Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Liquid water content of coastal California fog events, San Mateo County

Liquid water content (LWC) measurements were collected during coastal fog events using specialized fog water collection units outfitted with six flat panel mesh collector frames. Simultaneous meteorological measurements were collected for four variables: wind, temperature, humidity, and solar radiation. The dataset includes ~12,000 records for two sites. Site one is in a grassl
