Dear Colleagues,

you receive this eMail because you are either a user of the radiative
transfer package libRadtran or because we think that you might be
interested in this information. Should you not be interested in
receiving further information, please let us know!

Attached to this eMail is the 12th libRadtran Newsletter. The main
issue of this Newsletter is to send Seasons Greetings!

You have probably been desparately waiting for the Christmas release
of libRadtran which, in an old tradition, is announced on Christmas eve
each year. Following a more recently established tradition (introduced in
2009), however we decided to allow some more testing, polishing and
fine-tuning and to postpone the release to about end of January. There
will be some great new features including e.g. a translation of libRadtran
to C (provided by Tim Dowling), a completely re-designed manual,
considerably improved optical properties for water and ice clouds, etc.

Below you will find an announcement of a first libRadtran user
workshop which we plan for 2011. For better planning we would be
interested in who seriously considers attending this workshop.
Please let us know!

And now, we wish you all a Merry Christmas and a happy
and successful New Year!

Bernhard Mayer, Claudia Emde, Robert Buras, and Arve Kylling.

*** libRadtran workshop ***

For the first time we plan to organize a libRadtran workshop. The aim
of the workshop is to teach and to present the libRadtran software
package for radiative transfer in the Earth's atmosphere to
investigators and students. Both basic and advanced topics will be
taught. Familiarity with general radiative transfer theory is
recommended. The workshop will take place in September 2011. The location
is yet to be decided; we are currently investigating several options
in central Europe.

The workshop includes both lectures and hands-on exersizes. The
following topics will be covered: Overview of radiative transfer in
the Earth's atmosphere; overview of the libRadtran package; the
radiative transfer equation solvers in libRadtran; optical properties
of ice and water clouds; optical properties of aerosols; surface
properties; specific radiative transfer applications utilizing
libRadtran. The particpants will be encouraged to present their use
of libRadtran.

The principal instructors include Bernhard Mayer, Arve Kylling,
Claudia Emde, and Robert Buras.

To ensure sufficient availability of instructors at the hands-on
exersizes, the number of participants will be limited. Registration
will be on a first come, first served basis. If you are interested,
please send an e-mail to
Dr. Claudia Emde <claudia.emde@physik.uni-muenchen.de>
by January 31, 2011. A minimum number of 15 participants is required to
run the workshop.
