MAG/AOS/ALL/M1/S1/S2 - Ship in port
DataStreams:magaoso3M1.a1
Description:
The ship was in port during these periods and the measurements may be affected by various 
sources (overhead cranes, anthropogenic sources, etc).

Note: Dates and times were found by looking at the NAV datastream.  The standard deviation 
of pitch, roll, and surge velocity were used to determine when the ship was slowing down 
to enter port or speeding up to leave port.  Thresholds used; pitch (0.01), roll (0.01), 
surge velocity (3.0)

  • ozone_pressure
  • base_time
  • ozone_bench_temp
  • time
  • East longitude(lon)

MAO/AOS/M1/S1 - Forest Fire
DataStreams:maoaoso3S1.a1
Description:
Smoke from forest burning can be seen on the TSI images rising and then subsequently 
moving over the site during this period.  Many of the AOS instruments observed a sharp spike 
in data values.

October 4-8 multiple fires in the area resulted in hazy conditions during this entire 
period.

Most notable in the following instruments and variables

ACSM - Total Organics
AETH - Black Carbon Concentrations at all wavelengths
CCN100 - Spike in number concentrations occurred a few hours after the smoke plume
CLAP3W - Absorption Coefficient
CPC - Similar to the CCN100, spike in particle concentration occurred a few hours later
CPCF - Particle Concentration
CPCU - Particle Concentration
NEPHELOMETERS - Scattering/Backscattering Coeff
PSAP3W - Absorption Coefficient
SMPS - Concentration and Size Distribution
UHSAS - Size Distribution

OLI/OZONE/M1 - Calibration varied unexpectedly
DataStreams:oliaoso3M1.a1
Description:
The calibration response showed a decrease and then recovered.  The decrease was about 
10%.  It is not clear what this was due to.  The instrument sensitivity COULD have varied by 
the same amount, but this isn't clear.  AMF3 AOS experienced temperature swings during 
this period that may have affected the O3 standard or the O3 photometer or both.  Given 
the low ambient concentrations, a 10% reduction in response would be almost indetectable, 
hence the transparent categorization.
