New paper on space-time structure of subcanopy flow in forests published

Space-time structure of air flow and temperature Publication: A new paper was published in the journal Boundary-Layer Meteorology analyzing the space-time structure of the air flow and temperature signal in a very dense forest canopy in the Oregon Coast Range, which is located in moderately complex terrain. Among the results is a novel space time diagram showing the generalized characteristics of the air flow and temperature signals. The mismatch in time scales of the predominant motions contributing to both signals may explain why researchers have not been able to find a conclusive answer to the question if the inclusion of advective terms in the mass balance equations leads to improved results. Furthermore, spatial temperature gradients were found  to be non-linear and sensitive to the sensor network configuration and method of interpolation. The results may have an influence on the design of future energy- and mass balance studies, as well as provide perspective on the re-evaluation of historic data sets for the flux and micrometeorological communities.
