(2) PhD scholarship "Relativistic electrons in electric discharges" at
DTU Space in Denmark - due 31 Jan.
---------------------------------------------------------------------------
From: Torsten Neubert (neubert at space.dtu.dk).
A three-year PhD scholarship is available at DTU Space, with start date March
1st 2010 or as soon as possible thereafter.
The project will study how electrons are accelerated to relativistic energies in
electric discharges in the atmosphere. The question has been raised after the
surprising observations from satellite of high-energy radiation from the
atmosphere above powerful thunderstorms, later followed by the discovery of
radiation from lightning and from laboratory discharges. It is now understood
that the radiation is bremsstrahlung from electrons that are accelerated to
unexpected high energies. The acceleration process is not understood but is
interesting because it influences the dynamics of the discharges and their
effect on the atmosphere.
The microphysics of discharges is relatively unexplored because of its
complexities. DTU Space has developed numerical methods to study the phenomenon
with very high precision of the electron dynamics. These will be used to study
the conditions for electrons to reach high energies and their influence on the
discharge dynamics. The simulations will be evaluated relative to measurements
from laboratory experiments.
The position, which is funded by The Danish Council for Independent Research |
Natural Sciences, is related to a mission planned for the International Space
Station: "The Atmosphere-Space Interactions Monitor" (ASIM)
for observations of extreme thunderstorms and their influence on the atmosphere.
ASIM is led by DTU Space in collaboration with the Danish company Terma.
Qualifications
Candidates should have a master's degree in engineering or a similar degree
with an academic level equivalent to the master's degree in engineering.
A PhD student is sought with good background in physics and numerical methods.
The study will be conducted in collaboration with researchers at the Technical
University of Eindhoven, Holland, and the Russian Federal Nuclear Center -
VNIIEF, Sarov, Russia.
Approval and Enrollment
The study will be under the DTU Space PhD network "Space Science and Technology"
http://www.space-phd.dk/English.aspx. The scholarships for the PhD degree are
subject to academic approval, and the candidates will be enrolled in one of the
general degree programmes of DTU. For information about the general requirements
for enrollment and the general planning of the scholarship studies, please see
the DTU PhD Guide
Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD
degree students. The period of employment is 3 years.
The study will be based on the DTU Space "south" office, Juliane Maries Vej 30,
close to downtown Copenhagen. The student will organizationally be under the
Department of Solar System Physics.

(3) "Long-Term Changes and Trends in the Atmosphere", June 15-18, 2010,
Boulder, CO.
----------------------------------------------------------------------------
From Liying Qian (lqian at ucar.edu).
The 6th IAGA/ICMA/CAWSES workshop on "Long-Term Changes and Trends
in the Atmosphere" (http://www.hao.ucar.edu/TREND2010/index.php) will be held at
National Center for Atmospheric Research (NCAR) Center Green Conference Center,
Boulder, Colorado, USA, June 15-18, 2010, the week before the 2010 CEDAR
(Coupling, Energetics, and Dynamics of Atmospheric Regions) workshop, which will
also be held in Boulder.
We are glad that this workshop coincides with the 40th year of uninterrupted
work of Ray Roble, who has made substantial contributions in the topic which
became a major theme of the workshop. It has been 20 years since Roble and Dickson
[1989] first concluded that global change will occur in the upper atmosphere as
well
as in the lower atmosphere as a result of increased greenhouse gas concentrations.
Since this workshop will be held at NCAR where Ray has worked for nearly 40 years,
a special session will be dedicated to Ray Roble to honor his contribution to
this field, featuring a lead presentation given by Ray Roble followed by a few
review talks
summarizing the advances in this field after the pioneering path shown in 1989.
Long-term changes to Earth's atmosphere are becoming more and more relevant
to the future of our world and it is paramount that we quantify and understand
changes occurring at all levels within the coupled atmospheric system. The
increasing
concentration of greenhouse gases, stratospheric ozone depletion, varying solar and
geomagnetic activity, secular change of Earth's magnetic field, and changing
dynamics propagating up from the troposphere are some of the possible causes of
long-term changes in the stratosphere, mesosphere, thermosphere and ionosphere. The
goals of this workshop are to review the current state of knowledge about trends in
these atmospheric regions, and to discuss what research is necessary for resolving
inconsistencies, reducing uncertainties, and achieving a deeper understanding of
middle and upper atmospheric climate change, especially the relative influences of
anthropogenic and solar effects.
We welcome papers using all types of observational techniques to determine the
long-term changes and trends that have occurred in the past and also to
determine the
processes behind those changes. We also welcome contributions which consider the
availability, quality and acquisition of various data sets which may be
exploited for
trend studies, and statistical methods for deriving and validating those trends.
Interpretation and attribution of observational results depends heavily on
theoretical
models and numerical simulations of the trends, and presentations dealing with
these
topics are particularly welcome. While the troposphere is not the main focus of the
workshop, it is clear that it has a major role to play in middle and upper
atmosphere
trends; papers that demonstrate this relevance are also welcome.

(6) ARECIBO CALL FOR PROPOSALS - due 1 Feb 2010.
----------------------------------------------------------------------------
From Sixto Gonzalez (sixto at naic.edu).
Arecibo proposals submitted for the Monday, 1st February 2010 deadline
are for using the telescope in the eight months beginning 1st June 2010
(i.e. valid for two trimesters).
(1) A high percentage of Arecibo telescope time is being used for large
surveys. However, we STRONGLY encourage the submission of
innovative proposals that are not classified as surveys.
(2) A 700-800 MHz receiver is available for use in the band
(temporarily) freed up by the recent TV channel reallocation. This
receiver is continuously being improved. Proposals are encouraged
on a shared risk-basis, subject to the evolution of band occupancy,
and the practicality of use. The RFI situation as of 12 August,
2009, (when the last major TV turned off) can be seen via:
http://www.naic.edu/~phil/800/800rfi.html#12aug09
(3) The 2 x 7 dual-polarization channel, 300-MHz bandwidth, "Mock"
spectrometers are available to all ALFA users. For details see
http://www.naic.edu/~astro/mock.shtml
(4) A partial implementation of a NEW SINGE-PIXEL MODE for the Mock
spectrometers is available, which enables their combination such as
to provide up to 1 GHz of contiguous spectral coverage. On-line
pulsar folding is not yet supported.
(5) The WAPP spectrometer provides an 8-band, dual-polarization,
single-pixel observing capability for spectral lines or pulsars.
This mode can be used to place 8 simultaneous bands, each of up to
100-MHz bandwidth, as desired within a 1-GHz band. 680 MHz of
contiguous spectrum can be covered allowing for filter roll-off.
An overview of the present capabilities of the WAPP backend is to
be found at: http://www2.naic.edu/~wapp/
(6) Large proposals, (i.e. those requesting at least 300-400 hr --
though at the NAIC Director's discretion, sometimes less than
this), are subject to skeptical review after evaluation by the
normal science referees. Progress reports of existing large
proposals will be skeptically reviewed annually. All skeptical
reviews will take place in August.
(7) A policy for follow-up proposals by survey consortia has been
included as Section 5.8 of the web document detailing information
about Proposals & Policies, see :--
http://www.naic.edu/~astro/proposals/proposal.shtml#5
Please note that the 610-MHz receiver is no longer available. Also,
while we try to keep the maximum possible number of receivers cooled
and ready for observing, this may not always be possible. Thus
availability of the S-high and C-high receivers cannot always be
guaranteed, and these receivers will often be scheduled in campaign
mode.
------------ Arecibo Observing Information --------------------------
Proposal submission details, and a web-based cover sheet, can be found
at http://www.naic.edu/~astro/proposals/. A guide for new users of the
telescope is at http://www.naic.edu/~astro/guide. Other user-related
information is at http://www.naic.edu/~astro/astronomy.htm.
Radio sources with declinations of about -1 < Dec < +37.5 deg are
visible from Arecibo, and can be tracked over the range of zenith
angles between 1.1 and 19.7 deg.
Available receivers in the (frequency-agile) Gregorian Dome, their
frequency coverage, typical System Temperature, Telescope Gain and
System Equivalent Flux Density (SEFD = Tsys(K)/Telescope_Gain(K/Jy))
are:

X 7.8 - 10.2 GHz 28 - 35 2.5 - 5.5 7.5 (9 GHz)
----------------------------------------------------------------------
To these should be added the 47 and 430-MHz systems in the Carriage
House. For the latter;
----------------------------------------------------------------------
Rx-name Freq. coverage Tsys (K) Gain (K/Jy) SEFD (Jy)
----------------------------------------------------------------------
CH430 425 -- 435 MHz 60 - 100 8 - 16 3.5 - 12
----------------------------------------------------------------------
Pulsar, spectral-line, VLBI, and continuum backends are available to
exploit all these receivers.
The Arecibo Mk-5A disc-based recorder for Very Long Baseline
Interferometry (VLBI) is available for use with the HSA, EVN and Global
networks at all bands up to 10 GHz. Those wishing to include the
ultra-high sensitivity of Arecibo in their VLBI observations should
submit proposals directly to these networks rather than to Arecibo,
including justification for the use of the 305-m telescope. The
maximum data recording rate at Arecibo is currently 1 Gbps. However,
HSA observations are limited to a maximum data rate of 512 Mbps. eVLBI
science runs with the EVN have been made up to 512 Mbps.
The Mk-5A system is also available for single-dish baseband-sampled
data recording.
