Increasing concentrations of atmospheric CO2 decrease stomatal conductance of plants and thus suppress canopy transpiration. The climate response to this CO2-physiological forcing is investigated...
Planning for Distributed Earth Science Data Processing (2008)
Petr Votava, Keith Golden, Ramakrishna Nemani
An important challenge in Earth science processing is the large volume and distributed nature of the data required by many processing algorithms. Despite the increase in available bandwidth over the...
An Agent-Based Interface to Terrestrial Ecological Forecasting (2008)
Keith Golden, Ramakrishna Nemani, Wanlin Pang, Petr Votava, Oren Etzioni
Abstract — This paper describes a flexible agent-based ecological forecasting system that combines multiple distributed data sources and models to provide near-real-time answers to questions about...
The 2007 Eastern US Spring Freeze: Increased Cold Damage in a Warming World (2008)
Lianhong Gu, Paul J. Hanson, W. Mac Post, Dale P. Kaiser, Bai Yang, Ramakrishna Nemani, ...
Plant ecologists have long been concerned with a seemingly paradoxical scenario in the relationship between plant growth and climate change: warming may actually increase the risk of plant frost...
Global Distribution and Density of Constructed Impervious Surfaces (2007)
Christopher D. Elvidge, Benjamin T. Tuttle, Paul C. Sutton, Kimberly E. Baugh, Ara T. Howard, Cristina Milesi, ...
We present the first global inventory of the spatial distribution and density ofconstructed impervious surface area (ISA). Examples of ISA include roads, parking lots,buildings, driveways, sidewalks...
Automating the processing of earth observation data (2003)
Keith Golden, Wanlin Pang, Ramakrishna Nemani, Petr Votava
NASA’s vision for Earth science is to build a “sensor web”: an adaptive array of heterogeneous satellites and other sensors that will track important events, such as storms, and provide...
Evaluation of Decision Trees for Cloud Detection from AVHRR Data (1998)
Shiffman, Smadar, Nemani, Ramakrishna
Automated cloud detection and tracking is an important step in assessing changes in radiation budgets associated with global climate change via remote sensing. Data products based on satellite...
