Study of N 2 O Flux over Central Amazon Monica Tais Siqueira D'Amelio (IPEN/LQA) Luciana Vanni Gatti (IPEN/LQA) John Bharat Miller (NOAA/ESRL) Filipe Vaz (IPEN/LQA) Andrew Crottwell (NOAA/ESRL) Pieter Tans (NOAA/ESRL)

N 2 O Sources and Sinks N 2 O is the 3 rd most important anthropogenic greenhouse gas. Life time: 120 years Main sources: Nitrification and denitrification in soils: 9-31 TgN 2 Oyr -1 Ocean: 9-19 TgN 2 Oyr -1 Agricultural soil: 19.5 TgN 2 Oyr -1 (77% of anthropogenic contribution) Main sinks Decomposition in stratosphere by photodissociation (90%) Reactions with excited oxygen (10%).

Flux Calculation Barbados (RPB) Ascension (ASC) SAN MAN FLOW Miller et al., 2007 method Trajectories Study (Hysplit model) “A Very Large Flux Chamber”

Back trajectories  Used to calculate time air has been over land at 8 altitudes.  Typically quite similar as a function of altitude.

Calculating the background ‘No’ Emissions 2x10 5 Step 1. Chose SF 6 like a tracer transport

“Santarém” Fluxes WETDRY 2005 Wet season enhancement – probably related to agriculture

“Manaus” Fluxes WETDRY

Summary and Comparison with other estimates Years/SiteSAN MAN WetDryWetDry ± ± ± ± ± ± 0.7 Comparison (mg N 2 O/m-2yr-1) 1.9 – Primary Forest, Rondônia, Brazil (Garcia- Montiel, et al., 2004) 0.38 – Primary Forest, Manaus, Brazil (Coolman, 1994) 0.44 – Young Pasture, Manaus, Brazil (Coolman, 1994)

Conclusions The normalized profiles show a clear enhancement during wet season. SAN fluxes were enhanced until In 2006 political programs decreased the N-fertilizer used in Para. MAN fluxes are lower in 2006 for the same reason. Fluxes calculated are similar other studies over near regions.

Question: What is the Forest Contribution? Barbados (RPB) Ascension (ASC) SAN MAN FLOW Two Methods: 1. Subtracting fluxes 2. Use SAN as the background for MAN 3. Both methods: choose trajectories where air comes from SAN to MAN.

Preliminary Results Profiles considering: same trajectory, close date  Uncertainty is large, but little evidence for large emissions in forest between SAN and MAN.

Conclusions The normalized profiles show a clear enhancement during wet season. SAN fluxes were enhanced until In 2006 political programs decreased the N- fertilizer used in Para. MAN fluxes are lower in 2006 for the same reason. Coast to SAN present higher fluxes than coast to MAN. Fluxes calculated are similar other studies over near regions.
