Atmospheric Black Carbon over Qatar: Seasonal Variability and Source Apportionment
( Qatar University Press , 2021 , Poster)The earth’s atmosphere contains minute particles suspended within it. These atmospheric particles influence the earth's radiation budget through their ability to absorb and scatter radiation. Black carbon (BC) is a type ... -
Bryophyte cover and richness decline after 18 years of experimental warming in alpine Sweden.
( Oxford University Press , 2020 , Article)Climate change is expected to affect alpine and Arctic tundra communities. Most previous long-term studies have focused on impacts on vascular plants, this study examined impacts of long-term warming on bryophyte communities. ... -
BTEX, nitrogen oxides, ammonia and ozone concentrations at traffic influenced and background urban sites in an arid environment
( Elsevier , 2019 , Article)Spatial distribution of key air pollutants were studied in Doha, Qatar, over the course of two monitoring campaigns in early spring, 2016. Time-weighted averages of BTEX components (benzene, toluene, ethyl-benzene, ... -
Do changes in current flow as a result of arrays of tidal turbines have an effect on benthic communities?
( Public Library of Science , 2016 , Article)Arrays of tidal energy converters have the potential to provide clean renewable energy for future generations. Benthic communities may, however, be affected by changes in current speeds resulting from arrays of tidal ... -
Edms model verification considering remarkable changes in airport traffic system
