IPC - XI
Davos, 27 September -
The Eleventh International
are organized by the World Radiation Center (WRC) on behalf of the World
Organization (WMO). The IPC-XI are combined with the Regional Pyrheliometer
(RPCs) of all regions.
The IPC-XI will be held 27 September - 15 October 2010
at the Physikalisch-Meteorologisches Observatorium Davos
(PMOD/WRC) in Davos Dorf, Switzerland.
Online registration is now open!

station of Davos Dorf.
Davos is located in the mountains of Grisons, the
easternmost canton of Switzerland at an elevation of 1560 meters above sea level. The average
minimum temperatures in September are -1.1°C and -4.8°C in
The average daily maximum temperatures reach 21.4°C and
average sunshine duration is 55% of the possible sunshine duration. A

skiing and hiking resorts in the Alps.
How to get to Davos
For most IPC-XI participants
it will be most convenient to fly into Zurich
airport, which is Switzerland's largest
Zurich international airport is directly linked to Switzerland's
network. In most cases you will have to travel through
Zurich main station (Zürich HB). From there intercity trains leave every hour on the minute 37 with connecting
at Landquart to Davos
Dorf. Intercity and commuter trains connect
Zurich airport with Zurich main station several times

reservation is possible but not normally necessary. For a fee of
~20 Swiss Francs per piece luggage can be sent by train
but will arrive only on the following day at your destination.

Arrangements have been
made with the Hotel Meierhof in
Davos Dorf to
the IPC-XI participants. The hotel is within a ten minutes walk
As in previous years, Hotel Meierhof offers a very favourable deal
compared to normal room rates in Davos.
A hotel reservation form will be be sent to you after you register for
PROGRAM FOR THE FIRST
A welcome reception will be held on Sunday evening, 26
September at the Hotel Meierhof.
Monday morning will be dedicated for instrument set-up
and test runs.
The comparisons are
intended for working
pyrheliometers such as absolute radiometers and compensation
of the Ångström type.
Each participating instrument must be accompanied by all necessary
equipment (including a solar tracker)
and trained personnel to allow self-contained operations. No assistance
be provided by PMOD/WRC in making the observations.
PMOD/WRC will provide bench space for each
institution/center with a power outlet (230V AC or 110V AC, 50 Hz). A
limited number of 110V, 60 Hz outlets can be provided if
needed, as well as 2 or 6 V DC for Ångström pyrheliometers. If necessary, laptop computers will be provided for
data ingestion into the central data acquisition
system. Participants may also use their own WLAN equipped device to
connect to a web interface for submitting their
data. Participants must provide their own sun tracking
Storing space for instrumentation will be available inside the
PMOD/WRC main building.
Procedures and Data Acquisition
Measurements will be
taken in series of
minutes duration with a 90- seconds base cadence. A 30-seconds
sub-cadence is currently being evaluated for HF and similar type
instruments. Visual as well as aural guidance will
ensure proper synchronization of the
Participants are required to maintain a log-book (either
electronic or on paper) of all their readings. Data
submission to the IPC-XI data acquisition computer has
to occur either manually via the dedicated web
interface in real-time or by file upload to the
dedicted FTP directory.
For connecting to the web
interface laptop computers will be provided to
participants who do not have their own WLAN capable
device. If you plan to upload your readings to the FTP
directory please make sure your data files accord with the
file name and data
If possible the output of individual values keyed-in by the
will be handed out for checking after each series. At the end of the
day, all results will be posted.
A wireless LAN (WLAN) connection will be available to connect to the
data acquisition computer.
TRANSPORTATION OF INSTRUMENTS
Negotiations are currently under way with
Swiss customs authorities to simplify import and
export procedures for IPC-XI equipment and
instruments. Details will be announced as soon as available.
The costs for transportation are at the expense of the participant.

SYMPOSIUM AND COURSE
On cloudy days symposium talks and a course on radiation
measurements will be given. A detailed program for
the course on radiation measurements is currently being
compiled by CIMO experts.
Participants are encouraged to prepare a
presentation in order to share
exprience with radiation measurement and/or
RADIOMETER COMPARISON (FRC-III)
Filter Radiometer Comparison (FRC-III) will be held again during the
IPC-XI. Please check back soon for more information.
OF PV PANELS
Several participants of previous IPC's have
expressed their interest in a PV (photovoltaics) panel
intercomparison. PMOD/WRC cannot offer spectroradiometer
measurements or any other significant expertise in the
field of PV. Nevertheless, IPC-XI participants may bring and operate their PV
panels alongside their pyrheliometers, space and other
resources permitting. Interested parties may
contact Wolfgang Finsterle (wolfgang_at_pmodwrc.ch) who will then try to
coordinate their needs.
