Currently we are working on setting up the mass flow controller (in one of the images) and calibrating it to establish the leak rate of 8 liters/minute. I am specifically focused on getting the tubing measured out while getting connectors to attach the tubing to the instruments, but I ave also helped quite a bit with the wiring (like on the breadboard you see in the picture). Soon we will finish getting the gps synced with all of the other instruments and we will be ready to run our preliminary tests in the field. These preliminary tests will be focused on safety and we will set up a few sensors and just measure for the average concentration. From there we will begin to actually use the cart a start getting an idea of the shape of the plume.
