USGS Land Cover Change StudyAlaska-Canada Climate-Biome ShiftPermafrost DynamicsNorth Slope Climate AnalysisSitka HydropowerArctic Sea Ice TrendsAlaska Integrated Ecosystem ModelIPY – Ecosystems & SocietyDEC – Oil Spill Preparedness
Network Collaboration
Example - Primary Data Are
TemperaturePrecipitation
Days of freeze/thawGrowing season length
Evapotranspiration
Example - Models
To "run" a model, the planet is a 3D
grid,
Apply the basic equations, and
Evaluate the results.
