We are seeking data and charts which show the evaporation of gasoline
from above ground, floating-lid storage tanks based on average daily
temperature.

Are you familiar with the AP42 emission factor guidelines?

They are designed to accurately estimate tank emissions based on a
wide-variety of factors, including temperature and the material
stored, along with vent configuration, tank color, climate conditions,
and so on.

The calculations are complex, but AP42 is the industry and regulatory
standard for calculating emissions.

Here are the standards as applied to petroleum-storage tanks:

AP-42, CH 7.1: Organic Liquid Storage Tanks


Let me know if that helps, or if it's way more than you really wanted to know!
