Multiple causes for the malformed frog phenomenon Multiple causes for the malformed frog phenomenon
Progress has been made in understanding the malformed frog problem, yet we still cannot identify with assurance specific causes of malformations at particular locations. To address this problem we assembled a team of specialists and present here results on geographic distribution, water quality, parasite infection, and morphological patterns from Minnesota malformed frog sites and...

Development of stochastic modeling systems using deterministic models and GIS: Principles and a case study in the Atlantic Zone of Costa Rica Development of stochastic modeling systems using deterministic models and GIS: Principles and a case study in the Atlantic Zone of Costa Rica
The most important requirements for large-area environmental modeling are a tight integration between models and data, and a close match of the spatial scale at which the model is developed with the scale at which the model is to be applied. To better match the scale of data with that of the model, we propose a set of principles for the development of stochastic modeling systems based on...

Deriving annual integrated NDVI greenness at 30 m spatial resolution Deriving annual integrated NDVI greenness at 30 m spatial resolution
Temporal greenness matrics have been found useful for characterizing vegetation phenology, and have been used to discriminate vegetation cover types and to estimate key vegetation attributes including percent cover and green biomass. So far, however, such matrics have been calculated only from coarse resolution satellite data. Intermediate spatial resolution satellites like Landsat...

Land cover characterization and mapping of continental southeast Asia using multi-resolution satellite sensor data Land cover characterization and mapping of continental southeast Asia using multi-resolution satellite sensor data
Land use/land cover change, particularly that of tropical deforestation and forest degradation, has been occurring at an unprecedented rate and scale in Southeast Asia. The rapid rate of economic development, demographics and poverty are believed to be the underlying forces responsible for the change. Accurate and up-to-date information to support the above statement is, however, not...

The role of C3 and C4 grasses to interannual variability in remotely sensed ecosystem performance over the US Great Plains The role of C3 and C4 grasses to interannual variability in remotely sensed ecosystem performance over the US Great Plains
Time integrated normalized difference vegetation index (ΣNDVI) derived from National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) multi-temporal imagery over a 10-year period (1989–1998) was used as a surrogate for primary production to investigate the impact of interannual climate variability on grassland performance for central and...

Water vapour correction of the daily 1 km AVHRR global land dataset: Part I validation and use of the Water Vapour input field Water vapour correction of the daily 1 km AVHRR global land dataset: Part I validation and use of the Water Vapour input field
An atmospheric correction algorithm developed for the 1 km Advanced Very High Resolution Radiometer (AVHRR) global land dataset was modified to include a near real-time total column water vapour data input field to account for the natural variability of atmospheric water vapour. The real-time data input field used for this study is the Television and Infrared Observational Satellite...

Estimating Meher crop production using rainfall in the 'Long Cycle' region of Ethiopia Estimating Meher crop production using rainfall in the 'Long Cycle' region of Ethiopia
Meher season crop production is well correlated with April-May rainfall in the Ethiopian 'long cycle' crop growing region. This relationship is used to estimate 2003 Meher small farmer gross production at 87 =B1 10 million quintals (8.7 million MT2 =B1 1 million MT) of cereals, pulses and other crops, using data from the Central Statistical Authority (CSA). Assuming recent levels of...

The National Map: from geography to mapping and back again The National Map: from geography to mapping and back again
When the means of production for national base mapping were capital intensive, required large production facilities, and had ill-defined markets, Federal Government mapping agencies were the primary providers of the spatial data needed for economic development, environmental management, and national defense. With desktop geographic information systems now ubiquitous, source data...
