MAGIC4AMPAC project: Flux Report

The ESA-funded MAGIC4AMPAC project addresses the sparse data coverage in the high northern latitudes by focusing on selected airborne observations from two separate field campaigns that took place simultaneously in Lapland: MAGIC-2021and HEMERA-2021. The Arctic Methane and Permafrost Challenge (AMPA...

Description
Summary:The ESA-funded MAGIC4AMPAC project addresses the sparse data coverage in the high northern latitudes by focusing on selected airborne observations from two separate field campaigns that took place simultaneously in Lapland: MAGIC-2021and HEMERA-2021. The Arctic Methane and Permafrost Challenge (AMPAC) is a transatlantic initiative by NASA and ESA. MAGIC is a French initiative and stands for Monitoring of Atmospheric composition and Greenhouse gases through multi-Instruments Campaigns. This report adresses the methane observations of different platforms at MAGIC-2021, incl. instrument intercomparison. Comparisons to satellite observations are described in detail in a previous report and only shortly summarised here. Modelling was included in the project only marginally, but various modelling efforts turned out to be crucial for analysing the observations. These are described here, together with emissions inventories. The focus of the report is on attempts to derive fluxes from airborne remote sensing instruments and on approaches to derive fluxes from airborne in-situ measurements of methane mixing ratios.
