IUP Bremen Sentinel-5p support for CHACHA
Introduction Data References Links Contact
Introduction:
|
The CHACHA campaign (CHEMISTRY IN THE ARCTIC: CLOUDS, HALOGENS, AND AEROSOLS) aims to improve understanding of atmospheric chemistry that impacts ozone, particulate matter, and cloud chemical composition in the context of a rapidly changing Arctic. More information on the CHACHA campaign is available on the CHACHA home page. |
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 CHACHA observations in spring 2022. 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.

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. Where several measurements are available for the same day, the maximum is shown. 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, 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.
