New page

To Do:
* Change out snow transducers, 8 pieces
* swap back the B site net radiometer
* change out desiccant in the D site radiometer
* level radiometers
* Fix C site Rim Snow Sensor

To Bring:
* Two CNR4 Net Radiometers
** One for B and one for D (or.... retap the D radiometer up there... might try that first.)

		+	===Post Trip Notes from Fieldbook===
		+	@ A
		+	* A trough snow mount to corroded to remove so replaced transducer in-place
		+	* Level Net Radiometer (It was close)
		+	* Level Precip (Also close to level)
		+	* Added anti-corrosion goo to net radiometer screws & connections
		+	* Changed desiccant in the box
		+	* Tools Used for Precip bucket leveling:
		+	** 5/16" Nut Driver
		+	** Torpedo Level
		+	* Tools Used for Snow transducer maintenance:
		+	** 1/2" Nut Driver
		+	** Flathead Screwdriver / 1/4" Nut Driver
		+	** channel locks
		+	** phillips screw driver
		+	* In-memory reset of snow depth offset
		+	** SR50A1 = 182.1
		+	** SR50A2 = 126.75
		+
		+	@ B
		+	* Level Net Radiometer
		+	* Swap back original net radiometer
		+	* add anti-corrosion goo to radiometer & lower anemometer
		+	* level precip (it was quite a ways off)
		+	* change snow transducers
		+	* Changed desiccant in the box
		+	* In-memory reset of snow depth offset
		+	** SR50A1 = 177.5
		+	** SR50A2 = Unchanged from program
		+
		+	@ C
		+	* C Trough snow mount to corroded to remove from the mount so transducer replaced on existing sensor
		+	* Precip still level
		+	* Net Radiation Leveled
		+	** 1 screw is stripped on the C net radiometer so I will need to bring the tap & die up on the next trip to fix that.
		+	* Changed desiccant in the box
		+	* Anti-corrosion goo added to net radiometer and lower anemometer
		+	* In-memory reset of snow depth offset
		+	** SR50A1 = Unchaged from program
		+	** SR50A2 = 115.0
		+	** SR50A3 = 117.3
		+
		+	@ D
		+	* Changed net rad desiccant & leveled
		+	* swapped snow transducer, deployed S/N 2901
		+	* Think I figured out the thermal conductivity problem.
		+	* In-memory reset of snow depth offset
		+	** SR50A1 = 159.7
		+
		+	Additionally:
		+	* I think A & C precip are probably the highest quality (most stable stands).
		+	* C net radiation will need a fix for the stripped out screw next visit
		+	* Averaged 30 minutes per site.
		+	* Ended up not having wheelbarrow access but we had no problem carrying things out.
