Observatory design in the mountain west: scaling measurements & modeling in the San Joaquin
Valley & Sierra Nevada
Scope: Establish a “virtual” hydrologic observatory, & provide direction for building new infrastructure in an actual observatory.
Focus: Build infrastructure for improving the knowledge base for sound hydrologic management in the Sierra Nevada, San Joaquin Valley & across the West
Greater San Joaquin R. basin, encompassing American R. to north through Kings R. in south
PI: Roger Bales, UC Mercedhttps://eng.ucmerced.edu/snri

San Joaquin virtual observatory
Observatory design concept: Establish intensive measurements at ground-based instrument clusters, integrated with broad coverage offered by satellite remote sensing, plus operational networks.
NIMS payload of sensors deployed in San Joaquin R.
Science challenge: Scaling between instrument clusters is a major challenge. Basing an observatory on instrument clusters at representative points across the landscape recognizes that it is logistically infeasible to measure everything, everywhere, all the time. Instrument clusters co-locate key measurements, in order to illuminate linkages among processes within each cluster's relatively small footprint.

San Joaquin virtual observatorySpecific aims– Formulate basin-scale measurement & modeling strategies for priority
research, through analysis of existing operational & research data– Assess different instrument cluster designs to provide the ground-based
measurements needed for hydrologic process research
Example data− Daily satellite snowpack
products− Streamflow, weather &
snow data from operational & research networks
− Soil moisture & water quality data from research networks
− Topography, vegetation characteristics & other spatial data Merced & Tuolumne R. sub-basins are
the focus for this project
