July 2009, SUMO flew meteorological soundings at Álfsnesi and Kollafjordur, Iceland. Hálfdán
Ágústsson and Maríus Opsanger Jonassen gave an interview for the Icelandic TV news.
21. March - 04. April 2009, SUMO contributed with 85 flights for investigations of the spring time Arctic Atmospheric Boundary Layer. During the campaign SUMO has been operated simultaneously in a horizontal distance of 1 km.
FLUXPAT III, Germany
||04. - 23. August 2008, as a part of the larger T32 project, the FLUXPAT III
measurement campaign took place near Jülich in Germany. The main focus
of this campaign was to study the mechanisms leading to spatial and
temporal patterns in energy and matter fluxes of the
soil-vegetation-atmosphere system. SUMO was used to close the
observational gap between measurements by a Dimona aircraft from MetAir
AG and masts at the ground.
||17. - 28. July 2008, we were guests at a field course for german meteorology students from Munich at Flugplatz Steinrücken.
Together with piloted balloon ascents, SUMO was used during a night in
order to investigate the development of the nocturnal (stable) boundary
Profiling the Arctic Atmospheric Boundary Layer
||25. February - 13. March 2008,
SUMO was successfully operated under harsh Arctic conditions on and
around Spitsbergen. During this campaign, both take-offs and landings
of the SUMO aircraft were performed from the helicopter deck of the
Norwegian coast guard vessel KV Svalbard. The campaign was carried out
as a part of the IPY-THORPEX and partly funded by the Norwegian Polar Institute.

FLOHOF -FLow Over and around HOFsjökull
||13. - 18. August 2007,
the first infield test of SUMO was performed. This milestone in the
SUMO project took place under the international field campaign FLOHOF,
in Central Iceland. More information on this campaign, which had its
focus on instationary gravity waves, can be found here.

SUMO is equipped with the autopilot system Paparazzi. The airframe is a commercially available model aircraft construction kit. The main components of SUMO in terms of the underlaying Paparazzi autopilot system consist of:
- airframe equipped with an autopilot controller board
- ground control station (GCS)
- telemetry link for online data transfer
- remote control (RC) transmitter as safety link
soundings SUMO is equipped with a set of meteorological sensors for
temperature, relative humidity (SHT75 from Sensiron) and pressure
(SCP1000 from VT1 Technologies). Temperature and humidity sensors are
attached under the wing (good ventilation, protected against direct
solar insolation). The pressure sensor is mounted in the fuselage of
SUMO where it is directly coupled with the autopilot controller board.
