| Zusammenfassung |
| Observation and quantification of the Earth's surface is undergoing a
revolutionary change due to the increased spatial resolution and extent
afforded by light detection and ranging (lidar) technology. As a
consequence, lidar-derived information has led to fundamental discoveries
within the individual disciplines of geomorphology, hydrology, and ecology.
These disciplines form the cornerstones of critical zone (CZ) science, where
researchers study how interactions among the geosphere, hydrosphere, and
biosphere shape and maintain the "zone of life", which extends from the
top of unweathered bedrock to the top of the vegetation canopy. Fundamental
to CZ science is the development of transdisciplinary theories and tools
that transcend disciplines and inform other's work, capture new
levels of complexity, and create new intellectual outcomes and spaces.
Researchers are just beginning to use lidar data sets to answer
synergistic, transdisciplinary questions in CZ science, such as how CZ
processes co-evolve over long timescales and interact over shorter timescales to create thresholds, shifts in states and fluxes of water, energy,
and carbon. The objective of this review is to elucidate the transformative
potential of lidar for CZ science to simultaneously allow for quantification
of topographic, vegetative, and hydrological processes. A review of 147
peer-reviewed lidar studies highlights a lack of lidar applications for CZ studies as 38 % of the studies were focused in
geomorphology, 18 % in hydrology, 32 % in ecology, and the remaining
12 % had an interdisciplinary focus. A handful of exemplar
transdisciplinary studies demonstrate lidar data sets that are well-integrated with other observations can lead to fundamental advances in CZ science, such as
identification of feedbacks between hydrological and ecological processes
over hillslope scales and the synergistic co-evolution of landscape-scale CZ
structure due to interactions amongst carbon, energy, and water cycles. We
propose that using lidar to its full potential will require numerous
advances, including new and more powerful open-source
processing tools, exploiting new lidar acquisition technologies, and
improved integration with physically based models and complementary in situ and
remote-sensing observations. We provide a 5-year vision that advocates
for the expanded use of lidar data sets and highlights subsequent potential
to advance the state of CZ science. |
