Quick notes about needed maintenance

We replaced wiper motors for both 68 and 61 in preparation for CWEX-13. Mike contacted Welly about 61 pump not working at same time. 3-pin pump trigger not behaving.

61: Wiper works, Pump hasn't worked since CWEX-13; problem is in internal box. Neither internal nor external pumps work. Could trigger the pump and observe electronics via multimeter (may need oscilloscope).

68: Wiper works but is finicky. Rubber is stiff, gets caught on glass lip. Gears slip on the mechanism.

49: Similar to 68. Needs new wiper blade.

Locations of the WC-V1s at the BAO

Here are the GPS coordinates for the Windcube V1s at the BAO site. They were installed on 1 July, 2014.

Windcube 61: 40.05118°N, 105.00544°W
Windcube 68: 40.04698°N, 105.00315°W

LUMEX status and current IP addresses

LUMEX Notes and Issues:

- WC49 is still deployed at the NWTC, near the M5 met tower, for intercomparisons with UAV flights
- WC68 is currently deployed SE of the BAO tower to provide a virtual tower for comparison to the Dual-Doppler measurements from NOAA's HRDL and UMBC's 200S
- WC61 (NCAR) is currently deployed at the NW guywire of the BAO to quantify heterogeneity across the BAO site (provide error bars for the Dual-Doppler work)

Issues:
- WC68's wiper motor is not working
- WC61's fan is not working (due to a short-circuit) although the temperature measurements is still working and can cut power in case of overheating
- WC61's pump seems not to be working

Useful information:
WC49: 129.175.131.3:1266
WC61: 129.175.131.7:1266
WC68: 129.175.131.8  

WC68 lives again

After swapping out the stage motor on WC68 it is now operating normally.  For now it is co-located with WC49 on the 4.0 pad at the NWTC.

WC49 transformer failure

While checking on our instruments today (2014/5/21) I noticed the power transformer on WC49 was not providing power to the LIDAR.  For further diagnosis I swapped the WC68 (not operational) transformer to feed into the WC49 port and then removed the WC49 transformer.  Everything started up as expected with the swap.

The internal WC49 transformer fan was running while it was plugged in but insufficient power was getting to the LIDAR.  I will post an update when I know further information.


Update:  The transformer seemed to be operating normally when tested in Boulder.  It has been providing power to WC49 for a couple weeks now without any issues.

Covered windows and failed stage motor

From ~8:30 to 10:45 on Friday November 8th both the WC61 & WC68 windows were covered for a diagnostic test (Clara knows about the details).

WC68 was also showing signs of a failed stage motor.  Further investigations hope to pin point when the system failed.


Minor update:  All three windcube covers were removed and place in the 3.1 shed along with the shipping boxes, wooden stands, and stand hardware.

LIDARs and Radiometer back at NWTC

On Monday September 9th WC49, WC61, WC68, and the CU Radiometer we re-deployed at the NWTC.

Instrument	NWTC Location	Latitude (dd.ddddd N)	Longitude (dd.ddddd W)
Radiometer	4.1 Pad	39.91058	105.22350
WC49	3.1 Pad	39.91122	105.22605
WC61	4.1 Pad	39.91061	105.22349
WC68	4.0 Pad	39.91194	105.22252

The radiometer shipping box is located in the 4.1 data shed.  All of the LIDAR shipping boxes and wooden field stands are stored in the 3.1 data shed.
