Jim Lee Interviews Head of FAA/NASA Climate Change Research

3/28/2017 -  From Jim Lee:

I will be interviewing the head of the FAA/NASA Aviation Climate Change Research Initiative (ACCRI), who is also the head of the ACCESS test flights, possibly this week!  Heads are going to roll!

Dr. Halthore,

Thank you for that excellent conversation on the phone earlier. Here are the references we will be discussing.  I hope we can set up a Google Hangout (like Skype) interview this week sometime if possible.

Thank you so much for the opportunity.

FSC QUOTES
 
“Use commuter aircraft fuels doped with aerosol generators”

http://youtu.be/o3rAZ8Fmc0Q?t=15m50s

“dissolved or suspended in their jet fuel and later burned with the fuel to create seeding aerosol, or (2) injected into the hot engine exhaust, which should vaporize the seeding material, allowing it to condense as aerosol in the jet contrail”

http://iopscience.iop.org/1748-9326/4/4/045102/pdf/1748-9326_4_4_045102.pdf

“Options for dispersing gases from planes include the addition of sulfur to the fuel, which would release the aerosol through the exhaust system of the plane, or the attachment of a nozzle to release the sulfur from its own tank within the plane, which would be the better option.”

http://climate.envsci.rutgers.edu/pdf/GRLreview2.pdf

“The particles may be seeded by dispersal from seeding aircraft; one exemplary technique may be via the jet fuel as suggested by prior work regarding the metallic particles. Once the tiny particles have been dispersed into the atmosphere, the particles may remain in suspension for up to one year.”

http://www.freepatentsonline.com/5003186.html

A potential delivery mechanism for the seeding material is already in place: the airline industry. Since seeding aerosol residence times in the troposphere are relatively short, the climate might return to its normal state within months after stopping the geoengineering experiment. The main known drawback to this approach is that it would not stop ocean acidification. It does not have many of the drawbacks that stratospheric injection of sulfur species has.

http://iopscience.iop.org/1748-9326/4/4/045102

“Direct detection of total sulfuric acid (SA) has been achieved for the first time in the plume of a jet aircraft in flight. The measurements show the same SA signatures for the case when SA was injected directly into the exhaust jet and the case when sulfur was provided to the engine with the fuel.”

http://onlinelibrary.wiley.com/doi/10.1029/98GL00512/pdf

“Applying high FSCs [fuel sulfur content] at aviation cruise altitudes combined with ULSJ [ultra-low sulfur jet fuel, aviation biofuel] fuel at lower altitudes result in reduced aviation-induced mortality and increased negative RE compared to the baseline aviation scenario.”
