CCN counter (CCNc)

The scope of this procurement is:

Interactions between atmospheric aerosol particles and clouds are among the key uncertainties in climate predictions. This hampers our ability to design successful policies for meeting the targets of the Paris agreement. To mitigate this problem, accurate observational data on the potential of various atmospheric aerosol populations to influence the properties of clouds is needed. With this procurement, we seek to complement our suite of instrumentation for simultaneous observations of cloud and aerosol microphysics with two CCN counters.
