Research PartnershipsTahoe Science Projects supported by SNPLMAUsing Remote Sensing to Monitor Water QualityOur current view of water quality in Lake Tahoe depends heavily on data records from two points within the lake and the points where some of the streams enter the lake. These point data do not provide the temporal and spatial detail needed to understand the changes taking place at different parts of the lake (such as the near-shore zone), and the linkage between the lake observations and the input sources. This study will put in place a system to utilize remotely sensed and field measurement data to quantify changes in water clarity measurements over the entire lake. Full Title: Monitoring past, present, and future water quality using remote sensing (RS) Proposal [pdf-191KB] Lead Researchers: S. Geoffrey Schladow, University of California, Davis; Simon J. Hook, Jet Propulsion Laboratory (NASA/JPL) Goals: Use remotely sensed (satellite) data to provide a quantitative management tool for lake-wide assessments of water quality and to link changes in water quality to discrete sources at the sub-watershed scale. Sites: remote sensing of entire lake; data on water quality and meteorology from four NASA buoys in the lake and a network of 12 meteorological stations. Timeframe: October 2007 through September 2009 (2 years) Figure: Preliminary near-shore clarity map derived from satellite imagery (ASTER) data Products
