Fig. 4. Clusters of methane plumes in Turkmenistan with distinct sources.
(A) Twelve methane sources with an aggregate emission of 163 ± 18 tonnes CH4 hour−1 acquired at 4:28 UTC on 15 August 2022. The inlay shows a repeat mapping of this region on the same day (10:58 UTC) with visible differences in the plume shapes associated with changing wind conditions. Infrastructure locations are shown for the Goturdepe (pink), Barsagelmez (green), and Burun (orange) fields, as well as gas (light gray) and oil (light blue) pipelines. (B) Fifteen sources all within the Dauletabad-Donmez field, with an aggregate emission of 64 ± 12 tonnes CH4 hour−1.
