Meetings
Dear
Colleagues, please consider submitting an abstract to the EGU General Assembly
2012 session
PS1.2/AS4.21/ST6.1
POLARIMETRY AS AN INVALUABLE TOOL TO STUDY
THE SOLAR SYSTEM AND BEYOND.
http://meetingorganizer.copernicus.org/EGU2012/session/10059
Polarimetry is a powerful diagnostic tool providing a
wealth of information about objects from the Earth atmosphere to the far
universe that cannot be obtained by traditional photometric/spectroscopic
observations. In the solar system
polarimetry has been widely used
e.g. to characterize the surface of atmosphereless
bodies, dust and aerosols in planetary atmospheres, or to explore the magnetism
of the solar atmosphere. This session is open to papers about recent polarimetric observations of solar system bodies including
the Earth and the sun, theoretical or experimental
investigations and instrumental developments for polarimeters to be included in ground-based facilities or
onboard future space missions. Contributions about detection and/or
characterization of exoplanets with polarimetry are also welcome.
Deadline
for submission of abstracts: 17 January 2012
http://meetings.copernicus.org/egu2012/abstract_management/how_to_submit_an_abstract.html
Deadline
for submission of support application : 15 December
2011
http://meetings.copernicus.org/egu2012/support_and_distinction/financial_support.html
This
initiative is not directly related to COST. However, we would really like to
install this session in the long-term at EGU. Hence, this is important to
receive as many abstracts as possible since if we do not have around 20
abstracts, the
session might eventually end as a poster session only.
Thank
you for your help!

regards,

CPS 9TH INTERNATIONAL SCHOOL OF PLANETARY SCIENCES
Registration
is now open for the upcoming school.
Objective
and Scope: The objective of the school is to promote education and research in
planetary sciences for highly motivated graduate students and young researchers
by providing them with an opportunity to interact with leading scientists in a
specific field. Note that the term Planetary Sciences broader sense to include
astronomy, astrophysics, astrochemistry, astrobiology,
astromineralogy, geosciences, space science,
cosmology, and other related fields.
The
topic of the coming school: Across the Earth into Exoplanets
The
first circular and the detailed information are now available at the CPS Web
site:

Dear ELS XIII participants,
We have finally uploaded a selection
of pictures taken during ELS XIII in the conference web site. So, if you want
to have a look, just visit http://elsxiii.unime.it/
We remind you that, starting from
November the 14th, and until January the 16th, 2012, the submission procedure
to the JQSRT special issue for ELS XIII will be open.
Should you need any help or further
information, please do not hesitate to contact me and my colleagues.
King regards, Rosalba

ADDA update
We have recently discovered a bug in
ADDA 1.0 that may affect the simulations involving Gaussian beams. The value of
Cext that is produced by ADDA is computed by the same
formula as for the plane incident wave (i.e. exactly as specified in the
manual). The problem is that this formula is not adequate for the Gaussian
beams, i.e. it does not describe the Cext, which is
defined through the energy balance (in particular, for non-absorbing particles
obtained value of Cext is not equal to Cabs). So
currently please discard the ADDA result for Cext
when simulating Gaussian beams.
There exist a simple workaround to
compute Cext - compute Csca
by using command line option (-Csca) and then add it
with Cabs (which is computed correctly). I.e. Cext=Cabs+Csca.
We will address the issue by the
next release (1.1). For more details and status updates please see http://code.google.com/p/a-dda/issues/detail?id=134
It is important to note, that this
issue affect _only_ Gaussian beams and _only_ calculation of Cext (or Qext). Other parts of
light scattering by particles with incident Gaussian beam, e.g. the Mueller
matrix, has been tested against independent methods and are working perfectly
fine:
http://code.google.com/p/a-dda/wiki/ComparisonOtherCodes#Comparison_with_the_multiple_multipole_program
There also exist another issue when
computing the radiation force due to the Gaussian beam: http://code.google.com/p/a-dda/issues/detail?id=135
However, the radiation force calculation is still in development anyway, so
this issue will be fixed during the future development.
Best regards, Maxim Yurkin.
