  • We started tower flux observation at hill-top of Poker Flat Research Range (Poker Flat site, 65o07'119.33"N, 147o25'33.18"W, 491m) from August 20, 2008, to obtain the comparable information of CO2 exchange at burned forest. The area was tussock tundra with gentle slope (Slope, 4 degree) facing to north-east where was black spruce forest and was burned in late June 2004. The average tree-ring age of 11 samples was 65yrs old, and most burned trunk of black spruce were left and was still standing. The under story of burned trunks was recovered after the fire and regenerated moss, vascular plants, and low bush plants were distributed in mid August, 2008. Site view of vegetation condition was shown in Fig.4.CO2 and energy fluxes were sampled at 10 Hz rate continuously, and the fluxes were calculated each 30 minutes intervals. The corrections of "Coordinate Transformation (Double Rotation)", "Spectrum Correction (Massman, 2000)", Data selection (remove spike noise on raw data)" were applied. However, we neglected the evaluation of storage term of CO2 near the ground, because there was gentle hill-slope and almost no tree generating the CO2 storage.
