About the data available in this tool
Data used in this tool includes inputs and outputs from the
Integrated Ecosystem Management
(IEM) project, which originally sought to couple several models: the
Terrestrial Ecosystem Model (TEM), the Geophysical Institute
Permafrost Lab (GIPL) model, and ALFRESCO, a stochastic wildfire and

What datasets are shown in this tool?
Temperature & Precipitation
Elevation data is derived from the
30–meter digital elevation product. Elevation data for points is
averaged across a 1km square, and elevation for areas is averaged
across the entire area.
This tool doesn’t offer the full range of data produced for the
IEM project. If you are looking for models or scenarios not present on
this site, you can download source data.
Note that the precision of the data shown in this tool depends on the
grid resolution (pixel size) of the underlying dataset. Temperature
and precipitation products are at 2km resolution, the GIPL outputs are
4km and ALFRESCO outputs are at 1km resolution.
What places are available in this tool?
The highlighted area on the map shows the full domain of the IEM
research project. Within this area, this tool has a variety of places
which can be chosen for reports:
- watersheds/hydrological units at the HU-8 level
(subbasin), searchable by name or HUC code (“Middle Copper
River” or “HUC 19020102”, for example),
- protected areas such as National Parks, National
Forests, Wilderness Areas, National Wildlife Refuges, State Parks
and more, searchable by name and agency (NPS, USFS, etc),
- Alaska Native Corporation geographic boundaries
- Alaska Fire Management Units
- Ethnolinguistic regions of Alaska
- Alaska Climate Divisions
- First Nation Traditional Territories of the Yukon
- Alaska Game Management Units (GMUs), e.g. GMU19a, etc.
