Fog & Precipitation
Impacting climate models, visibility, and water supplies
Fog and precipitation have important implications for environmental research, everyday operational safety, and water supplies. Data collected from Droplet’s fog and precipitation instruments provide detailed characterizations that help you understand formation and microphysics, critical information for forecasting and nowcasting models. The Droplet portfolio of fog and precipitation instruments enable:
Continuous sampling of droplet-laden ambient air to produce size distributions from 2 µm to 50 µm
Imaging of individual precipitation particles, recording information on shadow image, fall velocity, and particle spacing
Explore the research applications
Visibility studies
Better understanding fog-induced low visibility and improving parameterization of fog microphysics.

The main driver of this warming is an increase in the global concentration of carbon dioxide; however, various other climate forcers and feedback processes are amplifying the magnitude of warming in the Arctic (e.g., Serreze & Barry, 2011)."
