Multiscale estimates of N2O emissions from agricultural lands
Autor: Ramesh Srinivasan, Ward Smith, Devon E. Worth, Matthias Mauder, Brian Grant, Raymond L. Desjardins, J.I. MacPherson, Elizabeth Pattey
Publikováno v: Agricultural and Forest Meteorology. 150:817-824
Nitrous oxide (N2O) emissions are a large proportion of the agriculture sector's contribution to the greenhouse gas inventory of most developed countries. The spatial and temporal variability of N2O emissions from agricultural soils has long been con

Tools for quantifying N2O emissions from agroecosystems
Autor: Dan Pennock, Elizabeth Pattey, Grant C. Edwards, Raymond L. Desjardins, Ward Smith, J.I. MacPherson, Brian Grant
Publikováno v: Agricultural and Forest Meteorology. 142:103-119
The importance of constraining the global budget of nitrous oxide (N 2 O) has been well established. The current global estimate of the contribution of N 2 O to total anthropogenic greenhouse gas emissions from agriculture is about 69%. Considerable

Publikováno v: Geochemistry: Exploration, Environment, Analysis. 6:111-120
National and international concern about the health effects and continued use of Pb, Cd, As and Hg as well as other metals has defined a need for improved estimates of the long-term risks to ecosystems and human health from metals released from minin

Application of a tunable diode laser to the measurement of CH4 and N2O fluxes from field to landscape scale using several micrometeorological techniques
Autor: Grant C. Edwards, Ian B. Strachan, J.I. MacPherson, D. Dow, Raymond L. Desjardins, Elizabeth Pattey
Publikováno v: Agricultural and Forest Meteorology. 136:222-236
Methane and nitrous oxide fluxes were measured at the field to landscape scale by combining tunable diode laser (TDL) technology with micrometeorological techniques. The three following micrometeorological measurement platform were used: (1) tower-ba

BOREAS flight measurements of forest-fire effects on carbon dioxide and energy fluxes
Autor: Brian D. Amiro, Raymond L. Desjardins, J.I. MacPherson
Publikováno v: Agricultural and Forest Meteorology. 96:199-208
Fire is the dominant stand-replacing agent in the Canadian boreal forest, but few quantitative measurements are available on the micrometeorological effects of fire. Airborne flux measurements during the BOREAS experiment were referenced to age of bu

Publikováno v: Atmospheric Environment. 29:3115-3132
The California Ozone Deposition Experiment (CODE) is a program of observations and modeling to improve estimates of the rate of removal of tropospheric ozone at the earth's surface used in grid-based photochemical models of ozone production, transpor
