Measurements of green house gases (and fluxes) + measurements of particle size distributions
a. Micrometeorological fluxes
b. Calibrated atmospheric concentrations
Carbon dioxide and methane emissions and uptake,
sensible and latent heat (evaporation) fluxes within an area of 300-500 radius around the micrometeorological mast, located 50-100 m from the TCAF to the south
4 meter high mast
Sampling tubes from the anemometer to the instruments in the cabin
Los Gatos Res. CH4 analyser
On the wall right: optical isolators between the instruments and PC and the data collection board for the meteorological instruments
On the floor pumps for the analysers
Carbon dioxide and methane concentrations will be measured in the TCAF,
sampling from the inlet stack
Working standard gas cylinders
LiCor CO2/H2O,gas valves and flow controllers
Standard gas cylinders
Gas Chromatograph for CH4, N2O, CO, SF6
At TCAF only CH4 will be measured using Los Gatos Res. CH4 analyser
Is it possible to have a cabin for the micrometeorological studies?
If so, is it better to produce it Finland or in Russia (in Finland it costs 3500 euros)?
Transportation to Russia (the company, Rääkkylän muovi, has already produced different size cabins to Siberia)
We will need 4 m high mast, which is a simple structure. Production in Finland or Russia?
How high is the sample gas inlet stack in TCAF?
We would like to suggest 20 m high stack because the tundra surface close by acts as a source and sink of CO2 and CH4
How is the availability of synthetic air cylinders to Tiksi from Russian suppliers?
Also butanol (purity >99%) for CPC’s
Customs costs?, in the case instrumentation will be donated to the ROSHYDROMET?
Also the aerosol instruments
