Undergraduate Research at
Scripps: Patrick Ferree: In the Spring of 2012 Patrick atomized motor oil onto Teflon filters and scanned them to obtain FTIR spectra. A summary of his project along with his findings can be found here: Patrick's Motor Oil Analysis.
Undergraduate Research at
CalNex:Becca Rolph: At the
Caltech site in Pasadena, Becca helped set up the air pump used to
collect the samples, and also prepared the filters that were used in the
sample collection. Once the air pump was set up, Jason Surratt changed
the filters at Caltech and recorded how long each filter was sampling.
The filters were then frozen and sent back to SIO overnight, where
Becca analyzed them with FTIR spectroscopy to obtain the sample spectra.
The samples were frozen and the spectra were obtained in a timely
manner to prevent loss of organonitrates, which may degrade over time.
Now that the spectra have been obtained, we are using an algorithm to
peakfit and integrate the spectra to determine the functional groups
present in the samples.
Undergraduate Research
at CalMex:Anita Johnson:
In preparing to go to the Tijuana site, Anita scanned
Teflon filters to obtain their background FTIR spectra. On site and
back at Scripps, she analyzed each filter's time series and re-scanned
the samples to obtain mass, concentration, and mole data for alcohols,
alkanes, carbonyls, amines, and acids based on the functional group
abundance in each spectrum. These will be compared with data from the
ACSM to give the most accurate picture of organic components in the
sampled aerosols.
Graduate Research at VOCAL S-REx 2008:Lelia
Hawkins: Earlier this year graduate student Lelia
Hawkins of the Russell Group went on board the NOAA Research Vehicle
Ronald Brown
measuring atmospheric aerosol particles like dust,
soot, organics, sulfate, nitrate and sea salt. Her experience was an
excellent
example of the first-hand work done in the field
that contribute to our understanding of atmospheric aerosols. Her
introduction, as well as 3 postcards are available here:
Undergraduate and Graduate Research at Whistler, BC:Rachel Schwartz: Organic
aerosol measurements have been made at Whistler, Britsh Colubmia in
spring of 2008 and spring to summer of 2009. From the 2008 measurements
we have identified
biogenic influences on the aerosol and have provided a biogenic
functional group characterization. Preliminary results from the 2009
measurements show the influence of biogenic, long range transport,
and biomass burning sources on the measured aerosol. We propose to
collect bulk and single particle measurements at mid mountain and peak
sites to assess the impact of these particles on cloud formation
processes in spring 2010.
