Federal Grant Award Summary San Jose State University Research Foundation received a $374,521 Project Grant from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) awarded July 1, 2026, with completion scheduled for June 30, 2029. The award supports controlled laboratory research on aerosol-mixed phase cloud interactions using Michigan Tech University's PI Cloud Chamber facility. The project will generate multiple steady-state mixed-phase clouds—clouds containing both liquid and ice simultaneously—under varying conditions to investigate how these clouds respond to different concentrations of cloud condensation nuclei (CCN) and ice nucleating particles (INP), as well as different temperature gradients and water vapor flux forcing. The research deliverables will advance understanding of mixed-phase cloud microphysics by determining how ice and supercooled liquid water particle size distributions respond to aerosol perturbations, and how the ice integral radius values required to fully glaciate mixed-phase clouds vary under different thermodynamic conditions. These findings are intended to improve precipitation forecasts and provide critical data for aircraft icing studies. The award includes planned subawards to partner institutions and reflects NSF's commitment to strengthening fundamental knowledge of integrated Earth system processes through atmospheric science research.
