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

LEO CNR4 Center Bay West Sensor Re-purposed

The west most CNR4 Sensor (LEO-C_10_-2_0_CNR4) was removed from the Center Bay mast on Thursday August 8th between 8am and 10 am by Aaron Bugaj.

This sensor is temporary being used in the West bay for a remote sensing experiment.

LEO CSAT3

There is no LEO CSAT3 for the East or West bay installed due to damage/maintenance.

Data logging to the East and West bay have been stopped as of 7/25/2019 8:25am.

LEO Center Load 14_-3_0 cells 3130 channel swap

load cell 14_-3_0 signal channel was swapped to see if the noise was less prevalent in the other channel.

LI7000 missing data

LI7000 configuration was changed unknowingly, subsequently, we have a long time period of lost data.

Data since 2017-11-20 11:20:48.

The issue was rectified on 2019-03-13 22:23:05.

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. 

10-4-2018 LEO Tipping bucket recalibration

We have recalibrated the LEO Novalynx tipping bucket. 10/4/2018 10:45pm data set onwards are using the new calibration values.

6/4/2019: The following shows the updated calibration coefficients used on the Novalynx.

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.

Irrigation and seepage flowrate changed to incremental

The volume calculations for the irrigation (EX81) and seepage (Novalynx,PE102) have been update to show the change in volume between each logging time period (15 minutes) instead of cumulative volume.

Data from 9/6/2018 1:45pm onward reflect these changes.

Expect some data interruption on 9/5/2018 and 9/6/2018.

**Fixed irrigation incremental logging on 9/11/2018 11:00am. Please disregard data recorded from 9/11/2018 8am to 11am.

***EX81 incremental liters/sec can also be found on the Labview DSM.

Decagon SDI12 sensor Firmware upgrade

We have upgraded the firmware on the Decagon 5TM (V4.00) and MPS2 (V3.86) to help prolong the life of the embedded sensors on the hillslopes.

The main features of the new firmware upgrades:

1. Only SDI12 addressed as Zero will go to awake state and send sensor read on during initial power on. All other non-zero addressed sensors will go to quiescent mode.
2. Help sensor be more robust to brownout conditions.

The following dates were the serials of events that occurred when the aforementioned sensors were powered off or on for the upgrades.

• 2/27/2018 - West hillslope powered off.
• 2/28/2018 - Center hillslope powered off.
• 3/1/2018 - West hillslope powered on.
• 3/2/2018 - Center hillslope powered on.
• 3/6/2018 - East hillslope powered off.
• 3/13/2018 - East hillslope powered on.
