Dry nitrogen deposition estimates over a forest experiencing free air CO2 enrichment

Abstract: The quantification of atmospheric additions of nitrogen (N) to an ecosystem is often desirable, but difficult for many locations including many ecological manipulation experiments. Ideal methodologies for the complete and chemically speciated quantification of dry N deposition (e.g. tunable diode laser absorption spectrometer, thermaldissociation laser-induced fluorescence) are expensive, technologically challenging to maintain, and rarely colocated with important global change manipulation experiments.

“…9) calculates a net daily deposition of 0.14 mg (N) m −2 day −1 . These are of the same order of magnitude as the handful of previously reported summertime NO y fluxes from other forest sites across North America (Sparks et al, 2008;Munger et al, 1998;Hogg, 2007). Table 1 compares mean results from previous NO y eddy covariance flux studies in mg (N) m −2 day −1 , with a focus on summertime observations.…”

“…Munger et al (1998) describe the budget for Harvard Forest using NO y eddy covariance flux data collected from 1990 to 1996, and show that, on an annual basis, dry deposition contributes 34 % of total NO y inputs; the same paper summarizes data collected during the summer of 1990 over a black spruce woodland in northern Quebec which show that contributions of dry deposition are roughly the same. Sparks et al (2008) report a much higher dry NO y deposition contribution to total nitrate on an annual basis of around 60 % above a North Carolina pine plantation. Other studies using eddy covariance have applied novel instruments to directly determine the contribution of individual species over short-term (several months or less) intensive field campaigns at a number of sites across North America (Horii et al, 2004;Turnipseed et al, 2006;Farmer and Cohen, 2008;Wolfe et al, 2009;Min et al, 2012;Zhang et al, 2012).…”

“…However, a recent field study over a coniferous forest (Turnipseed et al, 2006;Sparks et al, 2008) estimated that HNO 3 accounted for only w24% of the NO y flux and PAN exhibited a close portion of w20%. Zhang et al (2009) investigated the total nitrogen flux budget over eight rural sites across eastern Canada, and estimated that HNO 3 constituted less than half of the NO y flux (46%), and the flux from other measured gaseous nitrogen species (NO 2 þ PAN þ PPN) were also a significant portion (35%).…”
