Science Dept., Optical Sciences Center, and School of Renewable Natural Resources), and University of 
Maryland (Dept, of Meteorology). The WG’92 Experiment was organized by ARS U.S. Water Conservation 
Laboratory and CEMAGREF-ENGREF-France, with ongoing support of WGEW provided by the ARS Southwest 
Watershed Research Center. WG’92 was made possible in part by the cooperative spirit of EOSAT Corp. and 
the European Space Agency who provided Landsat TM and ERS-1 SAR images at no cost. In addition to the 
authors, scientists from many organizations contributed to the SALSA-MEX experimental conceptualization, 
including Rutgers Univ., USGS-Denver, Univ. of Arizona (Dept, of Hydrology and Water Resources), LERTS- 
France, Utah State Univ., Ft. Huachuca, Jet Propulsion Lab., and CIDESON-Mexico. We express our special 
appreciation to the staff and on-site personnel of WGEW, operated by the ARS Southwest Watershed Research 
Center in Tucson, Arizona. Partial funding for these experiments was provided by the NASA Interdisciplinary 
Research Program in Earth Sciences (NASA Ref. Num. IDP-88-086), the NASA Eos Program (NASA Ref. Num. 
NAG-W2425), and NSF (BSC-8920851), and their support is gratefully acknowledged.
