Title: Gridded Population of the World  (GPW) Version 1

Source: NCGIA and CIESIN

Author: Waldo Tobler, CIESIN

Spatial Coverage: Global

Size: 2275005575 bytes

Description: Gridded Population of the World (GPW), Version 1.0 (v1) consists of estimates of human population for the year 1994 by 5 arc-minute grid cells. The 4 products are raw and smoothed population counts and density, all of which are available in several GIS-compatible data formats at the global and continent levels. A straight majority rule gridding algorithm, utilizing approximately 19,000 national and sub-national administrative units, is used to assign population values to grid cells. The smoothing is performed using the pycnophylactic technique, which redistributes population counts among grid cells within administrative units by attracting population towards high-count areas.

Date of Publication: 2000

Spatial Coverage: Global

Temporal Coverage: 1990, 1995

Size: 12.89 GB

Description: Gridded Population of the World (GPW) version 2 provides estimates of the population of the world in 1990 and 1995, both population counts (raw counts) and population densities (per square km). National figures have been reconciled to be consistent with United Nations population estimates for those years; unadjusted data are also available. Both images and data are accessible and downloadable. Developed in 1999-2000, GPW version 2 incorporates a number of improvements to the original version of this popular dataset.

Title: Integrated Model for the Assessment of the Greenhouse Effect (IMAGE) 2.0 and Associated Scenarios

Source: IMAGE Project, RIVM, the Netherlands

Author: Netherlands National Institute of Public Health and Environmental Protection (RIVM)

Date of Publication: 1994

Spatial Coverage: Global

Temporal Coverage: 1900-2100

Size: 1.516 GB

Description: The IMAGE 2.0 model, a multi-disciplinary, integrated model is designed to simulate the dynamics of the global society-biosphere-climate system. The objectives of the model are to investigate linkages and feedbacks in the system, and to evaluate consequences of climate policies. Dynamic calculations are performed to year 2100, with a spatial scale ranging from grid (0.5 degree x 0.5 degree latitude-longitude) to world regional level, depending on the sub-model. The model consists of three fully linked sub-systems: Energy-Industry, Terrestrial Environment, and Atmosphere-Ocean. The fully linked model has been tested against data from 1970 to 1990, and after calibration can reproduce the following observed trends: regional energy consumption and energy-related emissions, terrestrial flux of CO2 and emissions of greenhouse gases, concentrations of greenhouse gases in the atmosphere, and transformation of land cover.
