Estimating the maritime component of aerosol optical depth and its dependency on surface wind speed using satellite data
the maritime component aerosol optical depth surface wind speed satellite data
2010/8/16
Six years (2003–2008) of satellite measurements of aerosol parameters from the Moderate Resolution Imaging Spectroradiometer (MODIS) and surface wind speeds from Quick Scatterometer (QuikSCAT), the Ad...
Relationship between wind speed and aerosol optical depth over remote ocean
wind speed aerosol optical depth remote ocean
2010/8/13
The effect of wind speed on aerosol optical depth (AOD) at 0.55 μm over remote ocean regions is investigated. Remote ocean regions are defined by the combination of AOD from satellite observation and ...
Uncertainties in wind speed dependent CO2 transfer velocities due to airflow distortion at anemometer sites on ships
wind speed dependent CO2 velocities airflow distortion anemometer sites ships
2010/8/13
Data from platforms, research vessels and merchant ships are used to estimate ocean CO2 uptake via parameterisations of the gas transfer velocity (k) and measurements of the difference between the par...
Sensitivity of ensemble Lagrangian reconstructions to assimilated wind time step resolution
ensemble Lagrangian reconstructions wind time step resolution
2010/8/12
We study the impact of temporal and spatial resolution and changes in modelled meteorological winds in the context of diffusive ensemble Lagrangian reconstructions. In situ tracer measurements are mod...
