Observations of radiation exchange above and below Amazonian forest.

W. James Shuttleworth

Research output: Contribution to journalArticlepeer-review


Measurements of short and long wave components of the radiation budget were made above and below the tropical forest in the Amazon Basin of a total of 203 hours. Albedo was 12.25 + or - 0.2%. The net outward flux of longwave radiation was approximately 30W/sq.m, and fairly constant over the day. The relationship between net radiation, R, and solar radiation, S, is adequately described by the expression R = (0.858 + or - 0.006)S - (35.0 + or - 1.9) W/sq m. The fraction of solar radiation reaching the bottom of the canopy was low, 1.15%; net radiation in this position is consistent with low soil heat flux and low soil evaporation.-from STAR, 22(21), 1984
