Introduction:
|
The MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) is the first year-round expedition into the central Arctic exploring the Arctic climate system. The backbone of MOSAiC is the year-round operation of RV Polarstern, drifting with the sea ice across the central Arctic during the years 2019 to 2020. During the set-up phase, RV Polarstern entered the Siberian sector of the Arctic in the thin sea ice conditions of late summer. More information on the MOSAiC campaign is available on the MOSAiC home page. |

The Transregional Collaborative Research Centre TR 172 (AC)³ (Arctic Amplification : Climate Relevant Atmospheric and Surface Processes and Feedbacks) provides a unique research environment to study the increase of Arctic near-surface temperature during the last decades, which is commonly referred to as Arctic Amplification, from complementary viewpoints, bridging various observations and modelling approaches. More information on the AC3 transregio project is available here. |
Data:
The IUP-Bremen provides near realtime total BrO columns from the TROPOMI instrument on Sentinel-5p for the project to support measurement planning and quick look interpretation during MOSAiC sunrise observations in 2020. This BrO product is not an official ESA / Copernicus product but a scientific retrieval performed at the IUP Bremen. All plots are produced automatically and without explicit quality control. Usually, the Sentinel-5p plots should be available 24 hours after measurement. If you experience any problems, please contact Andreas Richter.

Animation
An animation of the full spring 2020 time series can be found here (> 10 MBytes).
The products shown here are derived at the IUP Bremen. BrO columns are calculated using a stratospheric air mass factor and no attempt was made to separate between tropospheric and stratospheric parts. most of the clearly enhanced values are indicative of enhanced tropospheric BrO but changes in tropopause height can also lead to larger total columns. The retrievals are based on lv1 data provided by ESA / Copernicus but are not official Sentinel-5p data products. If you want to use them for something else than a quick-look check, please contact us for a consolidated version.
Much more satellite data from GOME-2 and SCIAMACHY are accessible via our data browser page and the SCIAMACHY data archive.
More Sentinel-5p data is available in our group off-line. If you have any requests, please contact Andreas Richter.
