Presentation Transcript

  1. Global climate change - Trade carbon credits on international level No current method for soil greenhouse gas measurements H20 removal Chem trap N20 trap Trap N20 Purpose: CO2 and N2O soil emissions quantification Automated process to collect samples occurring every 4 hours for a month period Trap CO2 H20 removal Co2 trap Outside door ATGTD Balance temperature circular air fan Sampling Chamber Equilibrate Process Balance humidity Simulate rain Rain catcher Rain dispersal Trace Gas Trapping Process flux chamber Trap specific volume of air in sub chamber pumpidge Rain dispersal valvidge Rerouting air flow

  2. Simulate Rain Drip Water into Chamber Ensure Quality of Sample Equilibrate Air Activate Fan Remove Unnecessary Elements Remove Moisture Microcontroller Measure Gases Automated Electrical Components Pass Air Through Molsieve and CO2 Trap Control Air Flow Trap N2O Get Samples Trap CO2 Pass Air Through Molsieve
