Representing twentieth century space-time climate variability, part 1: development of a 1961-90 mean monthly terrestrial climatology
- Journal of Climate
, 1999
"... The construction of a 0.58 lat 3 0.58 long surface climatology of global land areas, excluding Antarctica, is described. The climatology represents the period 1961–90 and comprises a suite of nine variables: precipitation, wet-day frequency, mean temperature, diurnal temperature range, vapor pressur ..."

Uncertainty estimates in regional and global observed temperature changes: A new dataset from 1850
- J. Geophys
, 2006
"... The historical surface temperature dataset HadCRUT provides a record of surface temperature trends and variability since 1850. A new version of this dataset, HadCRUT3, has been produced; benefiting from recent improvements to the sea-surface temperature dataset which forms its marine component, and ..."

Spacetime Constraints
- Computer Graphics
, 1988
"... Spacetime constraints are a new method for creating character animation. The animator specifies what the character has to do, for instance, "jump from here to there, clearing a hurdle in between;" how the motion should be performed, for instance "don't waste energy," or &quo ..."

i-LAND: An interactive Landscape for Creativity and Innovation
- CHI'99
, 1999
"... We describe the i-LAND environment which constitutes an example of our vision of the workspaces of the future, in this case supporting cooperative work of dynamic teams with changing needs. i-LAND requires and provides new forms of human-computer interaction and new forms of computer-supported coope ..."

Second simulation of the satellite signal in the solar spectrum, 6S: An Overview
, 1997
"... Remote sensing from satellite or airborne platforms of land or sea surfaces in the visible and near infrared is strongly affected by the presence of the atmosphere along the path from Sun to Target (surface) to Sensor. This paper presents 6S (Second Simulation of the Satellite Signal in the Solar S ..."

Use of U.S. croplands for biofuels increases greenhouse gases through emissions from land-use change‖, Science 319:1238–40
- Sustainable fuels from Algae, Presentation to Committee on the Sustainable Development of Algal Biofuels, National Research Council, June 13, 2011, Washington D.C
, 2008
"... Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert fore ..."

forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels. Using a worldwide agricultural model to estimate emissions from land use change, we found that corn-based ethanol, instead of producing a 20 % savings, nearly doubles greenhouse emissions over 30 years
Global land cover mapping from MODIS: algorithms and early results,
- Remote Sensing of Environment,
, 2002
"... Abstract Until recently, advanced very high-resolution radiometer (AVHRR) observations were the only viable source of data for global land cover mapping. While many useful insights have been gained from analyses based on AVHRR data, the availability of moderate resolution imaging spectroradiometer ..."

(MODIS) data with greatly improved spectral, spatial, geometric, and radiometric attributes provides significant new opportunities and challenges for remote sensing-based land cover mapping research. In this paper, we describe the algorithms and databases being used to produce the MODIS global land cover
Multi-agent systems for the simulation of land-use and land-cover change: a review
- Annals of the Association of American Geographers
, 2003
"... This paper presents an overview of multi-agent system models of land-use/cover change (MAS/LUCC models). This special class of LUCC models combines a cellular landscape model with agent-based representations of decisionmaking, integrating the two components through specification of interdependencies ..."

the standard atmosphere and land resolution of 18 results in the sea surface temperature biases in the major upwelling regions being comparable to the 1.48-resolution CCSM3. Two changes to the deep convection scheme in the atmosphere component result in CCSM4 producing El Niño–Southern Oscillation variability
