(also see:)
2-03-2014
- Modified new WS4 file (original data in WS4_140115_orig.dat):
- Changed errors (6999, -6999) to NaN
- Removed lines that were clear errors and changed dates back to 2013/14 (lines 174-end)
- Modified new WS6 file (original data in WS6_140115_orig.dat):
- Changed errors (6999, -6999) to NaN
- Added a column filled with 6 that is missing (a glitch in the new program).
- Removed a day that had a duplicate record (day 325)
- Removed lines that were clear errors and changed dates back to 2013/14 (lines 176-end)
- Plotted the data collected on 1/11/2014 and 1/15/2014
- WS1 (in the garden)
- There was a power outage on day 341 (Dec 7, 2013) and all data is missing after that.
- T/RH = new sensor seems to be working fine
- Wind sensor 1 = still not working
- Wind sensor 2 = ok, and this has windspeed and wind direction
- Rain gauge = ok
- PAR = ok (ten minute only)
- Battery = ok? I suspect the battery is not functioning because nighttime periods are not recorded (no solar panel input?)
- WS2 (by the reservoir)
- T/RH = ok
- Wind sensor = New sensor working fine
- Rain gauge = still ok
- Battery = losing capacity, low and erratic voltages - needs to be replaced.
- WS4 (halfway up canyon)
- There was a power outage that reset the date around Nov 19, 2013 and it looks like data resumed a bit in early Jan (2014).
- T/RH = ok
- Wind sensor = OK
- Rain gauge = not working.
- Battery = losing capacity, low and erratic voltages - needs to be replaced.
- WS6 (top of Parleys fork)
- There was a power outage that reset the date around Dec 3, collection resumed, then stopped around Jan 1, 2014.
- T/RH = ok
- Wind sensor = ok
- Rain gauge = ok
- Battery = losing capacity, low and erratic voltages - needs to be replaced.
- TO DO:
- Check WS1 and replace battery (probably)
- Fix WS6 program (missing fourth column in data output should be WS #)
1-20-2014
- Downloaded data from all storage modules and uploaded to Dropbox
- Storage modules are cleared,tested, and have programs loaded.
1-15-2014
- Pulled storage module from WS4 and WS6
- WS 4 initially seemed to be unresponsive, but after testing voltage it again seemed fine.
- Set the clocks for both.
- All 4 stations have modules with the program loaded in location 8.
1-11-2014
- Pulled storage module from WS1 and WS2
- WS1 seemed to not be collecting data at the time, so I reloaded the program and it then seemed alright.
7-6-2013
- Replaced wind sensor at WS2 with a replacement from an Ehleringer storage cabinet. Seems to work fine (Met One 014C).
- Sensor with the broken bearing was labeled and put back in the Ehleringer cabinet where the replacement came from.
6-7-2013
- Replaced T/RH sensor on WS1 with an HMP45AC that susan found.
- I don't know much about this sensor (when it was last calibrated, etc.), and I used the standard multiplier and offset (in Campbell manual).
- Uploaded the new datalogger program to read this sensor - seems to be working
- The new program is in the project Dropbox (130606 version).
- Swapped the storage module to get data from 5-23 to today.
- The file for this period is in the Dropbox, and the data haven't been added to the aggregated files yet.
5-31-2013
- Visited WS1
- The Vaisala HMP35 is broken - one wire lead for the thermistor is sheared off.
-
Temporarily put an old HMP35 (found at garden) on WS1 and removed the current one for inspection.
-
Visited WS4 & 6
- Installed new storage modules
- Transferred datalogger programs from new modules to dataloggers
- Reset clocks
- Data is being collected again at these sites, and future power outages shouldn't cause a problem (programs are in location 8 in the SMs).
5-29-2013
- Changed the date for all WS6 data files (that I have collected)
- I did this based on storage module dates - so I know the start/stop dates for each file
- As usual - there are
_orig
files in the directory that haven't been changed - Plotted the data collected on 5-3 and 5-23
- WS1 (in the garden)
- There was a power outage that reset the date over the winter - I fixed this in the datafile (and there is a
_orig
version saved). - T/RH = Seems to have broken on 1-5-2013. It is reading a negative number all the time
- This affects the vapor pressure measurements also
- Wind sensor 1 = still not working
- Wind sensor 2 = ok, and this has windspeed and wind direction
- Rain gauge = ok
- PAR = ok (ten minute only)
- Battery = ok? (:!: This is also reading ~-46 like the T sensor, but I checked it with a multimeter on 5-23-2013 and it was ok - ~13V)
- There was a power outage that reset the date over the winter - I fixed this in the datafile (and there is a
- WS2 (by the reservoir)
- T/RH = ok
- Wind sensor = Data are flat for the last 1-2 months. Dave E confirms that the sensor has frozen up (bearing?) and it will need to be replaced.
- Rain gauge = ok for the last year, though it looks like it had problems before that
- Battery = ok (still losing capacity, but voltage is > 12)
- WS4 (halfway up canyon)
- There was a power outage that reset the date over the winter
- Only a few days of data were collected - all sensors looked ok in this short time, except maybe the rain gauge.
- WS6 (top of Parleys fork)
- There was a power outage that reset the date over the winter.
- Only a few days of data were collected, and data look ok in this short time.
- The date is wrong for this WS, and the last few datafiles - this was adjusted using dates of collection.
- :!: NOTE that there is a
_orig
file with unchanged data (datalogger dates say 2004).
- TO DO:
- Swap storage modules for WS2-6 with modules that have programs loaded in location 8.
- Load these on to 4 & 6 after they are swapped
- Test and replace T-RH unit on WS1
5-23-2013
- Revisited WS1 and WS4.
- Cut the lock off of WS1 (never found the key), and swapped the storage module.
- There are some problems with WS1 data.
- There was a power outage that reset the date over the winter - I fixed this in the datafile (and there is a _orig version saved).
- Data from the temperature sensor is bad and it is affecting vapor pressure measurements.
- The battery voltage is reading ~-46 - this may be related to the temperature problem.
- Checked the WS4 battery and solar panel voltages and downloaded the running program from the CR10.
- Battery and solar panels seem fine.
- The running program looked invalid - was probably erased in a power outage.
- REMEMBER - When swapping out modules, store the datalogger program in location 8 (see here).
5-3-2013
- Visited WS2, 4, & 6 to swap storage modules
- WS4 & 6 were not collecting data, and appeared to have lost power (and their programs)
- The data collection stopped soon after the fall 2012 visit.
- WS6 Still thinks it is 2031 - need to reset clock
- WS2 seems OK.
- WS1 was was inaccessible because the key was missing from the usual place.
1-8-2013
- Went to WS1 (Garden) and downloaded all data (Austin needed early Nov. data)
- Reset clock on datalogger - it had reset itself to 4 years earlier for some reason. Date of this change was sometime after the last collection (early Nov).
11-2-5-2012
- Visited weather stations 1-4 and swapped out storage modules.
- Took photos and checked wiring.
- Plotted data
- WS1 (in the garden)
- T/RH = ok
- Wind sensor 1 = not working
- Wind sensor 2 = ok, and this has windspeed and wind direction
- Rain gauge = ok
- PAR = ok (ten minute only)
- Battery = ok? (:!: Big drop in voltage, but everything seems to be working ok - not sure I believe the drop)
- WS2 (by the reservoir)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = ok for the last year, though it looks like it had problems before that
- Battery = ok (still losing capacity, but voltage is > 12)
- WS4 (halfway up canyon)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = looks like my fix helped, but it may be down again
- Battery = capacity is better now, but there may be a bad connection and a slow decline in capacity.
- WS6 (top of Parleys fork)
- This datalogger is having problems, looks like a short may be resetting the date. Most of the data seems intact though.
- NOTE that I doctored the data file (using my best judgement) to remove bad data. There is a raw data file marked
_orig
on the data download site that contains the un-doctored data. Missing or removed data are marked as "NaN" in all other files. - T/RH = ok
- Wind sensor = ok
- Rain gauge = ok
- Battery = battery capacity back up to 12v? I think there must be a short somewhere.
4-9-2012 Plotted 4/4 weather station data today:
- WS1 (in the garden)
- T/RH = ok
- Wind sensor 1 = not working
- Wind sensor 2 = ok, and this has windspeed and wind direction
- Rain gauge = ok
- PAR = ok
- Battery = ok (losing capacity?)
- WS2 (by the reservoir)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = ok for the last year, though it looks like it had problems before that
- Battery = ok (losing capacity?)
- WS4 (halfway up canyon)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = still broken, but may have been fixed at last visit
- Battery = abruptly lost capacity (down to ~10V), seems to power the sensors though
- WS6 (top of Parleys fork)
- Datalogger needs time reset (thinks it is 2003)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = ok
- Battery = low capacity (down to 9-10V), seems to power the sensors though
4-4-2012
- Visited weather stations 1-6 and swapped out storage modules.
- Did some taping of wiring at weather stations 2 and 4 (insulation on wires is cracking)
11-28-2011 - Greg and Susan visited WS6
- Uploaded WS6_111122.dld program from the laptop
- Verified that all sensors were working - all were, including the T/RH and precip gauge.
- Replaced T/RH sensor shelter with a new one and realligned/reattached precip gauge.
11-21-22-2011
- SC32A jumper set as per CS instructions. It should be possible to connect to a CR10 with this in the field.
- Rebuilt WS6 program from Dropbox using Edlog (Document DLD File). The most recent file was called WS2_071030.dld. Leaving T/RH calibrations (multiplier and offsets) alone even though it is likely we will replace this sensor. May have to do a calibration of all sensors in spring.
- WS6_111122.CSI is now on Dropbox
- Went through calibration data on Dropbox - Looks like all T/RH sensors were calibrated (except maybe #4)in the recent past using a dewpoint generator.
11-16-2011 - Plotted data from all sensors in matlab to look at what sensors are working. This is what I found:
- WS1 (in the garden)
- T/RH = ok
- Wind sensor 1 = not working
- Wind sensor 2 = ok, and this has windspeed and wind direction
- Rain gauge = ok
- PAR = ok, though there is a weird seasonal jump in PAR (by about 300μmol m^-2^ s^-1^ in the middle of summer)
- Battery = ok (no charging problems)
- WS2 (by the reservoir)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = ok for the last year, though it looks like it had problems before that
- Battery = ok (no charging problems)
- WS4 (halfway up canyon)
- T/RH = ok
- Wind sensor = ok
- Rain gauge = broken for the last 1.5 years
- Battery = seems to be losing capacity over time and may need replacement soon
10-7-2011
- Was able to download data from all 3 returned storage modules (WS1, 2, & 4)
- See procedure here
- Uplodaded data files to project Dropbox
10-5-2011 - Susan and Greg visited WS6
- T/RH and rain sensors are both bent out of shape
- Station appears to have lost power and there is no program running.
9-30-2011 - Collected storage module from WS1 at around 5:30pm
9-27-2011 - Susan and Greg collected storage modules from WS2 & 4, did not reach WS6.
