Description

 

In June of 2005 a web camera was installed just outside the boundary of Yosemite National Park looking south from the entrance at Tioga Pass across Dana Meadows toward Kuna Crest.  The system records images every five minutes during daylight hours. Each image is time stamped with the local date and time.  The camera is maintained by the Climate Research Division (CRD) at Scripps Institution of Oceanography.  It was installed with the help of Frank Gehrke of the California Cooperative Snow Surveys.  Each hour one image is sent via modem for display on the CRD Climate Applications Program website.  The data feed may be interrupted by winter storms which are notorious for taking out the power and/or the phone lines at Tioga Pass.
