I know that you would normally not consider attending an advanced graduate course on atmospheric chemistry, but this quarter you may want to reconsider, since the topic covered in my class will only partly relate to chemistry. I want to try out a new class that concentrates on the various aspects of aerosol microphysics and chemistry as they relate to global climate questions. The announcement is attached and can also be read under http://www.atmos.ucla.edu/~jochen/courses/AS230.html.
The motivation for offering the class is three-fold:
1) This is one of today’s most active research topics of the atmospheric sciences.
2) For those of you that did not have a chance to attend AS203B (Aerosol and Cloud Microphysics), this class offers an opportunity to learn some of the things reviewed in this class, with a little less depth but in a more interesting context. (For those of you that did attend, this is a good review).
3) It is a really cool topic which requires the combination of different aspects of atmospheric sciences, i.e. radiation, physics, chemistry, modeling etc.
The class will be mostly based on papers / review articles / book chapters, and the discussion of those in class. Attached is a tentative syllabus, which can and will be changed as we go along in the class. I put a review paper and two of the original articles on indirect aerosol effects on my web-page (http://www.atmos.ucla.edu/~jochen/courses/downloads/)

I am offering a special 281 Seminar this coming quarter. The title
is
"July 2001 at 120W, 30N"
The idea is for us to write a paper evaluating the conditions at about
this point as observed during the DYCOMS field study as compared to climatology
and satellite retrievals. The motivation for the class was my realization
that the paper needs to be written, but that I won't write this paper by
myself. Moreover, many of you are using satellite data products for
which the in situ observations at this place (a region of persistent stratocumulus)
could provide valuable constraints. Because there
is great interest in using such retrievals, and reanalysis products in data
sparse, but climatologically important regions such as this, the insights
we hope to gleam from such a study could prove quite valuable.
Regarding organization, we will meet once a week for approximately 90 minutes.
The time and place of our regular meetings will be determined at our first
meeting (provisionally scheduled for Tuesday at 11:30 on the first full week
of classes). Enrollment is with permission of the instructor --- probably
everyone should sign up for two credits. What I am looking for
is students who have a satellite data product, reanalysis data product,
or some strong motivation and who are interested in joining this effort.
Ideally these should be things you are familiar with and currently working
on, as the point of this class is to build on everyone's ongoing research,
not detract from it. I envision each person
producing one or two figures for the paper we are writing, and maybe a page
of accompanying text.
Assuming we arrive at our goal (a paper) co-author status will be
offered to those who make contributions. If I have not
yet spoken to you about this class, and are interested, but are unsure how
you can contribute, feel free to contact me.
Cheers, Bjorn
The class will focus on moist atmospheric convection. A rough outline is as follows:
1) Introduction (one week)
a) moist thermodynamics
b) convective regimes
2) Stratocumulus Convection (three weeks)
a) mixed layer theory
b) cloud transitions
c) role of precipitation
3) Trade Cumulus Convection (three weeks)
a) bulk theory
b) mass flux theory
c) the role of precipitation
4) Deep Precipitating Convection (three weeks)
a) The adjustment problem
b) Radiative Convective Equilibrium
c) Coherent Structures
d) Parameterization
