CHILI is a surrogate for effects of insolation and topographic shading on
evapotranspiration represented by calculating insolation at early afternoon,
sun altitude equivalent to equinox. It is based on the USGS's 10m NED DEM
(available in EE as USGS/NED).
The Conservation Science Partners (CSP) Ecologically Relevant Geomorphology
(ERGo) Datasets, Landforms and Physiography contain detailed, multi-scale
data on landforms and physiographic (aka land facet) patterns. Although
there are many potential uses of these data, the original purpose for these
data was to develop an ecologically relevant classification and map of
landforms and physiographic classes that are suitable for climate adaptation
planning. Because there is large uncertainty associated with future climate
conditions and even more uncertainty around ecological responses, providing
information about what is unlikely to change offers a strong foundation for
managers to build robust climate adaptation plans. The quantification of
these features of the landscape is sensitive to the resolution, so we
provide the highest resolution possible given the extent and characteristics
of a given index.
