports small to medium-sized research projects that can have significant impact on computing foundations. The program has target dates of February 5, 2026 and September 10, 2026 for proposal submissions (note: these are target dates, not deadlines, meaning proposals may be submitted at any time but will be reviewed in batches around these dates). Investigators may not serve as PI, co-PI, or Senior/Key Personnel on more than two proposals submitted within any consecutive 12-month period across all Future CoRe programs. This is one of NSF's primary mechanisms for funding fundamental AI and machine learning research at U.S. academic institutions, covering areas such as machine learning theory, natural language processing, computer vision, robotics foundations, and human-AI interaction.
The ONR Long Range Broad Agency Announcement (N00014-25-S-B001) is the Office of Naval Research's primary mechanism for soliciting research proposals across all naval science and technology priority areas. The BAA accepts proposals on a rolling basis through September 30, 2026 and covers ONR's full spectrum of research interests with particular emphasis on AI-related topics including autonomous maritime systems, human-machine teaming, machine learning for sensor fusion, cooperative autonomous swarm technology, undersea autonomy, and AI-enabled decision superiority. Proposals can be funded through multiple mechanisms including individual investigator grants, the Young Investigator Program (~$510K over 3 years for early-career faculty), and Multidisciplinary University Research Initiative (MURI) awards ($1.5M/year for 3-5 years for research teams). ONR recommends contacting relevant program officers before submitting to discuss alignment with current research priorities. The BAA supports basic research (6.1), applied research (6.2), and advanced technology development (6.3) across the full range of naval-relevant science and engineering disciplines.

DOE anticipates 200 to 350 new awards ranging from $5,000 to $5 million each, with project periods from six months to five years. The FOA opened September 30, 2025 and accepts applications on a rolling basis through the end of FY 2026.
NSF 26-516 folds Atmospheric and Geospace Sciences, Earth Sciences and Ocean Sciences into a single GEO Core solicitation: $110 million, 200 to 350 awards, proposals accepted anytime. Geosciences piloted no-deadline review nine years ago and knows what it does to submission volume. Here is the per-award math, the ship-time and permitting traps, and the two-year data-archive clock that now governs every award.
Read articleNSF 26-523 folds 12 core physics programs and three cross-cutting ones into a single solicitation with $180 million and roughly 300 awards. Proposals are accepted anytime, but AMO-Experiment and Gravitational Physics still target November 25 and QIS targets December 8. Cost sharing is prohibited, indirect cost rates are now a tiebreaker, and NSF reserves the right to phase out long-duration efforts after comparative review.
