A case study of the effects of ship emissions on the microphysical, radiative, and chemical properties of polluted marine boundary layer clouds is presented. Two ship tracks are discussed in detail. <i>In situ</i> measurements of cloud drop size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside-cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to remotely sensed measurements of cloud radiative properties. The authors examine the processes behind ship track formation in a polluted marine boundary layer as an example of the effects of anthropogenic particulate pollution on the albedo of marine stratiform clouds. |

The Asian Development Bank has sponsored research on market-based instruments for managing pollution in Metro Manila, Philippines, where air quality is seriously degraded. This report offers three policy options for reducing particulate emissions and their precursors. For stationary sources, we recommend an emissions fee that creates efficient financial incentives to reduce emissions while raising revenues for monitoring and enforcement activities. For mobile sources, we propose a pilot diesel retrofit program using a low-cost technology that is effective at existing 2,000 ppm sulfur content. Second, we recommend a charge on the sulfur content of diesel fuel to encourage meeting and surpassing the 500 ppm standard to allow for more advanced particulate... |
