Center for Sierra Nevada Water Information Systems
The Center for Sierra Nevada Water Information Systems provides tools for researchers and also State and Federal officials and employees. These tools allow users to explore remote sensing imagery and other data to make decisions and answer questions.
A tool in development and available now allows users to view snow and cloud cover in the Sierra Nevada mountains. The images were captured by the MODIS satellite. Sets of images are displayed by month. Multiple months be viewed simultaneously by selecting a range of dates. Users may also view several individual watershed basins with a higher resolution background which may help to identify snow locations more accurately. A link will be provided to access original MODIS image files.
