The POLSTRACC Summer Meeting has taken place in Klingenmünster, and latest results on dynamic processes, polar stratospheric clouds, cirrus clouds and chemical processes in the Arctic lowermost stratosphere were presented. The POLSTRACC special issue in the journals ACP and AMT is now open for submissions.
The POLSTRACC Summer Meeting is scheduled for 05.-06. July 2017. We are looking forward to discuss the latest results from the POLSTRACC/GW-LCYCLE/SALSA data.
After an exciting Science Workshop in Klingenmünster, the scientific evaluation of the POLSTRACC/GW-LCYCLE/SALSA data proceeds. The next meeting is planned for summer 2017 at the same location.
After the POLSTRACC/GW-LCYCLE/SALSA Campaign was concluded successfully in March 2016, the first POLSTRACC Science Workshop is scheduled for 09.-10. November 2016 in Klingenmünster, Germany.
With the dismounting of the payload completed, this now finally concludes the POLSTRACC/GW-LCYCLE/SALSA campaign. We would like to thank all who have contributed to make this campaign a great success! With the campaign itself completed, the focus of the work will now shift towards the scientific analysis of the data.
The HALO Kuratorium (supervisory board) visited on Monday, 21 March the POLSTRACC/GW-LCYCLE/SALSA campaign in Oberpfaffenhofen.

HALO science flight PGS_20 was successfully completed today. The flight was particularly tailored to meet the SALSA objectives, with a southernmost latitude of 25°N. A refueling stop in Faro was included on the way back.
Gravity waves over northern Greenland were the focus of HALO science flight PGS_18. The turbulence associated with the strong gravity waves was well noticed on board. (Photo by Björn-Martin Sinnhuber: Gravity waves seen over Greenland.)
Gavity waves and a the tropopause structure around a small polar low off the coast of Norway were the focus of HALO science flight PGS_15 that was successfully completed on 29.02.2016.
HALO has just returned from science flight PGS_13 that went up to 87°N and included a hexagon pattern around Spitsbergen to probe gravity waves. This concludes the first Kiruna phase of the POLSTRACC/GW-LCYCLE/SALSA mission.
With PGS_12 today we finished successfully another 9 hrs HALO science flight. Highlights of the flight were long stretches of PSC observations by the WALES lidar, crossing of the subtropical jet north of Ireland with ozone going down from 900 ppbv to as low as 25 ppbv and high partriculate NOy at the same flight level, and a flight leg under defined constant solar zenith angle conditions for chemistry observations by the mini-DOAS instrument.

HALO has just started for the early winter survey flight. The flight today probes the early polar vortex and leads into the Arctic around Spitsbergen, to Scandinavia, and back to Oberpfaffenhofen. (Photo by Wolfgang Woiwode, KIT)
A three hours instrument test flight was completed and turned out to be very useful. Some instrumental issues have been identified and are being fixed right now. (PLANET screen shot shows flight path.)
The inflight EMC test has been completed sucessfully (see photo by P. Preusse, FZJ). Flight planning for the scientific flights is in progress.
The EMC flight is now scheduled for Tuesday 08.12.2015 and we are considering the options for a first long science flight later that week. Flight planning is in full swing (see photo by T. Leder, DLR).
All necessary documentation needed for achieving the Permit to Fly (PfF) has been submitted to the Federal Aviation Office (Luftfahrtbundesamt, LBA). The pre-briefing for preparing the EMC flight has been completed today. Count-down plans for a possible flight on 3 or 4 December 2015 have been agreed on. We are now waiting for clearance from the LBA.
The Critical Design Review of the combined HALO payload for POLSTRACC/GW-LCYCLE/SALSA and WISE has been performed successfully on 23 June 2015, and no major technical problems have been identified. "Design Freeze" is scheduled for 17 July 2015. The finalization of the instrument Interchange Control Documents is scheduled for mid of September 2015 and will be followed by the "Final Critical Design Review" at the beginning of October 2015.
The Critical Design Review of the POLSTRACC-Payload of HALO is scheduled for 23 June 2015 at DLR, Oberpfaffenhofen.
The POLSTRACC mission will be presented at the European Geosciences Union General Assembly 2015 (Vienna, 12-17 April 2015) in the AS3.12 Polar Ozone and Polar Stratospheric Clouds Session on Thursday, 16 April.
Flight planning associated to the joint POLSTRACC/SALSA/GW-LCYCLE (PGS) campaigns was exercised at the Mission Rehearsal at DLR-IPA, Oberpfaffenhofen.
The instrument test integration during the "Stellprobe" (02.-06.02.2015) at DLR, Oberpfaffenhofen was finished successfully. On 05.02.2015, the Preliminary Design Review was performed and the timeline for the mission preparation phase was refined. During the Status Meeting at the same day, logistic aspects of the campaign phases in Kiruna and scientific flight scenarios were discussed. The Mission Rehearsal is scheduled for 26.-27.03.2015 at DLR, Oberpfaffenhofen.
The "Stellprobe" is scheduled for 02.-06.02.2015 at DLR, Oberpfaffenhofen. In the same week, a Status Meeting will take place at the same location.
POLSTRACC General Meeting at KIT, Karlsruhe: Discussion of the timeline, payload, flight operations, certification and logistics of the joint POLSTRACC, GW-LCYCLE and SALSA campaigns. Data products for scientific flight planning are presented and a Mission Rehearsal is planned for early 2015 at DLR, Oberpfaffenhofen.
