Sea surface temperature monitor and predict the El Niño phenomenon. Weather satellites have been available to determine sea surface temperature information since 1967, with the first global composites created during 1970. Since 1982, satellites have been increasingly utilized to measure SST and have allowed its spatial and temporal variation to be viewed more fully. Satellite measurements of SST are in reasonable agreement with in situ temperature measurements. The satellite measurement is made by sensing the ocean radiation in two or more wavelengths within the infrared part of the electromagnetic spectrum or other parts of the spectrum which can then be empirically related to
Skyline-to-the-Sea Trail passing through a defunct quarry, and terminating in Sanborn-Skyline County Park. This trail would connect to the Skyline-to-the-Sea Trail via a completed section of the Bay Area Ridge Trail. The quarry is owned by the Santa Clara County Roads and Airports Department, which is conducting feasibility studies of this plan. Skyline-to-the-Sea Trail The Skyline-to-the-Sea Trail is a 29.5-mile (47.2-kilometre) hiking trail that descends from the ridge of the Santa Cruz Mountains in California to the Pacific Ocean, passing through Castle Rock State Park and Big Basin Redwoods State Park. Big Basin is California's oldest state park. It contains beautiful waterfalls
