abstract = "{West Africa plays key roles in global climate and shows one of the
strongest variations in hydro-climatic conditions. As it turns
out, the region appears to be underrepresented in the existing
compendium of Earth science and hydrology-focused journal papers
when it comes to significant discussion on terrestrial hydrology
and freshwater science. This prominent gap is largely
precipitated by increasing number of constraints that include
lack of considerable and robust investments in gauge
measurements for meteorological and hydrological applications,
poor funding of research institutions and other disincentives,
among other factors. In this manuscript, the challenges and
problems in large-scale terrestrial hydrology-focused
investigation in West Africa are reviewed. Using a dossier of
some recent contributions in the field of remote sensing
hydrology, this review also highlights some of the progress in
terrestrial hydrology and the opportunities that exist for
hydro-geodetic research in West Africa that leverage on
sustained investments in satellite geodetic missions. It is
noted that West Africa is still a pristine environment for
hydrology-focused research and can benefit from recent
advancements in sophisticated space agency programs such as the
Gravity Recovery and Climate Experiment, which undoubtedly has
revolutionized terrestrial hydrology research around the world
for nearly two decades. Given the poor density of gauge stations
and limited ground observations, hydrological research in West
Africa is expected to benefit more from independent space
observations and multi-resolution data. This is because the lack
of sufficient in-situ data for the parameterizations and
adequate initialization of outputs from hydrological models and
reanalysis data for hydrological applications results in poor
representation of the West African land surface and hydrological
state variables. To further improve our contemporary
understanding of West Africa's terrestrial hydrology, the
continued evaluation/validation of these observations and space-
borne measurements is advocated.}",
