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.
Higher Infiltration Rate
On February 1, 2022 the standard bi-weekly rain was altered to explore the impact of the developed surface crust at higher infiltration rates.
The standard schedule is: rain from 7:45am to 2:45pm with Multi2 at approximately 13mm/h.
The plan was to cut the rain one hour short and rain the previous hour at double intensity (7:45am-12:45pm with Multi2 at ~13mm/h and 12:45pm-13:45pm with Multi1 and Multi2 at ~26mm/h).
Overland flow started shortly after switching to the higher infiltration rate. Rain was stopped at ~13:03pm.
As of right now, the rain rate should not exceed 13mm/h.
Short LEO rain
On 3/8/2021, the standard bi-weekly rain from 7:45am to 2:45pm was cut short at 1pm.
This was done to prevent our VFD pumps from running dry as there was insufficient water in the main LEO irrigation tanks.
The auxiliary tanks water was not pumped into the main tanks early enough.
LEO mast kept raised short term
To facilitate various work on the hillslope and due to lack of personnel, the LEO masts have been kept raised since 6/8/2021. This is a short term measure.
Center Bay CSAT3 Removed and Stored
The CSAT 3 instrument was removed by AB on 12/20/20 and stored in a box with the two other CSAT's above the discovery room (in the attic).
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.
LEO East SDI12 5TM and MPS2 power supply failure
Due to a 5V power supply failure in the P02 enclosure and the failure was not caught early, LEO East SDI12 5TM and MPS2 are not available.
The power supply failed 10/8/2020 3:00 am to 11/5/2020 10:30am.
