EAD air quality monitoring network. Site survay for 10 new stations. NILU OR
Recommendations for additional monitoring stations in Abu Dhabi have been based on monitoring criteria and the objectives for measurements. It has been stressed that measurements have to be performed based on a number of permanent air quality stations. Also the meteorological measurements have to be co-ordinated with the permanent stations.
Based on the evaluations performed in Abu Dhabi, we have proposed three sites which should be developed and started immediately (1-3). Another three areas have been indicated for future and further evaluations. However, we believe that there will be a need in the near future also for measurements in these areas.

Eastward-propagating planetary waves prior to the January 2009 sudden stratospheric warming
Eastward-propagating planetary waves (EPWs) were investigated prior to the boreal January 2009 major sudden stratospheric warming (SSW) event simulated by the National Center for Atmospheric Research's Whole Atmosphere Community Climate Model with specified dynamics. About 22 days before SSW onset, a background flow with jet maxima around the upper polar stratosphere and subtropical mesosphere developed due to the net forcing by gravity and planetary waves. The mesospheric wind structure was largely unstable and supported a wave geometry conducive to overreflection. With a zonal phase speed of ∼10 m s−1, EPWs appeared near their turning and critical layers as wavenumber-2 perturbations in the stratosphere and mesosphere. Accompanied by upward EPW activity from the lower stratosphere, EPW growth exhibited characteristics of wave instability and overreflection.
