Spatial Scale And Landscape Heterogeneity Effects On Fapar In An Open-Canopy Black Spruce Forest In Interior Alaska
Kobayashi, H., Suzuki, R., Nagai, S., Nakai, T., Kim, Y.

Black spruce forests dominate the land cover in interior Alaska. In this region, satellite remote sensing of ecosys- tem productivity is useful for evaluating black spruce for- est status and recovery processes. The fraction of absorbed photosynthetically active radiation (FAPAR) by green leaves is a particularly important input …

Characteristics Of Evapotranspiration From A Permafrost Black Spruce Forest In Interior Alaska
Nakai, T., Kim, Y., Busey, R. C., Suzuki, R., Nagai, S., Kobayashi, H., Park, H., Sugiura, K., Ito, A.

Here, the year 2011 characteristics of evapotranspiration and the energy budget of a black spruce forest underlain by permafrost in interior Alaska were explored. Energy balance was nearly closed during summer, and the mean value of the daily energy balance ratio (the ratio of turbulent energy fluxes to available energy) from June …

Sensitivity Of The Backscatter Intensity Of Alos/Palsar To The Above-Ground Biomass And Other Biophysical Parameters Of Boreal Forest In Alaska
Suzuki, R., Kim, Y., Ishii, R.

We investigated the potential of ALOS/PALSAR for estimating the above-ground biomass (AGB) and other biophysical pa- rameters (tree height, diameter at breast height (DBH), and tree stand density) in the boreal forest of Alaska. In July 2007, forest surveys were conducted along a southenorth transect (150 W) to profile the ecotone …

Seasonal Changes In Camera-Based Indices From An Open Canopy Black Spruce Forest In Alaska, And Comparison With Indices From A Closed Canopy Evergreen Coniferous Forest In Japan
Nagai, S., Nakai, T., Saitoh, T. M., Busey, R. C., Kobayashi, H., Suzuki, R., Muraoka, H., Kim, Y.

Evaluation of the carbon, water, and energy balances in evergreen coniferous forests requires accurate in situ and satellite data regarding their spatio-temporal dynamics. Daily digital camera images can be used to determine the relationships among phenology, gross primary productivity (GPP), and meteorological parameters, and to …
