An episode of extremely high PM concentrations over Central Europe

An episode of extremely high PM concentrations over Central Europe caused by dust emitted over the southern Ukraine

Elevated PM10 and PM2.5 concentrations in Europe: a model experiment with MM5-CMAQ and WRF-CHEM

We have applied the MM5-CMAQ model to simulate the high concentrations in PM10 and PM2.5 during a winter episode (2003) in Central Europe. The selected period is January 15 – April 6 2003. Values of daily mean concentrations up to 75 μgm are found on average of several monitoring stations in Northern Germany. This model evaluation shows that there is an increasing underestimation of primary and...

Ancient Schwannoma of the Trigeminal Nerve Mimicking High Grade Lesion

  Ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. A seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. Imaging findings were suggestive of left temporal high grade lesion. During surgery there was well...

Interannual variation and trends in air pollution over Europe due to climate variability during 1958–2001 simulated with a regional CTM coupled to the ERA40 reanalysis

A three-dimensional Chemistry Transport Model was used to study the meteorologically induced interannual variability and trends in deposition of sulphur and nitrogen as well as concentrations of surface ozone (O3), nitrogen dioxide (NO2) and particulate matter (PM) and its constituents over Europe during 1958–2001. The model was coupled to the meteorological reanalysis ERA40, produced at the Eu...

بررسی شرایط تخلیه جت دایره‌ای همسو در منابع آب پذیرنده بی‌نهایت کم عمق

Discharge of contaminants in the acceptor ambient has negative environmental impacts. Extremely shallow acceptor ambient conditions will have a significant impact on the diffusion of the contaminants flow. To achieve the effect of the hydraulic, geometric and environmental conditions of the contaminant flow in the acceptor ambient, an experimental model of surface draining was applied. The mode...
