Kevin Smith, STFC
There are two groups within STFC’s RAL Space that are interested in developing ammonia emissions monitoring systems. One idea has been proposed for STFC Challenge Led Applied Systems (CLASP) funding and would develop a prototype instrument using passive microwave technology for measurements in animal houses or over fields. The other is a system that would allow eddy covariance measurements for identifying sources and sinks of ammonia in the environment. This would use an STFC-patented technique called laser dispersion spectroscopy enabling measurements to be made with 1ppb sensitivity at 10Hz. I’d be very happy to put you in touch with the scientists involved if useful.
