Eddy covariance measurements and parameterisation of traffic related particle emissions in an urban environment
Urban aerosol sources are important due to the health effects of particles and their potential impact on climate. Our aim has been to quantify and parameterise the urban aerosol source number flux F (particles m−2 s−1), in order to help improve how this source is represented in air quality and climate models. We applied an aerosol eddy covariance flux system 118.0 m above the city of Stockholm....
متن کاملEddy Covariance Measurements over Grasslands
In this chapter we first provide a historic overview of – and outline some of the peculiarities associated with – grassland eddy covariance flux measurements, elaborate on the additional terms that need to be quantified when estimating the grassland net ecosystem carbon balance and finally discuss some of the challenges associated with upcoming nitrous oxide and methane flux measurements in man...
متن کاملDaytime CO 2 urban surface fluxes from airborne measurements , eddy - covariance observations and 1 emissions inventory in Greater London 2
11 Airborne measurements within the urban mixing layer (360 m) over Greater London are used to quantify CO2 12 emissions at the meso-scale. Daytime CO2 fluxes, calculated by the Integrative Mass Boundary Layer (IMBL) 13 method, ranged from 46 to 104 μmol CO2 m -2 s -1 for four days in October 2011. The day-to-day variability of 14 IMBL fluxes is at the same order of magnitude as for surface edd...

متن کاملNitrous oxide emissions from managed grassland: a comparison of eddy covariance and static chamber measurements
Managed grasslands are known to be an important source of N2O with estimated global losses of 2.5 Tg N2ON yr−1. Chambers are to date the most widely used method to measure N2O fluxes, but also micrometeorological methods are successfully applied. In this paper we present a comparison of N2O fluxes measured by non-steady state chambers and eddy covariance (EC) (using an ultra-sonic anemometer co...
