Modelling the impacts of climate and land use change on pantropical
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

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.
Data available (covering entire tropics, not only cloud
forest areas)
Forests
allf - current tropical forest fractional cover (%)
forloss - fractional forest cover loss to date (%)
cf - current fractional cloud forest cover (%)
cfloss - fractional cloud forest cover loss to date (%)
unprotcf - unprotected remaining cloud forest cover (%)
Climate
cloud - annual average cloud frequency (%)
wprec - wind driven precipitation inputs (mm/year)
annevap - annual total evapotranspiration (mm/year)
Hydrology
annbal - annual water balance (wind driven rainfall minus evapo-transpiration)
(mm/year)
sensluc - hydrological sensitivity to land use change (change
in water balance per unit change in land cover fraction) (mm/%)
