Principle of Measurement:
Microcomputer (Tattletale) controlled, flow controlled pumping, with
temperature, humidity, pressure and flow sensors (these data are
logged). Designed to collect 4 samples sequentially.
In situ/Remote/Flux Measurement:
In combination with sevral packages deployed at various altitudes
through the mixed layer on tethered balloon line, the system has been
used to estimate fluxes of biogenic emissions from terrestrial areas.
