Inferring methane emissions from African livestock by fusing drone, tower, and satellite data por Hove, A., Aalstad, K., Lind, Vibeke, Arndt, Claudia, Odongo, Vincent O., Ceriani, Rodolfo, Fava, Francesco P., Hulth, J., Pirk, N.

“…We found a ± 50 % uncertainty in emission rate estimates for these weaker sources, such as sheep and goat herds, which reduced to ± 12 % for stronger sources, like cattle herds emitting 1000–1500 g h−1. Finally, we showed that radiance anomalies identified in hyperspectral satellite data can inform the planning of flight paths for targeted drone missions in areas where source locations are unknown, as these anomalies may serve as indicators of potential methane sources. …”
