The Simons Foundation’s Mathematics and Physical Sciences (MPS) division invites applications for a new Solar Radiation Management program (SRM). The foundation strongly encourages applications from scientists in the global south and from investigators who may not have worked in SRM but have expertise that could bring new perspectives and skills to this field.

The Simons Foundation is launching an international collaborative research program designed to fill fundamental scientific knowledge gaps relevant to Solar Radiation Management. SRM is an emerging collection of approaches, including stratospheric aerosol injection (SAI), marine cloud brightening (MCB), and cirrus cloud thinning (CCT), designed to modify the Earth’s radiative balance and cool the planet.

The program is anticipated to award $10M total per year over a five-year period. Proposal budgets should not exceed $500,000 per year, including indirect costs (limited to 20 percent modified total direct costs), for a period of three years. Allowable indirect costs to the primary institution for subcontracts are not included in the $500,000 budget threshold (see grant policies). Up to 20 awards will be funded although some of the original $10M may be held in reserve to award during a potential two-year renewal period after the initial three year award.

Application Deadline: LOI due at 12 p.m. (noon) EDT
