<p class="MsoNormal">Dear all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the meeting last week, the possibility for a paper focused on landfill-emissions was discussed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To get this started and to get an overview of the different measurements from the campaign, I started

this document</a> on the research drive (WP1 -> Data -> Romania Campaign -> overview_landfill_measurements.xlsx).
<o:p></o:p></p>
<p class="MsoNormal">There is one sheet per landfill and one sheet with the landfill locations to clear up the landfill naming, should my naming convention not align with yours.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can every team that performed measurements around landfills fill this in, so we know when, what and by whom was measured?
<o:p></o:p></p>
<p class="MsoNormal">I think this would help to think about if and how we can best combine our data towards a common study.
<o:p></o:p></p>
