We evaluated different methods to obtain the ice nucleating particle (INP) concentration from ambient filters using GRAINS (GRAnada Ice Nuclei Spectrometer), the INP spectrometer at the Andalusian ObseRvatory of the Atmosphere (AGORA). We first characterized GRAINS and compared it to other INP devices. Then, we sampled polycarbonate and quartz filters for three months and tested three different particle extraction methods, finding general good agreement but that the INP concentration is systematically higher when using quartz filters.

We ask how the amount of aerosol particles shapes cloud structure. Using computer simulations of a laboratory cloud chamber, we varied aerosol levels and tracked droplet growth. When aerosols are few, cloud water increases with height; when many, it becomes almost uniform because vapor is used up near the bottom. These findings clarify when upward motions matter and guide chamber design and better cloud treatment in weather and climate models.

We propose a multiple-charging correction algorithm for a broad-supersaturation scanning cloud condensation nuclei (BS2-CCN) system which can obtain high time-resolution aerosol hygroscopicity and CCN activity. The correction algorithm aims at deriving the activation fraction's true value for each particle size. The meaningful differences between corrected and original κ values (single hygroscopicity parameter) emphasize the correction algorithm's importance for ambient aerosol measurement.

Short summary
A broad supersaturation scanning CCN (BS2-CCN) system, in which particles are exposed to a range of supersaturation simultaneously, can measure a broad range of CCN activity distribution with a high time resolution. We describe how the BS2-CCN system can be effectively calibrated and which factors can affect the calibration curve. Intercomparison experiments between typical DMA-CCN and BS2-CCN measurements to evaluate the BS2-CCN system showed high correlation and good agreement.

Short summary
Aerosols are tiny particles in the air, and some of them help form cloud droplets (called cloud condensation nuclei). Most ship measurements focus on only one ocean. To compare aerosols over several oceans, we measured them during a transit voyage of a research ship using the same method. The results show that properties of these particles cannot be represented by a single marine condition. Moreover, they changed widely, depending on where the air came from and the pathway it traveled.
