The Global Ozone Monitoring Experiment-2 (GOME-2) instrument continues the long-term monitoring of atmospheric trace gas constituents started with GOME / ERS-2 and SCIAMACHY / Envisat. Currently, there are three GOME-2 instruments operating on board EUMETSAT's Meteorological Operational satellites MetOp-A, -B, and -C, launched in October 2006, September 2012, and November 2018, respectively. GOME-2 can measure a range of atmospheric trace constituents, with the emphasis on global ozone distributions. Furthermore, cloud properties and intensities of ultraviolet radiation are retrieved. These data are crucial for monitoring the atmospheric composition and the detection of pollutants. DLR generates operational GOME-2 / MetOp level 2 products in the framework of EUMETSAT's Satellite Application Facility on Atmospheric Chemistry Monitoring (AC-SAF). GOME-2 near-real-time products are available already two hours after sensing.
The operational HCHO total column products are generated using the algorithm GDP (GOME Data Processor) version 4.x integrated into the UPAS (Universal Processor for UV / VIS Atmospheric Spectrometers) processor for generating level 2 trace gas and cloud products.

Laserpunkte sind dreidimensionale Punktkoordinaten (Rechtswert, Hochwert, Höhe) der gemessenen Reflektionen aus der Airborne Laserscanning Befliegung, wobei die Geländeoberfläche mit einem Laserstrahl abgetastet wird. Die Messpunkte des Lasers fallen dabei nicht nur auf die Geländeoberfläche, sondern treffen auch auf Objekte, die sich darüber befinden wie z. B. Bäume oder Gebäude. Durch geeignete Filtermethoden wird die Punktwolke automatisch in Punktklassen Bodenpunkte, Objektpunkte, nicht zuzuordnende Punkte in Bodennähe und Gebäudepunkte unterteilt. Neben den aufgelisteten Referenzsystemen sind die Laserpunkte in den Systemen ETRS89 / UTM32 mit Zonenkennzahl (EPSG:4647) und ETRS89 / UTM33 mit Zonenkennzahl (EPSG:5650) verfügbar.
Fog water samples were collected in the Arctic during the PS106 campaign (2017). Sampling was conducted on board the German research vessel Polarstern. These fog water samples were measured on pH, combined carbohydrates (CCHO) and dissolved free carbohydrates (DFCHO). Sampling altitude: ca. 21 m above sea level.
Size-resolved aerosol particles were collected in the Arctic during the PS106 campaign (2017). For the collection of the aerosol particles, a five-stage low-pressure BERNER impactor was used. The size of the particles ranged between 50 nm and 10 µm. Sampling was conducted on board the German research vessel Polarstern. These aerosol particle samples were characterized on total aerosol mass concentration, combined carbohdrates (CCHO) and organic carbon (OC). Sampling altitude: ca. 25 m above sea level.
