In this report, 2 novel instruments are described that are able to measure the ammonia emissions of manured fields. The 1st instrument, developed and operated by ECN, is a tuneable diode laser spectrometer (TDL), mounted in a van. It is used to measure the ammonia concentration patterns downwind from a manured field. Wind measurements, a nitrous oxide tracer and a simple Gaussian plume model are used to calculate the ammonia emission. The 2nd instrument, built by RIVM, is a mobile lidar system… Expand
