Jun-Aug 2002-2003 Sylvania daytime aggregated flux footprint climatology, contours are logarithmic influence isopleths, landcover is Michigan Digital GIS Library, Landsat classified image 2001
Jun-Aug 2002-2003 Sylvania nighttime aggregated flux footprint climatology, contours are logarithmic influence isopleths, landcover is Michigan Digital GIS Library, Landsat classified image 2001
Jun-Aug 2002-2003 Sylvania 30-degree wind sector bin average footprint land cover influence - nighttime. Maximum mixed old-growth forest (hemlock / maple) and minimal water influence found in 180-270 degree sector
Jun-Aug 2002-2003 Sylvania 30-degree wind sector bin average footprint land cover influence - daytime. Influence function mostly similar in wind directions – more old growth in SW, minimum in 0-90 sector. Daytime influenced by closer in sugar maple more than nighttime
Jun-Aug 2002-2003 Sylvania bin average footprint influence land cover as a function of nighttime NEE (u* screened) normalized to 15 C. Low NEE values influenced more by water and deciduous.
Jun-Aug 2002-2003 Sylvania bin average footprint influence land cover as a function of daytime NEE. Variability in footprint influence with NEE is minimal.
Jun-Aug 2002-2003 Sylvania footprint influence landcover decomposed NEE as a function of deciduous sugar maple, mixed conifer-deciduous old-growth maple-hemlock and wetland.
