| − | ===Inventory=== | + | ===Remaining To Do for fall=== |
| − | * Use Aluminum tripod from Museum | + | * Bring out a charge controller for solar panel |
| − | * Need to replace some bolts... take care of this 8/3 (Aisle was closed at Home Depot)
| + | * soil samples from soil pit |
| − | ** See clipboard for info
| + | * soil pit sensors are in a large actionpacker next to tower. |
| − | * Reuse the 10' x 1" pipe up top used the by the cameras for the net radiometer cross arm
| |
| − | ** I think we'll need to have a vertical support partway out the pole to keep it all level.
| |
| − | ** could use unistrut for all of this but will need to drill a hole in one of the unistruts because the holes don't entirely line up.
| |
| − | ** ubolt horizontal unistrut to tower
| |
| − | ** ubolt 1" pipe to horizontal unistrut
| |
| − | ** partway out horizontal pipe then add a vertical piece of unistrut.
| |
| − | **
| |
| − | * Two batteries up top. We'll need to helicopter these up.
| |
| − | * battery box for up top remains in 106 to carry sensors out in second shipment.
| |
| − | * Cross arms: | |
| − | ** Net radiometer
| |
| − | ** additional one for AT/RH
| |
| − | ** Need to figure out what to do up top for the anemometer...
| |
| − | *** 3/4"insert is up there but need to go 3/4" to 1" vertical...
| |
| − | * '''Complications'''
| |
| − | ** crossarm ubolts from Campbell aren't big enough diameter to go around this pipe.
| |
| − | **
| |
| − | ====Anchoring system====
| |
| − | *
| |
| − | ===Sensors===
| |
| − | * 1 Soil pit
| |
| − | ** Hydraprobes @ 5 depths
| |
| − | ** soil thermal conductivity at 4 depths
| |
| − | ** one additional surface temperature
| |
| − | * 1 GIPL VATP (I'm on the fence about the length for this one)
| |
| − | * Met
| |
| − | ** HMP155 AT/RH @ 1.5m ''(already up top)''
| |
| − | *** Radiation shield too
| |
| − | ** RM Young anemometer for up top
| |
| − | ** If have enough, a skin temperature sensor (SI-111)
| |
| − | ** CNR4 Net Radiometer ''(already up top)''
| |
| − | ** TE525MM with cable.
| |
| − | *** Calibrated in the lab, read 52.4 mm when it should have read 60mm. Therefore, in program, use multiplier 60/53*0.1 = 0.113 instead of 0.1
| |
| − | * Anything else?
| |
| − | | |
| − | ===Extras===
| |
| − | * Need to measure resistance of heaters for all thermal conductivity sensors
| |
| − | * need to color code all subsurface sensors
| |
| − | * need to make sure extension cords are included for solar panel to charge controller
| |
| − | * same for battery to charge controller
| |
| − | * and again logger to charge controller
| |
| − | * also need fused power and spare fuses
| |
| − | * power jumper cables to put the two batteries in parallel
| |
| − | * Need to drill out hole in battery box for the liquid-tite.
| |
| − | * need to trim back the Vitel cable so that we can wire them up properly
| |
| − | * need to include terminal strips for power, ground, and control of Vitels.
| |
| − | * probably need to figure out if we need additional terminal strips for the thermal conductivity.
| |
| − | | |
| − | | |
| − | ===To Buy up top:===
| |
| − | * 1" unistrut pipe clamp for net radiometer
| |
| − | ** may have this in our unistrut stock.
| |
| − | * Anchoring system supplies
| |
| − | * review photos for nome storage stock.
