Large sulfur dioxide plumes were measured in the Mexico City Metropolitan Area (MCMA) during the MILAGRO field campaign. This paper seeks to identify the sources of these plumes and the meteorological...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data

The snow cover is an important parameter for water run-off prediction in high
mountain areas. At present its seasonal changes can be monitored regularly by
satellite. The paper presents a new method...
Multi-species inversion of CH4, CO and H2 emissions from surface measurements
Multi-species CH4 CO H2 emissions surface measurements

2009/8/7
In order to study the spatial and temporal variations of the emissions of greenhouse gases and of their precursors, we developed a data assimilation system and applied it to infer emissions of CH4, CO...
Validation of urban NO2 concentrations and their diurnal and seasonal variations observed from the SCIAMACHY and OMI sensors using in situ surface measurements in Israeli cities

2009/2/6
Near-surface water velocities have been measured in the coastal zone of Lake Huron and Cape Cod Bay by tracking drifters and drogues using acoustic travel time and compass sighting techniques. The nea...
