Compare this with today's conditions! Click the link below. The webcam looks west from the Giant Forest. Rarely can you see both the San Joaquin Valley and the Coast Range beyond that. In this photo from early summer, a gray layer of polluted air can be seen forming over the valley. With increasing air pollution blowing up into the Sierra Nevada from the Bay Area and the Valley, very clear days are becoming ever more rare.
The Giant Forest webcam is one of a network of digital cameras at many parks that help to track conditions and to educate the public on air-quality issues. These cameras often show visibility impairment due to air-quality issues, whether natural (such as wildfire) or human-caused pollution. Because the cameras are part of air-quality monitoring sites, their web pages display other information along with the latest photo: current levels of ozone, particulate matter, or sulfur dioxide air pollutants, visual range, and weather conditions.
NEW! Charts of the last ten days of hourly weather, ozone, particulate matter, or sulfur dioxide data are now available. To view, click the blue "10-day Charts" tab now appearing on the right side of each park's web-camera home page. The digital photos are usually updated every 15 minutes, while air-quality data values are revised hourly. Go to the Giant Forest Webcam page > > > |
