Seasonal and diurnal variations of PM_(2.5) mass concentration formation and accumulation within these areas have been analyzed. Air quality monitoring data and meteorological data (both QA/QCed) were obtained from Federal and Provincial Pakistan Environmental Protection Agencies. In Islamabad, the annual average PM_(2.5) mass concentrations were 81.1 ± 48.4 μg/m^3, 93.0 ± 49.9 μg/m^3, 47.8 ± 33.2 μg/m^3, 79.0 ± 49.2 μg/m^3, and 66.1 ± 52.1 μg/m^3 during 2007 to 2011 respectively. Comparison of the four cities during summer 2007 to spring 2008 shows that all the four cities had PM_(2.5) concentration exceeding the Pakistan National Environmental Quality Standards (annual average concentration of 25 μg/m^3; and 24 hourly average concentration of 40 μg/m^3) for ambient air. During the same time period, the highest seasonal PM_(2.5) mass concentrations for Islamabad were observed as 98.5 μg/m^3 during spring 2008; 150.4 ± 87.9 μg/m^3; 104.1 ± 51.1 μg/m^3 and 72.7 ± 55.2 μg/m^3 for Lahore, Peshawar, and Quetta during fall 2007, respectively. Wind speed and temperature have a negative correlation with the mass concentration of PM_(2.5). Diurnal profile for all the cities suggests an association of PM_(2.5) with vehicular traffic. Back trajectory analysis conducted using the NOAA HYSPLIT model indicates that air trajectories, during high pollution episodes, influencing the urban regions commonly originate from either western India, especially in summer as part of the prevailing monsoon circulation; or are located in eastern Afghanistan. The source areas in Western India i.e., states of Gujarat, Rajasthan and Punjab have high concentration of industrial activities and crop residue burning, and are likely sources of enhanced PM_(2.5) concentrations, in addition to the local sources.}, number={2}, journal={AEROSOL AND AIR QUALITY RESEARCH}, author={Rasheed, Anjum and Aneja, Viney P. and Aiyyer, Anantha and Rafique, Uzaira}, year={2015}, month={Apr}, pages={426–439} } @article{aiyyer_2015, title={Recurving western North Pacific tropical cyclones and midlatitude predictability}, volume={42}, ISSN={["1944-8007"]}, DOI={10.1002/2015gl065082}, abstractNote={Abstract}, number={18}, journal={GEOPHYSICAL RESEARCH LETTERS}, author={Aiyyer, A.}, year={2015}, month={Sep}, pages={7799–7807} } @article{rasheed_aneja_aiyyer_rafique_2014, title={Measurements and analysis of air quality in Islamabad, Pakistan}, volume={2}, ISSN={2328-4277}, url={http://dx.doi.org/10.1002/2013EF000174}, DOI={10.1002/2013EF000174}, abstractNote={Abstract}, number={6}, journal={Earth's Future}, publisher={American Geophysical Union (AGU)}, author={Rasheed, Anjum and Aneja, Viney P. and Aiyyer, Anantha and Rafique, Uzaira}, year={2014}, month={Jun}, pages={303–314} } @article{mallard_lackmann_aiyyer_hill_2013, title={Atlantic Hurricanes and Climate Change.

The aerosol-cloud interaction in different parts of the globe is examined here using multi-year statistics of remotely sensed data from two MODIS sensors aboard NASA's Terra (morning) and Aqua (afternoon) satellites. Simultaneous retrievals of aerosol loadings and cloud properties by the MODIS sensor allowed us to explore morning-to-afternoon variation of liquid cloud fraction (CF) and optical thickness (COT) for clean, moderately polluted and heavily polluted clouds in different seasons. Data analysis for seven-years of MODIS retrievals revealed strong temporal and spatial patterns in morning-to-afternoon variation of cloud fraction and optical thickness over different parts of the global oceans and the land. For the vast areas of stratocumulus cloud regions, the data shows that the days with elevated aerosol abundance were also associated with enhanced afternoon reduction of CF and COT pointing to the possible reduction of the indirect climate forcing. A positive correlation between aerosol optical depth and morning-to-afternoon variation of trade wind cumulus cloud cover was also found over the northern Indian Ocean, though no clear relationship between the concentration of Indo-Asian haze and morning-to-afternoon variation of COT was established. Over the Amazon region during wet conditions, aerosols are associated with an enhanced convective process in which morning shallow warm clouds are organized into afternoon deep convection with greater ice cloud coverage. Analysis presented here demonstrates that the new technique for exploring morning-to-afternoon variability in cloud properties by using the differences in data products from the two daily MODIS overpasses is capable of capturing some of the major features of diurnal variations in cloud properties and can be used for better understanding of aerosol radiative effects. }, number={10}, journal={Atmospheric Chemistry and Physics}, author={Meskhidze, N. and Remer, L.
