ws pullossa iso paine (1.0). Johtunee siitä että putkea leikatesssa se meni umpeen eikä auennut kunnolla ruuvilla. Tuomas tuo mukanaan kunnon työkalut.??? 27-29.5.2011 New main power cable to cabin. => Big pump of LGR started OK. Flux measurements are running from 27.5. Error in ini-file => good CH4 flux data starting 28.5 Pressures T1 122 T2 75 C1 120 C2 102 WS 96 PPFD and PPFDrefl seem to be wrong way - PPFDrefl is higher. Tuomas changed them last time. We changed the parameters inpqBarlog.ini(air) =>Now the PPFD is the actual downward radiation (tested by covering the sensor) PPFDrefl is reflected but if Tuomas chanaged the sensors then the calibration coefficients may be wrong. Discuss. CO2 calibration 30.5.2011 about 01:00 went well. The zero was very stable so we zeroed Licor with zero gas and spanned it with caf and ws values. co2 zero 15.3=>0 span 393=>402 h2o zero 0.3=>0 span 6.7=>7.1 Soil thermometers at -5 and -20 were broken, new ones installed and located close to main air temperature => will be installed properly when soil melts Concentration system is ok I guess. Kalvot vaihdettu pitoisuus Thomasiin vuo Thomasiin löytyi uusi sarja, muttei vaihdettu =>vaihdetaan kesällä tai syksyllä. Muistettavaa Hyttysuoja LGRään jatkojohto LGRän pumpulle - pumppukoppa ei nyt varjossa ja muutenkin vähän huonosti. tikkaat (licorin huolto vaikeaa) Masto paremmin kiinni tai uusi masto tilalle. Matt O:lle viime vuoden kesän lämpötiloja Albedoräkit yhteistilauksella, jos porataan tundraan niin porataan samalla eddymasto Koppi mäelle: Taneil ja Maxtash ok, Taneil halusi tehdä siitä uuden hankkeen => uusia hankkeita haettaisiin tietyllä protokollalla Tue Mar 27 13:17:53 GMT 2012 Move old data (prior 01.01.2012) to Archive folder -Dmitry Apartsev 14-17 May 2012 The pump for flux LGR don't start. After some hours of pluging and un-pluging and measuring voltages it started after all. Then found out that the hard disk of the LGR is broken (Kernel panic + error warnigs about hd => Juha told that the meassages mean that hd is broken. New sonic installed (2007-0001 tms). RS232 output-plug was is female whereas it was male in the old one => can't connect to ADAM directly (needs null modem cable and 2 male-male gender changers.) => started workin at 11.00 but the heating was of and the data flow stopped at some point => heating turned on (on 16 May , 02.30?) Cryo cooler turned on for concentration LGR. (tubings were also changed to go through cooler). Checked the connections - no leaks. Changed the working gas cylinder (STPB cylinders). The old one has now about 20 bars. Licor calibrated CO2 z 33.6=>0 s 396=>402 H2O z 0.86=>0 s 3.35=>3.6 (zero gas from the cylinder at cabin 16 May 02:00, span calibrated agains the concentration LGR at 17 May 00:30) New sensor-head changed for Vaisala Humicap New scrubber-pump for Licor (the old one still works ok, it was left on the LI7000) Opened LGR with Vova to locate the hard disk. Vova is going to change it, if we get new HD to Tiksi. David changed one membrane in Thomas pump - that was the last one. New thermostat installed to GHG/Aerosol-rack. It was set to 27 C and it seems to be working ok. Fixed solenoid status of O3 analyzer (USA) and connected it to new computer for remote control. David+Eija downloaded the data to USA-PC (and the connection worked fine). Ogren tube in the pump cabin is closed by jeesusteippi. Concentration inlets in the tower looked fine. Pressures for different calibration gases tuned to match sample pressure 577 (or slightly higher). [Edit tiLGR.run => write calibration time to the 3rd last line (hhmm=1242) => you get ws, c1, c2, t1 for 6 min each, ask Juha for easier way] Cylinder pressures: ws=57, c1=110, c2=77, T1=113, T2=122 (ws old 20 => consumption 75bar/year?) For next time Jatkojohto lgr pumpulle Tikkaat Kalibrointi systeemi (pulloon pa-venttiili) span pullo??? sopivat liittimet nippusiteet magnesium per+ sodalime (victor hankkii) varatietokone (testataan cabinilla) working gas Thomasin kalvot superlähetykseen työkalupakki lgr pumppu licor pumppu varalle? pitoisuus pumput??? Muuta muistettavaa vova ostaa kovalevyn, lähetä tiedot maksettu 3000r käteen (pyydä kuitti) ei hyttyssuojaa - vova joskus kesäkuun lopulla vova paikalla heinäkuussa => ghgn opiskelua?? Vova sanoi, että Tiksistä saa pöytäuunin , voiko mikrolla kuivattaa maanäytteitä, testaa uudelleet havut 21 July 2012 Cylinder pressures: ws=63, c1=109, c2=75, T1=112, T2 (kiinni)=122 (ws pullo oli ollut se tyhjempi (5124210 nyt 10 bar) - vaihdoin toisen pullon 5125097 ja siinä 63bar) Pitoisuus LGRn johdot OK. Puhallustestissä ei merkkejä vuodoista. LGRn kovalevy tyhjennetty ja talteen kesä 2012. Tyhjennetty kama saattoivat kuitenkin jäädä roskikseen. PCn kovalevyllä reilusti tilaa (14% käytetty) Vuolicoriin vaihdettu suodatin ja lisätty hyttyssuoja. LGRn pumppu-boxi vietiin kopin taakse. Licorin pummpu siirretty sinne. CMP3 reflected näyttää oikein kytketyltä, mutta data on ihan sekoa. => Maiju peitti kuvun ja sieltä tuli arvoja 10..160. 25 Sep 2012 Tuomas and Eija in Poljarka Tuomas calibrated Licor zero was 34ppm (CO2) and 0.93mmol/mol (H2O) Zeroed using MGO zerogas. CH4 fluxes have been small and radom without clear lag. There was flow. I tooked mosquito protection nets away. Maybe one of the Swagelocks was loose. Tightened Eija is adding heating and insulation to the aerosol inlet stack. 30 Aug 2013 -Set of leak-tests performed on LI7000. Leak was founded on the inlet SWAGELOK to reference cell. It was not tight enough. Fixed that and changed the scrubber chemicals. -Tried to change Flux system to new computer. There was only 2 COM-ports left. Tried to move BarLog.wet to old computer. It did not start working. Will contact Juha - New program to Dry1 QML - fixed soil moisture problem - Wet OML: Soil temperature profile on a stick -10, -20, -40 -5 cm at the same point but not on the stick Water table depth on the stick at -20cm Soil heat flux plate as it was (-7 cm) Soil humidity in surface moss (in -3 cm) Another soil temperature in -5 and soil humidity in -5?? left as they were. - WTD at the river tied to a metal plate (kulmarauta). The electronic box at the river bank installed 20 cm from the soil - Pressure of T2 gas (valve 4, CA06348) was over 1000, Changed to 570. - Tried to change GHG fluxes from Advantech to new Dell, but there are not enough RS-ports (4 Barlogs dry, dry, wet and CAF, METEK and FD12) Tried to change WET-log to Adva, but it didn't work - wrong Python version or something else) - Active layer depth was measured on the vegetation grid: 8 dir, 0-100m every 5 meters, 100-200m every 10 meters. - LIcor was calibrated on 2 September 7.35 CO2 z 48=>0 s 383=>397.7 (pitäisi olla 395.77 H2O z 1.23=>0 s not calibrated CO2 z -1.8=>0 s 398.3=>395.77 H2O z OK s 9.0=>10.0 - Some reflectance spectras were taken with HH2 (25-100 m on the vegetation transects) - Soil people from Sweden and Denmark visited site, dug some holes to estimate visually soil structure and active layer depth - Advantecin Flux/raw tyhjennetty Archiveen (30.5.2013 asti) - Cylinder pressures ws=182, c1=30, c2=32, T1=90, T2=115 - Flux LGR was packed and we (Mika and Viktor) will take it to Yakutsk. Yakutian hydro will keep it until FMI arranges the transport by DHL. Copied whole home/measprogs to usb-stick Could not create symlink /media/kingston/measprogs/www/tiksipylib.
