- Using the material
in Chapter 8 and texts from the Further Reading list, summarize
the various causes of movement in the atmosphere.
- The Carbon Dioxide
Research Group at Scripps Institution of Oceanography
publishes a long-term dataset of monitored concentrations of carbon
dioxide in
the atmosphere (http://cdiac.esd.ornl.gov/trends/co2/sio-mlo.htm).
Download
their dataset and use it to chart the change in annual mean concentration
of carbon dioxide since 1958.
Remember to include the units of concentration on your graph.
Describe the trend
in carbon dioxide concentrations that your graph shows and discuss
the implications
of this for the global atmosphere.
- What are emissions
inventories and why are they important?
- Access the article
by Allen Lefohn, Janja Husar and Rudolf Husar called
‘Estimating Historical Anthropogenic Global Sulfur Emission
Patterns for the
Period 1850–1990’ (published
in Atmospheric Environment 33 (1999)
3435–3444 and available on the internet at
http://capita.wustl.edu/CAPITA/CapitaReports/GlobSEmissions/GlobS1850_1990.htm).
Use the information from this paper and from Chapter 8 to answer
the following questions:
(a) Why is sulphur dioxide important?
(b) What are the global trends in
sulphur dioxide emissions?
(c) What are the relative contributions
from different countries and different sources?
(d) What uncertainties are there
in estimating emissions of sulphur dioxide?
- What are the most
pressing urban air quality issues in your country?
Carry out a review of literature sources and websites to help
you
(hint: your local authority and
national government websites would be a good
place to start).
