However, I think we should stay as constent as possible both for dataformat and metadata, for example keeping the sama date format, nomenclature for flagging data etc. I also think we should try to keep the same format for individual type of measurements (e.g., ground, drones, aircraft).Also, it is a good idea to assign ID number to each isntrument used during the campaing and keep this number in the name of datafile. I am aware it will require a lot of discussion to come to the consensus in the matter of common dataformat and at the end should be also discussed with someone from Carbon Portal.</div><div><br data-mce-bogus="1"></div><div>Cheers,</div><div>Sara</div><div><br></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"Dr. Sven Krautwurst" <sven.krautwurst@iup.physik.uni-bremen.de><br><b>To: </b>"Dominik Brunner" <Dominik.Brunner@empa.ch>, "Sara.Defratyka" <sara.defratyka@lsce.ipsl.fr><br><b>Cc: </b>"ute karstens" <ute.karstens@mgeo.lu.se>, "margareta hellstrom" <margareta.hellstrom@mgeo.lu.se><br><b>Sent: </b>Tuesday, 17 February, 2026 15:17:41<br><b>Subject: </b>Re: AW: [Im4ca-wp1.beta] Proposed Agenda WP1 meeting 18.02<br></div><div><br><style>@font-face

in addition to Dominik's reply, we would also share the XCH4 column
maps (or column anomalies) as NetCDF-files and kmz Google Earth
quick-look data rather than the raw spectra, as this seems the most
reasonable approach.<br>
If someone is interested in the raw data or spectra at a later date,
this can be discussed of course.<br>

we can produce XCH4 columns as a derived product, which will

<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US">Dear Sarah,<br>
<br>
I have just shortly discussed the "datasharing" with
Konstantin.<br>
<br>
I was wondering if it is possible to use two different
formats — one for in situ data and one for remote sensing —
without knowing exactly what has been discussed so far, for
example, in Switzerland. The two data types (IS vs. RS) look
quite different and thus have different requirements for the
file format concerning metadata or storage place. <br>
<br>
In our case at the University of Bremen (MAMAP2D-Light), we
have created NetCDF4 files for our remote sensing data, in
accordance with the "ESA Climate Change Initiative Plus
(CCI+) Product User Guide \- TROPOMI WFM-DOAS XCH4 for the
Essential Climate Variable (ECV) Greenhouse Gases (GHG)"
--> our format is based on a satellite data fromat.<br>
However, this may already be quite different to the one that
Dominik and his team are using.<br>
<br>
Best, <br>
Sven<br>
