Historical and Future Projections of land cover distribution dynamics in the Tanana River Flats, Alaska from 1950 to 2100

These data contain historical and future projections of percent land cover from 1950 to 2100, as simulated by the Alaska Thermokarst Model for the boreal region. The data are 1km spatial resolution. The climate data used to drive the model simulations are from the Climate Research Unit, Time Series 4.0 (CRU_TS40) for the historical period (1950 to 2015), and from RCP 8.5 and global circulation models NCAR-CCSM4 and MRI-CGCM3 for the projected period (2016 to 2100).

Datasets from the years 1950, 2000, 2050, and 2100 are provided. Annual maps are available upon request.

Land cover types:
Bar | Barren
Con | Coniferous forest
Dec | Deciduous Forest
Shrub | Shrubland
YB | Young bog
OB | Old bog
YF | Young fen
OF | Old fen
WTR | Open water
