Observing Contrails (A Trifle Complicated)
This post describes the ways we can observe and measure contrails to evaluate contrail forecast models and improve our understanding of contrail effects.

The Cost of Contrail Management
This post presents an order-of-magnitude estimate for the long-term cost-benefit of navigational contrail avoidance. At the end, we've built an interactive tool to explore the sensitivity of abatement cost to assumptions.
