The links between air pollution gas phase chem., aerosol chem. processes, and solar radiation are calcd. to improve air quality models. Air quality models are used to simulate pollutant content of the city plumes such as for Los Angeles. ...
Regional budgets of pollutants in the atmospheric boundary layer (ABL) provide valuable information on transport and chemical processes, especially over complex terrain where local assessments are not representative. Horizontal transport, vertical transpor ...
Compact holographic memory architecture with phase conjugate readout and diffraction suppression by internal reflection is investigated. The pixel size requirement for a competitive system is determined. The bandwidth of the holographic recording in LiNbO3 ...

An episode selection procedure was developed and applied to select sets of days representing characteristic meteorol. conditions leading to high ozone episodes over the Swiss Plateau. The selection procedure was applied to data extending from Jan. 1991 thr ...
We have improved the sensitivity and signal-to-noise ratio of a luminescence upconversion experiment, using a charge-coupled device (CCD) as the detector. We show experimentally and numerically that the bandwidth of a 1-mm-thick beta-barium berate crystal ...
The LIDAR principle for air quality and meteorol. measurements is presented, followed by different examples of vertical O3 profiles and time series obtained with a new optical layout of the EPFL-LPAS DIAL system using dual telescope detection. These data w ...
A de-trending technique was developed for short-term and annual variations to identify long-term trends in primary and secondary pollutants. With this approach, seasonal and annual variations are removed using a mean year; the residual meteorol. short-term ...
