US NED CHILI (Continuous Heat-Insolation Load Index)

AI-generated Key Takeaways

• The CHILI dataset provides a surrogate for the effects of insolation and topographic shading on evapotranspiration, calculated at early afternoon with sun altitude equivalent to equinox.

• This dataset is part of the Conservation Science Partners (CSP) Ecologically Relevant Geomorphology (ERGo) Datasets, intended for climate adaptation planning by providing data on stable landscape features.

• The dataset is based on the USGS's 10m NED DEM and is available with a pixel size of 10 meters.

• The dataset includes a constant band representing the NED-derived CHILI index, scaled from 0 (very cool) to 255 (very warm).

• The dataset is available from 2006 to 2011 and is provided under the CC-BY-NC-SA-4.0 license.

Description

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.
