| description | <p>The NASA North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) ship
and aircraft field campaign deployed to the western subarctic Atlantic
between the years 2015 and 2018. One of the primary goals of NAAMES is to
improve the understanding of aerosol–cloud interaction (ACI) over the
Atlantic Ocean under different seasonal regimes. ACIs currently represent the
largest source of uncertainty in global climate models. During three NAAMES
field campaigns (NAAMES-1 in November 2015, NAAMES-2 in May 2016, and
NAAMES-3 in September 2017), multiple 10 h science flights were conducted
using the NASA C-130 aircraft to measure marine boundary layer aerosol and
cloud properties. The standard flight pattern includes vertical spirals
where the C-130 transitioned from high altitude to low altitude (and vice
versa), collecting in situ measurements of aerosols, trace gases, clouds, and
meteorological parameters as a function of altitude. We examine the data
collected from 37 spirals during the three NAAMES field campaigns, and we
present a comprehensive characterization of the vertical profiles of aerosol
properties under different synoptic conditions and aerosol regimes. The
vertical distribution of submicron aerosol particles exhibited strong
seasonal variation, as well as elevated intra-seasonal variability depending
on emission sources and aerosol processes in the atmospheric column.
Pristine marine conditions and new particle formation were prevalent in the
wintertime (NAAMES-1) due to low biogenic emissions from the surface ocean
and reduced continental influence. Higher concentrations of submicron
aerosol particles were observed in the spring (NAAMES-2) due to strong
phytoplankton activity and the arrival of long-range-transported continental
plumes in the free troposphere with subsequent entrainment into the marine
boundary layer. Biomass burning from boreal wildfires was the main source of
aerosol particles in the region during the late summer (NAAMES-3) in both
the marine boundary layer and free troposphere.</p> |
