Open-path mid-range remote sensing techniques for GHG emission fluxes – A suitable approach to improve up-scaling of spot measurements?

IRF has defined ’Climate’ as a new focus area within the observatory KAGO (Kiruna Atmospheric and Geophysical Observatory). The rationale for that is manyfold: location, expertise, existing climate research in nearby Abisko including infrastructure and national and global networks, to name some of them.
We want to initiate a campaign in Stordalen in northern Sweden, setting up an open-path remote sensing experiment for the observation of greenhouse gases CO2 and CH4 over different types of landscapes, such as lakes, forests of different kind, and wetland with and without permafrost.
The existing international research on climate change and climate impact going on in the Abisko region in Northern Scandinavia has gathered research data over many decades back in time, based on in-situ (spot) measurements. However, in the process of developing a larger, regional or even global picture, modelling uncertainties, mainly due to the problem of up-scaling of very local observations, are inevitable. Here a remote sensing technique covering several tens of square kilometer could close a gap and improve up-scaling of local concentrations and fluxes of greenhouse gases

In the presentation I will explain idea, the means and the goals of a summer campaign in the Abisko field site 'Stordalen'.
