By supporting this project, NASA would obtain airborne INP measurement capabilities that would support model validation and airborne science program field campaigns, similar to those discussed in the ROSES-2018 solicitation. Suitable platforms include the DC-8, P-3, C-20A and G-V. Relevant campaigns include any that include a focus on aerosol-cloud interactions, similar to FIREChem, NAAMES, ORACLES, ARISE II, CAMP2Ex and potentially those funded by the currently open EVS-3 solicitation.
Domestically, agencies with an interest in measuring INP from aircraft include the Department of Energy ASR/ARM, NOAA CSD, and NSF/NCAR atmospheric chemistry programs. Foreign government organizations include the UK MetOffice (BAe-146) and German DLR (G-V). Handix Scientific also has a close connection with investigators internationally because its owner is an atmospheric research instrument distributor for several US-based companies, and we anticipate interest from this emerging community.
