| Description: | The Bernard Field Station (BFS), an 86-acre academic resource of the Claremont University Consortium, is situated within the campus of The Claremont Colleges ... The Bernard Field Station (BFS), an 86-acre academic resource of the Claremont University Consortium, is situated within the campus of The Claremont Colleges in Claremont, CA. Its principal habitats comprise coastal sage scrub, Riversidian alluvial fan scrub, live oak forest, and grassland. The eddy covariance tower is located in the 'neck' of the field station, home to a protected area of Coastal Sage Scrub, dominated by Artemisia californica. BFS is within walking distance of Harvey Mudd College, serving as an invaluable outdoor laboratory resource for the students. With extensive flora and fauna, including over 170 species of birds, 27 species of mammals, and more than 700 species of insects, it embodies a significant ecological haven in the region that is otherwise Southern California suburbs.

The key analytical objectives of the Bernard Field Station site include the measurements of momentum, sensible heat, water vapour, latent heat, and CO2 exchange between the coastal sage scrub and the atmosphere. Among the additional research topics includes: 1) investigation of the relationships of energy and mass exchanges between the atmosphere and the Coastal sage scrub as the region warms and precipitation patterns change; 2) speciatied Volatile Organic Compound (VOC) measurements performed directly from plant species that makeup sage scrub community to link reactive carbon fluxes with ecosystem respiration; 3) plant physiology, particularly involving the dominant Artemisia californica within the coastal sage scrub; 4) studying long-term impact of climate change on this unique ecosystem; 5) exploring interactive carbon chemistry to understand its implications for the ecosystem and beyond.

PhenoCam Images and Derived Time Series Data
PhenoCams are high-resolution digital cameras that take repeated images of studied ecosystems and provide quantitative information about the canopy phenology. The PhenoCam Network coordinates the camera installation and data reporting/analyses across sites in the Americas, providing automated, near-surface remote sensing of canopy phenology across a range of ecosystems and climate zones. Use of PhenoCam images / data should follow the PhenoCam Data Use Policy .
No PhenoCam data for this siteGeoNEX Data Products
GeoNEX led by NASA Earth eXchange (NEX) is a collaborative effort for generating Earth monitoring products from the new generation of geostationary satellite sensors. GeoNEX has produced a suite of geostationary data products including surface reflectance, land surface temperature, surface solar radiation, and many others.
The GeoNEX Common Grid locates GeoNEX data in the geographic (latitude/longitude) projection. Pixels (grid cells) are created at regular 0.005°, 0.01°, and 0.02° resolutions.
GeoNEX pixels below cover the area 0.06° x 0.06° around and including site US-BFS, 34.1128, -117.7119.
