Ovaj sustav koristi US EPA za pretvaranje očitanja sirovih zagađivača, izraženih u µg/m3 ili <i>ppb</i> , u AQI (skala od 0 do 500).

Razlog za ovo usrednjavanje je taj što <a href='http://airnow.gov/index.cfm?action=aqibasics.aqi'>AQI ljestvica</a> navodi da je svaka od razina zdravstvene zabrinutosti (tj. dobra, umjerena,... nezdrava...) važeća pod 24-satnom izloženošću <sup><a href="#nowcast-footnote-1">[1]</a></sup> .

Dakle, prošlog vikenda, kako je zagađenje zraka u Pekingu postalo stvarno nisko - zahvaljujući jakim sjevernim vjetrovima, iskoristili smo ovo vrijeme kao priliku da napravimo pauzu za održavanje... na samom monitoru Dylos.</p> <p>Razlog je taj što, čak i ako je monitor Dylos definitivno dobro dizajnirana i konstruirana oprema (mi zaista to mislimo), možda nije tako dobro zamišljen da podnese teško epizodno zagađenje zraka u Pekingu.</p> <p>Sve je počelo nakon što smo primijetili da korelacijski grafikoni između Dylosa i BAM monitora pokazuju neke sustavne znakove izravnavanja iznad 38 000 čestica (≥0,5µ). Ovakav simptom zasićenja može biti posljedica unutarnjeg uskog grla dotoka zraka, koje mogu uzrokovati "zasićeni" zračni kanali. U vrijeme velikih zagađenja, ova pojava je potpuno normalna zbog velike količine čestica koje moraju proći kroz zračni kanal.</p> <p>Dakle, nije iznenađenje, nakon otvaranja Dylos monitora, potvrdili smo da su unutarnji zračni kanali definitivno zasićeni, nakupljanjem prašine tijekom posljednjih 50 dana:</p> <center> <img src='/images/dusty-dylos-monitor-1.jpg' height=350 border=0 style='max-width:100%' title='Dust accumulated in the Dylos air particles counter front sensor area (laser and photodiode sensor)'>   <img src='/images/dusty-dylos-monitor-2.jpg' height=350 border=0 style='max-width:100%' title='Dust accumulated in the Dylos air particle counter back air channel area'> <br> -<i>Beijing dust impact on the Dylos air particle counter internal structure</i>- </center> <p>Rezultat čišćenja unutarnje strukture, korištenjem fine četke, proizveo bi zapanjujuću količinu prašine - i to nakon samo 50 dana eksperimenata na otvorenom.

Iz donjeg grafikona, koji prikazuje mjerenja prije i poslije čišćenja, zona označena brojem <b>(2)</b> pokazuje vrlo dobru sličnost (korelaciju) između BAM-a i Dylosa. Ali, u uvjetima velikog onečišćenja, još uvijek postoje dosljedni znakovi izravnavanja (odstupanja u mjerenju), kao što je istaknuto brojem zone <b>(1)</b> i <b>(3)</b> . Čini se da je odstupanje manje gore nakon čišćenja (zona <b>(3)</b> ) nego prije (zona <b>(1)</b> ). Kontaktiramo tvrtku Dylos kako bismo ih konzultirali o ovom fenomenu izravnavanja, a kasnije ćemo ažurirati ovu objavu.</p> <br> <br> <center> <a href='/sensor/beijing/sanlitun/'> <img src='/images/dylos-monitor-vs-bam-monitor-correlation-impact-after-cleaning-1.jpg' width=80% max-width=930px border=0 style='max-width:100%'> </a> <br> <i>(Click on the picture to open the real time version)</i> <br> </center> <center><br>-<svg xmlns="http://www.w3.org/2000/svg" width="28" height="28" version="1" viewBox="0 0 26 26" enable-background="new 0 0 26 26"><path d="M 15.65625 -0.03125 C 14.280846 -0.03760636 12.828752 0.09254274 11.3125 0.40625 C 8.28651 1.0323169 5.7746616 2.1709106 3.96875 3.59375 C 2.3885774 4.8387345 1.3097647 6.3321654 1.0625 7.96875 A 1.0001 1.0001 0 0 0 1 8.40625 C 1 8.4709766 0.99753847 8.5296394 1 8.59375 C 0.99939321 8.6245955 1 8.6565744 1 8.6875 C 1.0067678 8.8049913 1.0164368 8.9159604 1.03125 9.03125 C 1.0536237 9.2185949 1.1014372 9.4156735 1.15625 9.59375 C 1.4590854 10.826485 2.2046296 11.91918 3.21875 12.78125 C 4.0779092 13.511593 5.1369309 14.083861 6.3125 14.53125 A 1.0001 1.0001 0 0 0 6.53125 14.9375 C 8.1339345 16.910035 12.101162 19.118434 18.1875 18.59375 A 1.0043849 1.0043849 0 0 0 18 16.59375 C 14.906411 16.860439 12.500325 16.269357 10.78125 15.5 C 14.30154 15.772761 18.245209 15.070028 21.71875 12.96875 A 1.0021949 1.0021949 0 1 0 20.6875 11.25 C 16.887924 13.548509 12.317006 14.000584 8.78125 13.21875 C 8.6725971 13.194724 8.5753958 13.151278 8.46875 13.125 C 10.108287 13.189898 11.88322 13.060799 13.6875 12.6875 C 16.718701 12.060355 19.36029 10.886006 21.21875 9.4375 C 23.067114 7.9968631 24.272087 6.1533076 23.875 4.21875 C 23.8732 4.20861 23.8769 4.197602 23.875 4.1875 C 23.513143 2.2541955 21.685558 1.0369822 19.4375 0.4375 C 18.307598 0.13619269 17.031654 -0.02489364 15.65625 -0.03125 z M 15.65625 1.96875 C 16.883971 1.97489 18.004902 2.1263073 18.9375 2.375 C 20.802695 2.8723854 21.754612 3.7133252 21.90625 4.5625 A 1.0001 1.0001 0 0 0 21.9375 4.625 C 22.12047 5.4788616 21.54154 6.6735055 20 7.875 C 18.45846 9.0764945 16.081299 10.145895 13.3125 10.71875 C 10.546306 11.291066 7.7660826 11.269646 5.8125 10.78125 C 4.8357087 10.537052 4.0847823 10.157122 3.625 9.78125 C 3.3682882 9.5713881 3.1893221 9.3858538 3.09375 9.1875 C 3.0413411 8.9743851 3.0082478 8.7545393 3 8.53125 C 3.0633474 7.4789308 3.7648202 6.2771492 5.1875 5.15625 C 6.6815884 3.9790894 8.91349 2.9489331 11.6875 2.375 C 13.071248 2.0887073 14.428529 1.9626064 15.65625 1.96875 z M 15.96875 3.65625 C 14.93792 3.617106 13.843984 3.69192 12.71875 3.90625 A 1.0001 1.0001 0 0 0 12.6875 3.9375 C 9.8940815 4.582135 7.6159262 5.8506824 6.5625 7.5625 A 1.0001 1.0001 0 1 0 8.25 8.625 C 8.7942179 7.740646 10.701734 6.434394 13.09375 5.875 C 13.10453 5.87295 13.11421 5.87702 13.125 5.875 C 15.064267 5.5112859 17.031887 5.6468794 18.03125 6.03125 A 1.0040202 1.0040202 0 0 0 18.75 4.15625 C 17.952461 3.8495042 16.99958 3.6953943 15.96875 3.65625 z M 9.15625 17.59375 A 1.0001 1.0001 0 0 0 8.5625 19.25 C 8.5625 19.25 11.033033 22.015963 15.53125 21.90625 A 1.0004882 1.0004882 0 1 0 15.46875 19.90625 C 11.766967 19.996537 10.0625 17.9375 10.0625 17.9375 A 1.0001 1.0001 0 0 0 9.15625 17.59375 z M 8.125 20.1875 A 1.0001 1.0001 0 0 0 7.40625 21.65625 C 7.40625 21.65625 8.6869767 23.974979 11.65625 24.09375 A 1.001098 1.001098 0 0 0 11.75 22.09375 C 9.7192733 22.012521 9.1875 20.75 9.1875 20.75 A 1.0001 1.0001 0 0 0 8.21875 20.1875 A 1.0001 1.0001 0 0 0 8.125 20.1875 z M 7.59375 23.0625 A 1.0001 1.0001 0 0 0 7.4375 23.09375 A 1.0001 1.0001 0 0 0 6.9375 23.34375 C 6.9375 23.34375 6.19375 24 5.09375 24 A 1.0001 1.0001 0 1 0 5.09375 26 C 6.99375 26 8.28125 24.84375 8.28125 24.84375 A 1.0001 1.0001 0 0 0 7.59375 23.0625 z" color="#000" ></path></svg>-<br><br></center><div style='display:inline-block;width:50%;border-top:1px solid black;margin-bottom:20px;'></article><article><div><a href='https://aqicn.org/faq/2013-09-09/revised-pm25-aqi-breakpoints/hr/' class='faqlisttitle'><span>Revidirane prijelomne točke PM <sub>2.5</sub> AQI</span></a></div><div style='height:1px;background-color:#aaaaaa;width:80px;margin-top:5px;'></div><small style='color:#888;'>September 9<sup>th</sup> 2013</small><div><small>https://aqicn.org/faq/2013-09-09/revised-pm25-aqi-breakpoints/hr/</small></div><div style='height:1px;background-color:#aaaaaa;width:80px;margin-top:5px;'></div><div class='entry-content;' style='min-height:250px;cursor:pointer;' onclick='window.location="https://aqicn.org/faq/2013-09-09/revised-pm25-aqi-breakpoints/hr/"'> <p>Iz nekog povijesnog razloga, formula za pretvorbu AQI koja se koristi za neke gradove u projektu Svjetskog indeksa kvalitete zraka nije koristila <a href='http://www.epa.gov/airquality/particlepollution/2012/decfsstandards.pdf' target=_>ažurirani standard EPA PM <sub>2.5</sub> iz 2012</a> .

To je profesionalna oprema, a ujedno i jedina službena oprema koja se koristi za praćenje kvalitete zraka u Kini, SAD-u i većem dijelu svijeta. Najpoznatiji proizvođač je američka tvrtka <a href='http://www.metone.com/' target=_>Met-One</a> .</p> <p>Princip rada BAM-a prilično je jednostavan: mjeri smanjenje broja beta čestica (elektrona) propuštenih kroz tanki sloj čestične tvari (PM). Kako se debljina PM sloja povećava, manji broj beta čestica može proći.</p> <br> <br> <center> <a href='http://alg.umbc.edu/umap/bam_index.html' target=_> <img src='/air/faq/images/bam.jpg' width=500 style='max-width:100%' border=0> </a> </center> <br> <br> <p>Jedini problem s ovom vrstom BAM opreme je cijena, procijenjena na 120K CNY (15K EUR).

U Tajlandu postoji 21 automatska (tj. s očitavanjem po satu) postaja, ali nijedna od njih ne daje podatke o PM <sub>2,5</sub> .
