<p>137.229.91.109: </p> <hr /> <div><br /> Head up June 7th, 2016<br /> ==install new evap pan==<br /> *leak test (marine epoxy in case of leaks. should be up in the EDC office)<br /> *clean out bottom<br /> *field calibrate<br /> <br /> Fill pan partway with water, measure height with ruler in mm<br /> Measure voltage by reading the EvapLevelTemp variable on the program<br /> Add more water, measure water depth in pan<br /> Measure voltage<br /> Calculate multiplier and offset using y = mx+b<br /> m(multiplier) = (height1-height2)/(voltage2-voltage1)<br /> b(offset) = height1-(m*voltage1)<br /> <br /> ==calibrate precip==<br /> Tipping bucket<br /> *fill bottle to line, use smallest orifice, do this 3 times<br /> *should be 30mm per bottle, so 90mm total<br /> *change multiplier in program if necessary <br /> <br /> Pluvio accuracy test<br /> *received software in ftp from ott (on my fancy laptop, need to transfer to toughbook)<br /> *need usb cable<br /> <br /> ==Brie Helps with==<br /> *swap in fancier wind sensor 5108-45-12M<br /> ::shouldn't need to re-align if don't move he orientation ring<br /> *swap out HMP155s<br /> **write down which height is which SN<br /> *download garden cam images<br /> ** bring replacement batteries<br /> ** to turn off: press and hold organge power button until 3 beeps and green LED turns off<br /> ** remove drive, download and clear images on computer<br /> ** to turn on:press and hold organge power button until green LED lights up. after a few sec beep twice. green LED every 15 sec indicates normal running. if any other beeping or lights, consult manual<br /> <br /> ==additional tasks==<br /> *wire junction to split all instruments needing 12V from logger<br /> *swap out quantum sensors<br /> **bring mini wrench to replace them<br /> **&lt;s&gt;figure out what the connection is like at toolik&lt;/s&gt;<br /> **&lt;s&gt;change calibration constant?&lt;/s&gt;<br /> *remove old radio<br /> *get field books from Brie<br /> *swap CNR4, change program constants<br /> *install new barometer, change program constants<br /> *level radiometers + tipping bucket<br /> *Take down auxiliary snow station<br /> **get data off of logger, wind up power and ethernet, etc<br /> <br /> == take photos of sensors without pics on instrumentation site==<br /> *HMP155<br /> *wind sensors<br /> *snow dept<br /> *barometer<br /> *evap pan<br /> <br /> ==program changes==<br /> *evap pan calibration<br /> *possible tipping bucket calibration<br /> *possible pluvio calibration<br /> *&lt;s&gt;UVA+UVB corrections. UVA:0.0221, UVB: 0.00178 (per Lija's email)<br /> *barometer mult and offset changes (+85 to offset for elevation difference)<br /> *CNR4 constants<br /> ::LW up: 7.51<br /> ::LW down: 8.24<br /> ::SW up: 16.77<br /> ::SW down: 14.82&lt;/s&gt;<br /> *we zero out the CMP6, but not the CNR4. reconsider?<br /> <br /> ==get SN of all instruments/loggers on google sheet==<br /> *datalogger,mux, radios, nl__<br /> *both wind sensors,cmp4, cmp6, evap gauge, precips<br /> *basically everything<br /> <br /> ==To change on instrumentation website==<br /> * pluvio is actually version 2<br /> * lake temp measurement<br /> * barometer<br /> * ask ed to put 2015 met report up<br /> <br /> ==to bring==<br /> *laptop + charger<br /> *field laptop + charger<br /> *tipping bucket calibration box<br /> *gloves, hat(warm and sun)<br /> *tools (level, compass, small wrench for quantum) <br /> *wire junction<br /> *hiking boots,rubber boots,running shoes<br /> *field book, regular notebook<br /> *usb cable for pluvio<br /> *batteries for garden cam<br /> *measuring cup set for leveling UVA and UVB sensors<br /> *cookies for brie<br /> *instruments<br /> **anemometer<br /> **CNR4<br /> **Two HMP155s<br /> **baromter<br /> **quantum<br /> <br /> ==to purchase==<br /> *action packers<br /> *AA batteries<br /> *scrubby for the evaporation pan<br /> <br /> ==should have had==<br /> *electrical tape<br /> *snips<br /> *crimper (where did it go?)<br /> *rectangle level<br /> *larger crescent wrench<br /> *zip ties<br /> *2 crossarm mounting kits for wind sensors<br /> *mesh for shield for pluvio<br /> <br /> ==accomplished==<br /> June 6, 2016<br /> *swapped both HMP155<br /> *swapped 5108 for 5106. the crossarm had rotated. brie re-levelled it and secured it with better crossarm mounting bracket (need to purchase another). and consider moving the bar next time we swap a sensor.<br /> *downloaded garden cam images, cleared flashdrive, replaced upper batteries, need to replace lower ones.<br /> *emptied pluvio<br /> **pluvio software WORKS when connected to pluvio! calibrate tomorrow<br /> <br /> ==Tomorrow==<br /> *blue mesh/tarp for pluvio?<br /> *find a weight for the pluvio</div>
