Why probability of detection doesn’t belong in methane emissions quantification
In the world of fugitive leak detection, probability of detection (POD) is a popular metric. It tells us how likely an individual sensor or network of sensors is to detect a gas signal in a given scenario and is very helpful for leak detection and repair (LDAR) programmes. But when it comes to quantifying methane […]
An overlooked challenge in methane emissions monitoring: background concentration isn’t just background
Methane emissions monitoring is evolving rapidly, with drone-based surveys providing more accurate and reliable solutions than ever before. However, one critical challenge remains: How do we correctly account for background methane concentrations in the atmosphere? And how do we subtract them correctly in the reported emission rate? At Explicit, we’ve spent over a decade conducting […]
Rethinking methane emissions monitoring: It’s not about the leaks
When we talk about methane emissions, the conversation almost always starts with leaks. How to find them, measure them, and mitigate them. At a methane mitigation conference last year, this talk was all the same: leaks, leaks, leaks. As if insufficient maintenance protocols were the root cause of the world’s climate crisis. We beg to […]
Measurement validity: a frequently overlooked key to accurate methane emissions monitoring
A common question in emissions monitoring is: “What’s your measurement uncertainty?” But a far more important—and often overlooked—question to answer is: “How do you know if your measurements are valid?” Without verifying the validity of your sample, you’re essentially sampling blind. You might as well be guessing. And yet, even experienced professionals who work with […]
Why wind also matters in methane emissions monitoring
When discussing methane emissions monitoring, the focus is often on gas concentration: how much methane is emitted and from where. But if you want accurate, actionable measurements, another factor deserves just as much attention: wind. At Explicit, we specialize in accurate emissions quantification, and one thing is clear: understanding wind dynamics is just as crucial […]
