HALO database

HALO-DB is the web platform of a data retrieval and long-term archive system. The system was established to hold and to manage a wide range of data based on observations of the HALO research aircraft and data which are related to HALO observations. HALO (High-Altitude and LOng-range aircraft) is the new German research aircraft (German Science Community (DFG)). The aircraft, a Gulfstream GV-550 Business-Jet, is strongly modified for the application as a research platform. HALO offers several advantages for scientific campaigns, such as its high range of more than 10000 km, a high maximum altitude of more than 15 km, as well as a relatively high payload.

High resolution aircraft measurements of wind and temperature during the MOSAIC-ACA campaign in 2020

During the MOSAiC-ACA campaign conducted in August/September 2020 in Svalbard meteorological data (temperature, 3 wind components, air pressure) have been measured in high temporal resolution (100 Hz) using instrumentation that was installed at the nosebooms of Polar 5. For each flight the data are given as functions of time and position (including height above ground) along the flight tracks. All flights started and ended in Longyearbyen, Svalbard. Each file represents an entire flight starting well before the first movement of the plane and ending after the final parking position has been reached after landing. The wind measurement is only valid during flight and the full accuracy is only achieved during straight level flight sections. The absolute accuracy of the wind components is 0.2m/s for straight and level flights sections and the relative accuracy of the vertical wind speed is about 0.05m/s for straight and level flight sections. For these sections, which can be obtained on the basis of the given roll and pitch angles of the aircraft, the 100 Hz data can be used to derive turbulent fluxes of momentum and sensible heat. For further informations on the data processing and accuracy of the turbulence measurement refer to Hartmann et al. (2018, doi:10.5194/amt-11-4567-2018).

Master tracks in different resolutions during POLAR 6 campaign P6_235_IceBird_2022

Raw data acquired by GPS1 position sensors on board research aircraft Polar 6 during the campaign P6_235_IceBird_2022 were processed to receive a validated master track which can be used as reference of further expedition data. Novatel FlexPak6 GPS receiver was used as navigation sensors during the campaign. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) with a resolution of 1 sec. Processed data are provided as a master track with 1 sec resolution and a generalized track with a reduced set of the most significant positions of the master track. A detailed report on processing is also available for each flight.

Fluglärm Lden 2022

Berechnungsergebnis Lden (day, evening, night) 2022 nach EU-Umgebungslärmrichtlinie (2002/49/EG, 34. BImSchV) als Isophonenbänder für den Großflughafen Hannover/Langenhagen. Die Berechnung des Pegels Lden erfolgt nach der Berechnungsmethode für den Umgebungslärm von Flugplätzen (BUF). Ermittelt werden diese Pegel rechnerisch in einer Höhe von 4 m über Grund und in einem Raster von 50 x 50 m. Als akustische Quelle dienen die relevanten Flugrouten mit den darauf fliegenden Luftfahrzeugen. Die Darstellung erfolgt in 5 dB Klassen gemäß Legende. Die Geometrie des Pegelrasters liegt in UTM- Koordinaten vor.
