Snow influences the land-surface water budget. Snow measurements are needed both to study climate and to predict drought, flooding, and water availability.
Monitoring changes in vegetation is important for climate and hydrologic modeling applications, validation of satellite estimates of land surface conditions, and testing of ecohydrological hypotheses.
Soil moisture affects the partitioning of precipitation into runoff, evapotranspiration and deep drainage and the fluxes of energy and carbon between the land surface and atmosphere.

In the past water cycle research at CU has been funded by NSF (AGS 0740515, EAR 0948957, AGS 0935725, EAR1144221) and NASA (NNH09ZDA001N, NNX11AL50H, NNX12AK21G, NNH10ZDA001N, NNX10AU84G, NNX13AF43G, and NNX11AR72G).
Some of this material is based on data, equipment, and engineering services provided by UNAVCO through the GAGE Facility with support from NSF and NASA under NSF EAR-1261833.
The spotlight website was developed with support from NSF EAR-1144221, NASA NNX12AK21G, and the UNAVCO Education and Outreach Program (funded by NASA and NSF under NSF Coop. Agreement EAR-0735156). It is maintained by Kristine Larson.
Any opinions, findings, and conclusions or recommendations are ours and do not necessarily reflect the views of NSF, NASA, UNAVCO, or CU.

Reflected GPS signals are sensitive to snow, soil moisture, and vegetation. The PBO H2O Data Portal makes hydrologic products based on GPS data available directly through your web browser. For more information on how these environmental products were created and for tutorials on how to retrieve data, please see the portal documentation.
