Upper image is of an ultralight type airplane flying low and slow to collect images for rangeland assessment in Wyoming. Upper left image shows ground spectroradiometer being used to make measurements to help understand satellite images such as the scene (upper right) from the Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) on NASA’s Terra satellite for 12 May 2001 of a 60 by 60 km area showing the ARS Jornada Experimental Range outlined in yellow and the White Sand National Monument, upper right, in New Mexico. Lower left image is the installation of a remote sensor to measure soil and vegetation temperature at the ARS Grazinglands Research Lab, El Reno, Oklahoma. Lower right image shows the measurement of soil moisture using a hand-held probe concurrent with a truck tower passive microwave remote sensing system at Lamont, Oklahoma. The truck systems simulate instruments on the NASA Aqua and future satellites.

615 The Agricultural Research Service’s Remote Sensing Program: An Example of Interagency Collaboration
Paul J. Pinter, Jr., Jerry C. Ritchie, Jerry L. Hatfield, and Galen F. Hart

Partnerships among various federal, state, and private agencies have facilitated research and applications of remote sensing in agriculture.

619 Remote- and Ground-Based Sensor Techniques to Map Soil Properties

Edward M. Barnes, Kenneth A. Sudduth, John W. Hummel, Scott M. Lesch, Dennis L. Corwin, Ghenghai Yang, Craig S.T. Doughtry, and Walter C. Bausch

Ground-based, on-the-go sensors have been developed to rapidly map soil organic matter content, electrical conductivity, nitrate content, and compaction.

631 Remote Sensing Research in Hydrometeorology
William P. Kustas, Andrew N. French, Jerry L. Hatfield, Tom J. Jackson, M. Susan Moran, Al Rango, Jerry C. Ritchie, and Tom J. Schmugge

The research is separated into deriving from remote sensing (1) hydrometeorological state variables and (2) energy fluxes, particularly evapotranspiration which includes plant water stress.

647 Remote Sensing for Crop Management
Paul J. Pinter, Jr., Jerry L. Hatfield, James S. Schepers, Edward M. Barnes, M. Susan Moran, Craig S.T. Daughtry, and Dan R. Upchurch

Agricultural remote sensing, relying on research conducted by the USDA, Agricultural Research Service and cooperating institutions, is now poised to make major contributions to the management of water, nutrients, and pests in crops.

665 Crop Yield Assessment from Remote Sensing
Paul C. Doraiswamy, Sophie Moulin, Paul W. Cook, and Alan Stern

Satellite remotely sensed data provide a real-time assessment of the magnitude and variation of crop condition parameters, and this study investigates the use of these parameters as an input to a crop growth model.

675 Applications and Research Using Remote Sensing for Rangeland Management
E. Raymond Hunt, Jr., James H. Everitt, Jerry C. Ritchie, M. Susan Moran, D. Terrance Booth, and Gerald L. Anderson

ARS scientists are actively engaged in developing quantitative, repeatable, and low-cost methods to measure indicators of ecosystem health using remote sensing.

695 Remote Sensing Techniques to Assess Water Quality
Jerry C. Ritchie, Paul V. Zimba, and James H. Everitt

The integrated use of remotely sensed data, GPS, and GIS will enable consultants and natural resource managers to develop management plans for a variety of natural resource management applications.

705 Sensor Development and Radiometric Correction for Agricultural Applications
S. Moran, G. Fitzgerald, A. Rango, C. Walthall, E. Barnes, W. Bausch, T. Clarke, C. Daughtry, J. Everitt, J. Hatfield, K. Havstad, T. Jackson, N. Kitchen, W. Kustas, M. McGuire, P. Pinter, Jr., K. Sudduth, J. Schepers, T. Schmugge, P. Starks, and D. Upchurch

Examples of sensor development include on-site development of sensors and platforms, participation in cooperative research and development agreements with commercial companies, and membership on NASA science teams.
