Scaling laws of passive tracer dispersion in the turbulent surface layer
Scaling laws passive tracer dispersion the turbulent surface layer
2011/8/18
Abstract: Experimental results for passive tracer dispersion in the turbulent surface layer under stable conditions are presented. In this case, the dispersion of tracer particles is determined by the...
Tracer concentration profiles measured in central London as part of the REPARTEE campaign

2010/8/12
Atmospheric transport of traces gases and aerosols plays an important role in the distribution of air pollutants and radiatively active compounds. For model simulations of chemistry-climate interactio...
Grid resolution dependence in the reconstruction of an atmospheric tracer source
Grid resolution dependence reconstruction atmospheric tracer source
2009/11/9
Methods for reconstructing sources of inert atmospheric tracers from ground measurements are currently studied, tested, and even implemented (in accident-type radionuclide release backtracking, for re...
Properties of the average distribution of equatorial Kelvin waves investigated with the GROGRAT ray tracer

2009/11/9
Kelvin waves excited by tropospheric convection are considered to be one of the main drivers of the stratospheric quasi-biennial oscillation (QBO). In this paper we combine several measured data sets ...

We introduce the Coupled Aerosol and Tracer Transport model to the Brazilian developments on the Regional Atmospheric Modeling System (CATT-BRAMS). CATT-BRAMS is an on-line transport model fully consi...
The effects of experimental uncertainty in parameterizing air-sea gas exchange using tracer experiment data
parameterizing air-sea gas tracer
2009/3/12
It is not practical to measure air-sea gas fluxes in the open ocean for all conditions and areas of interest. Therefore, in many cases fluxes are estimated from measurements of air-phase and water-pha...
Uptake of HNO3 to deliquescent sea-salt particles: a study using the short-lived radioactive isotope tracer 13N

2009/3/12
The uptake of HNO3 to deliquescent airborne sea-salt particles (RH = 55%, P = 760 torr, T = 300 K) at concentrations from 2 to 575 ppbv is measured in an aerosol flow tube using 13N as a tracer. Small...
