Method
How we know what we tell you.
Three pages: the instruments we deploy, the references and limits behind every claim, and what we do with the data we collect.
Instruments
What we deploy, what each sensor is actually measuring, and what its stated tolerance is.
References & limitsThe papers and standards we rely on, and the specific things our data cannot tell you.
How we use dataWhat we collect, what we do with it, how long we keep it, and what we will never do with it.
These pages are in preparation. Until they are published, the position each one will state is already set out on the relevant service page — we have not held anything back pending a page being written.
