LEO center SDI12 subsoil sensor offline

LEO Center SDI12 subsoil sensors when offline after 3/1/2022 at 9pm.

The power supply to these sensors was found to be dead.

It was replaced on 3/14/2022 around 12:40pm.

Since there was no power to the sensors, data at this offline period will not exist.

LEO CNR4 Center Bay reinstalled

LEO-C_10_-2_0_CNR4 was repurposed back in 8/6/2019 10:30am onwards to the West bay for a remote sensing experiment.

See previous note here, LEO CNR4 Center Bay West Sensor Re-purposed

It has been reinstalled back to the original LEO center slope.

*From 8/6/2019 10:30 am to 3/3/2021 10:15 am, LEO-C_10_-2_0_CNR4 does not have any data as it was physically removed.

DSC OS patching

OS security patching was applied starting approximately 12:15pm on 2/4/2021.

Patching was completed approximately 3pm on 2/4/2021.

Data during the time range is not available.

Missing data due to switch upgrade

DSC server was affected by switch SW upgrade.

5/13/2020 4 - 6 am is missing data.

Corrected center bay PE102 leak data

PE102 Center bay for the leak was wired incorrectly, hence, it was never recording properly since 2018 till Jan 2020.

Since this PE102 only measured the leak from the seepage, it only exhibited low flow rate and was never above the minimum flowrate of the PE102.

However, due to a recent accidental discovery of the seepage leak in the center bay with the -2 and -1 seepage locations clogged, it had increased the flowrate of the leak to a point that was greater than the Novalynx tipping bucket measurable flowrate and within the measurable flowrate of the PE102.

The Database has been updated with the corrected PE102 center bay leak flowrate.

1 sec/min Data logging Performance Issue

There was a performance issue with the main dsc.b2 server with generating log files for 1 minute and 1 second log files.

Affected time range: 9/11/2019 8:10 PM to 9/16/2019 10:40AM

PE102-038 East Bay -2 Swap

The PE102-038 in East bay -2 position was measuring about 1/2 of expected counts. Flowmeter from the +4 position in East bay was swapped with -2 position until a replacement is available. 

Added UV sensor to LEO-OWS

A SU-100-SS-L-20 was added to the LEO-OWS.

*Found that 15 minute moving average for the HMP60, SQ110, LP02, was incorrect and has been fixed.
Unsure if 15 minute moving averaged data before 9/26/2018 12:15pm is correct.

Tipping buckets LEO

Updated- 3/6/2019

West -1 NovaLynx tipping bucket was broken, Shell was replaced on 9/8/17. Calibration done and changed in DSM on server 9/11/17 12:45 to .033305 L/tip

East-2 NovaLynx tipping bucket was re-wired, possible bad connection creating spikes in data, will monitor over next rains and re-evaluate

1/15/19- Replaced reed switches on East Bay Nova Lynx +1 and +2 locations due to switch bouncing and noisy data. 

**The Nova Lynx proxy sensors have been rewired to eliminate the terminal block inside the tipping bucket enclosures. Rusting of the terminal blocks' terminals have been shorting the terminals causing noise. The voltage suppressor bi-directional diodes have been moved out of the rusting terminal blocks to the terminal blocks in the enclosure. Note that the terminal blocks were left inside the enclosures.

2/19/2019 - Rewired LEO East
3/6/2019 - Rewired LEO West. 3/13/2019 - LEO West leak tipping bucket

3/7/2019 - Rewired LEO Center bay

2016126100540 East +4 flow meter swap

On Dec. 5, 2016 from 13:45-13:55, Nate changed out the PE102-75 flow meter with a PE102-38. Looking at the raw counter data it seems to be working. This was a used ebay purchase. 

Data before this time used incorrect scaling factor (1000, instead of the correct 500 for a -75).

Scaling factor was not changed at this point, since the correct value is already in place.
