Dr. Geoffrey Henebry of SDSU is an ecologist whose research focuses on developing theory and technique to improve the analysis of image time series and the modeling of ecological phenomena. He is currently investigating the effects of the collapse of the Soviet Union on the arrival of spring in European Russia and Central Asia and the consequences for regional precipitation patterns. He also works on a USDA-funded project modeling the interannual variation in forage production in the grasslands of the Northern Great Plains and serves as a co-investigator on the multidisciplinary Sand Hills Biocomplexity project, funded by the NSF, which studies the processes that enable the stability of the largest dune field in the Western Hemisphere. As a Fulbright Senior Research Fellow at the Brazilian Space Agency in 1993-94, Dr. Henebry used imaging radar to investigate flooding patterns in the Pantanal Matogrossense, the largest wetland on the planet. Dr. Henebry is a member of NASA's Land Use Land Cover Change Science Team and the Northern Eurasia Earth Science Partnership Initiative Science Team. He entered the field of ecological remote sensing while serving as a post-doctoral fellow with the Konza Prairie Long Term Ecological Research project at Kansas State University. He earned a Ph.D. and a M.S., both in Environmental Sciences, from the University of Texas at Dallas, and a B.A. in Liberal Arts from St. John's College in Santa Fe.

Fig. 1. Differences in land surface phenology across the Northern Great Plains as revealed by MODIS NDVI a 1 km resolution. This false color composite places three 16-day composites in the red, green, and blue color planes: red = 08MAY04; green = 27JUL04; blue = 08MAR04.
Fig. 2. A shaded relief map showing 112 large swaths of devegetation caused by hailstreaks during the 1900s. Color denotes the month of occurence. The AVHRR NDVI datasets used to identify the devegetated areas were produced at the USGS National Center for Earth Resources Observation and Sciences. Many of these devegetation events (20%) covered more than 1,000 km² and the largest covered more than 8,000 km².
