What is the Desert Research Institute? Nevada System of Higher Education’s

Global Environment Research Institution

• Foster and conduct fundamental scientific, economic, social or educational investigations and applied research for industry, governmental or private agencies or individuals.

• Encourage and foster a desire in students and faculty to conduct research.

• Discover and develop talent for conducting research.

• Acquire and disseminate knowledge related to the projects undertaken.

• And to promote all research for higher education and State of Nevada

Founded in 1959, the primary purposes of the Institute are to:

• ~559 employees with ~155 research faculty

• Non-tenure / soft-money structure:

• Faculty are not tenured and generate their own salaries (no state-funded positions)

• Faculty bring ~$40M into Nevada’s economy!

• At any given time, DRI conducts about 300 research projects worldwide.

• Over 60 specialized labs & research facilities.

• DRI invests ~ $1.6M annually in non-state dollars for support of UNR and UNLV graduate students.

Entrepreneurial Culture and World Class Facilities

Research Structure Research Divisions:

• Atmospheric Sciences

• Earth and Ecosystem Sciences

• Hydrologic Sciences

Integrated Science Centers:

• Center for Advanced Visualization, Computation, and Modeling (CAVCaM)

• Rogers Center for Environmental Remediation and Monitoring (CERM)

• Watersheds and Environmental Sustainability (CWES)

• Clean Technologies and Renewable Energy Center (CTREC)

Assessing Climate Variability and Its Impact on Basin Wide ET and Vegetation

Desert Research Institute1 and University of Nevada Las Vegas2

Funded by the Southern Nevada Water Authority

Study Site

• Spring Valley in east central NV (100 km by 15 km)

• ET Estimation: empirical relationship between eddy covariance data and average growing season NDVI

• 5 sites in native shrub (greasewood and big sage), 1 mixed grass/shrub site and 2 irrigated agriculture

Spring Valley 1 (27% cover)

Spring Valley 2b (100% cover)

Methods • Landsat TM 5 scenes from the growing season

were calibrated, atmospherically corrected and normalized

• NDVI was calculated for each image date, cloud and shadow areas were replaced and average growing season NDVI was calculated

• Empirical relationship between annual tower ET and average growing season NDVI was determined for tower footprint areas.

• ET images were calculated and footprint pixels were compared to tower ET

(n = 30, r2 = 0.954)

Accuracy Assessment Results

This means that in the worst case ET estimation accuracy is 68 to 70% and in the best case 93%.
