vidaloo,
There are only three days of imagery available at any time, it is not archived. There are no csv or text files of the data. To create Methanetracker, Omar Cabrera took each image and pulled the locational and CH4 reading data for each point, which was a fair amount of coding.
Crandles,
Thanks for the perspective on the historical rate increase. It is of concern. I am interested in what an El Nino will do to that rate in the coming years, if one develops. Methane increase rates have declined since 1984, but there is variability in the pattern with increases and decreases correlating with El Nino, in the WDCGG monthly data.
