The UK is one of several countries around the world that has enacted legislation to reduce its greenhouse gas emissions. In this study, we present top-down emissions of methane (CH4) and nitrous oxide (N2O) for the UK and Ireland over the period Augu

Can seasonal and interannual variation in landscape CO2 fluxes be detected by atmospheric observations of CO2 concentrations made at a tall tower?

Autor: T. L. Smallman, M. Williams, J. B. Moncrieff

Publikováno v: Biogeosciences, Vol 11, Iss 3, Pp 735-747 (2014)

The coupled numerical weather model WRF-SPA (Weather Research and Forecasting model and Soil-Plant-Atmosphere model) has been used to investigate a 3 yr time series of observed atmospheric CO2 concentrations from a tall tower in Scotland, UK. Ecosyst

WRFv3.2-SPAv2: development and validation of a coupled ecosystem–atmosphere model, scaling from surface fluxes of CO2 and energy to atmospheric profiles

Autor: T. L. Smallman, J. B. Moncrieff, M. Williams

Publikováno v: Geoscientific Model Development, Vol 6, Iss 4, Pp 1079-1093 (2013)

The Weather Research and Forecasting meteorological (WRF) model has been coupled to the Soil–Plant–Atmosphere (SPA) terrestrial ecosystem model, to produce WRF-SPA. SPA generates realistic land–atmosphere exchanges through fully coupled hydrolo

Scaling properties of velocity and temperature spectra above the surface friction layer in a convective atmospheric boundary layer

Autor: K. G. McNaughton, R. J. Clement, J. B. Moncrieff

Publikováno v: Nonlinear Processes in Geophysics, Vol 14, Iss 3, Pp 257-271 (2007)

We report velocity and temperature spectra measured at nine levels from 1.42 meters up to 25.7 m over a smooth playa in Western Utah. Data are from highly convective conditions when the magnitude of the Obukhov length (our proxy for the depth of the
