Scientists from CarboAfrica, a programme to study the carbon cycle and other greenhouse gases (GHG) in Sub-Saharan Africa, have announced the successful installation and operation of the Picarro G1301 GHG monitor at a remote field site in equatorial West Africa.
This Ivory Coast location of Station de Géophysique de Lamto is a particularly challenging spot for remote monitoring equipment, due to it’s high humidity and ambient temperature characteristics, that can easily exceed 40°C.
The Picarro G1301 utilises WS-CRDS (wavelength-scanned cavity ring down spectroscopy) technology to deliver simultaneous and continuous measurements of both methane (CH4) and carbon dioxide (CO2) at a precision of parts per billion.
Immunity from cross-talk enables it to achieve this precision with ambient samples, without the need for drying or any other purification. The Picarro analyser is located in a small building adjacent to a 50 meter tower allowing data to be taken automatically and continuously via a tube terminating at the top of this tower.
