Quantifying agricultural CH4 emissions using MethaneSAT, MethaneAIR and ground-based data

In this talk, we will present results demonstrating MethaneSAT’s ability to quantify emissions from both intensive agriculture systems and in dispersed pastoral agriculture. We will show analysis of data from over 200 individual agricultural scenes over the United States from MethaneAIR, an airborne precursor instrument to MethaneSAT, which suggest methane emissions from intensive agricultural systems may be systematically under-estimated due to poor quantification of emissions from animal waste.

Current Trends in Synthetic Aperture Radar Imaging Techniques

The talk outlines the principles of Synthetic Aperture Radar and provides an overview of the underlying radar instrument designs and imaging techniques. It then details a specific imaging mode known as f-STEC which explores the SAR trade-space in an unusual way by time compressing the return echo. It is demonstrated how the f-STEC imaging mode can be utilised by both aforementioned trends.
