Description:
Scatterometer data from Seasat, until the mission abruptly ended in October 1978, was used to derive 10-meter wind speed components over the global ocean at 2.5-degree resolution. These winds were then used to compute surface stress using the Large and Pond formulation for the drag coefficient, assuming neutral stability.

Description:
Goals:
To calculate SOA yield from Cl-initiated photooxidation of isoprene at a VOC:Cl2 ratio of 0.45, and using neutral seed.
Summary:
Neutral seed was injected with an initial seed surface area of 900 um2/cm3, followed by a Cl2 injection out of a gas cylinder, and the isoprene injection using a heated glass bulb. Temperature was kept at 25C for the whole duration of the experiment, while RH was kept at less than 10%.
