Dear Ramon,
you concept seems problematic, because of the chloride and even bromide
content of sea salt. The troposphere contains acids like HNO3 and H2SO4.
These acids will generate HCl and HBr from the sea salt particles as we
know from tropospheric sea salt particles. Oxidants like O3 or radicals
like °OH will generate ozone depleting chlorine and bromine spezies like
atomic °Cl and °Br and their oxides. Within short time these species
would have depleted the tropospheric ozone layer.
Further your proposal has the disadvantage of all SRM measures: Their
operation is only able to cool the temperature at the planets surface -
but they are not able to do anything to deplete the cause of the climate
warming: the greenhouse gases increase.

Betreff: [geo] geoengineering by albedo modification
Hello, i hope you accept me in your group!!! I have been interested in
this topic both the potential as well as the concerns. I also read the
report from the NRC on this topic and found it excellent, balanced and
with good follow up recommendations.My colleague Jimmy Peress and i
have considered the option of using sodium cloride particles as the
reflecting particles. Specifically spraying in the upper atmosphere
concentrated sea watert(25% sea salt in water) that, due to
sublimation, should yield very small sodium chloride particles.
Attached is a short report on what we propose..We look forward to hear
your comments and, if you think is worth pursuing, suggest research
groups that may want to find out if the concept is worth pursuing
