The Pacific Coastal Fog Project
Coastal marine fog is an important meteorological phenomenon for California. A cloud—either stratus or stratocumulus—is called “fog” when it is low or touching the ground. Marine fog forms as a result of complex interactions between ocean evaporation, aerosols, atmospheric pressure, vertical air layering, onshore-offshore temperature gradients, and coastal mountain topography. The marine cloud...
Moving from Awareness to Action: Informing Climate Change Vulnerability Assessments and Adaptation Planning for Idaho and Montana National Forests
The rugged landscapes of northern Idaho and western Montana support biodiverse ecosystems, and provide a variety of natural resources and services for human communities. However, the benefits provided by these ecosystems may be at risk as changing climate magnifies existing stressors and allows new stressors to emerge. Preparation for and response to these potential changes can be most...
Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings
In June and July 2021, the Colorado River Basin Actionable and Strategic Integrated Science and Technology (ASIST) pilot team held a series of 12 Science and Technology Collaboration meetings with U.S. Geological Survey science staff to discuss complex integrated science challenges and solutions related to drought in the Colorado River Basin. These meetings were structured to explore...
A snapshot of stakeholder science needs related to drought in the Colorado River Basin
Stakeholder science needs were determined by reviewing more than 200 recently published literature items and web pages from Colorado River Basin (CRB) stakeholders. These stakeholder communications were used to characterize over 400 stakeholder science needs by reviewing their priorities, strategies, issues, missions, and concerns related to drought in the CRB. Members of the CRB...

Liquid water content of summertime coastal California fog events, San Mateo County
Measurements of liquid water content (LWC) of coastal fog events were collected using specialized fog water collection units during the hot dry summer season (July to September) and continued through the winter. These data were assembled to explore the potential of fog water collection as a water resource for Midpeninsula Regional Open Space District public lands in San Mateo County...

Integrating climate change considerations into natural resource planning—An implementation guide
Executive SummaryClimate change vulnerability assessments and associated adaptation strategies and actions connect existing climate science with possible effects on natural resources and highlight potential responses. However, these assessments, which are commonly generated for large regional areas, suggest management options in general terms without guidance for choosing among...

Marine fog inputs appear to increase methylmercury bioaccumulation in a coastal terrestrial food web
Coastal marine atmospheric fog has recently been implicated as a potential source of ocean-derived monomethylmercury (MMHg) to coastal terrestrial ecosystems through the process of sea-to-land advection of foggy air masses followed by wet deposition. This study examined whether pumas (Puma concolor) in coastal central California, USA, and their associated food web, have elevated...

Hydrologic resilience from summertime fog and recharge: A case study for coho salmon recovery planning
Fog and low cloud cover (FLCC) and late summer recharge increase stream baseflow and decrease stream temperature during arid Mediterranean climate summers, which benefits salmon especially under climate warming conditions. The potential to discharge cool water to streams during the late summer (hydrologic capacity; HC) furnished by FLCC and recharge were mapped for the 299 subwatersheds...

Fog water collection effectiveness: Mesh intercomparisons
To explore fog water harvesting potential in California, we conducted long-term measurements involving three types of mesh using standard fog collectors (SFC). Volumetric fog water measurements from SFCs and wind data were collected and recorded in 15-minute intervals over three summertime fog seasons (2014–2016) at four California sites. SFCs were deployed with: standard 1.00 m2 double...

@KarlTheFog has been mapped!
Within the world of mapping, clouds are a pesky interference to be removed from satellite remote sensed imagery. However, to many of us, that is a waste of pixels. Cloud maps are becoming increasingly valuable in the quest to understand land cover change and surface processes. In coastal California, the dynamic summertime interactions between air masses, the ocean, and topography result...

GOES-derived fog and low cloud indices for coastal north and central California ecological analyses
Fog and low cloud cover (FLCC) changes the water, energy, and nutrient flux of coastal ecosystems. Easy-to-use FLCC data are needed to quantify the impacts of FLC on ecosystem dynamics during hot, dry Mediterranean climate summers. FLCC indices were generated from 26,000 hourly night and day FLCC maps derived from Geostationary Environmental Operational Satellite (GOES) data for June...

Coastal fog, climate change, and the environment
Coastal marine fog, a characteristic feature of climates generated at the eastern boundaries of ocean basins worldwide, evokes different feelings in those who experience it (see Figure 1). Authors and poets use fog to represent mystery, bleakness, and confusion. Film directors seek out fog to shroud scenes in eerie gloominess. Tourists visiting beaches bemoan the cool and damp conditions...
