Modelling the impacts of climate and land use change on tropical water resources


This database provides information and data from the Tropical Hydrology and Cloud Forests Project.

The data represent the results of a research project carried out by Dr. Mark Mulligan at Kings College London and Dr Sophia Burke of AMBIOTEK and are derived from a variety of original data sources.

A pan-tropical water balance model was developed and the implications of historic forest loss in the tropical upland and lowlands examined. The implications of historic and scenario climates on water resource availability are also examined.

For data distribution, the entire tropics are broken up into a series of tiles. Each of these grids contains a 1024 by 1024 km tile of approx. 1km resolution data. The data represent the results of a research project and are derived from a variety of original data sources. All data are in the Geographic Coordinate System, WGS84 datum and are distributed as zipped ARCASCII files.
