δημοσιεύονται στο <a href='/home/el/'>έργο World Air Quality Index</a> και αναρωτιούνται για τη διαφορά με τις τιμές που εκφράζονται σε άλλους ιστότοπους. Και αυτό είναι στην πραγματικότητα φυσιολογικό, καθώς οι αριθμοί, που ονομάζονται επίσης δείκτες ποιότητας αέρα (AQI), μπορεί να είναι πολύ μπερδεμένοι για αρχάριους. Το τελευταίο μήνυμα που λάβαμε είναι το εξής:</p> <blockquote> <p>Ελέγχουμε τον δείκτη ποιότητας αέρα για το Tianjin της Κίνας από πέρυσι, ωστόσο διαπιστώσαμε ότι τα δεδομένα έχουν τόσο μεγάλη διαφορά μεταξύ του ιστότοπού σας και ενός άλλου επίσημου (air.tjemc.org.cn) που αναφέρεται και στον δικό σας. Αναρωτιέμαι ποιο μπορεί να δώσει πιο ακριβή δεδομένα, καθώς θα επηρεάσει την απόφαση για εξωτερικούς ή εσωτερικούς χώρους. Παρακαλώ βοηθήστε με με αυτό το ζήτημα. Ευχαριστώ!</p> </blockquote> <p>Έχουμε γράψει αρκετά για αυτό το ζήτημα στο παρελθόν, για παράδειγμα από <a href='/faq/2013-01-19/shanghai-pm25-main-aqi-update-comparative-pm25-data-for-3-measurement-stations-in-shanghai/el/'><i>συγκριτικά δεδομένα PM <sub>2.5</sub> για τη Σαγκάη</i></a> , <a href='/faq/2013-06-25/singapore-psi-and-pm25-aqi-why-is-there-a-difference-between-the-two-readings/el/'><i>το PSI της Σιγκαπούρης και το PM <sub>2.5</sub> AQI</i></a> και πιο πρόσφατα για το <a href='/faq/2015-03-15/air-quality-nowcast-a-beginners-guide/el/'><i>nowcast</i></a> .</p> <p>Όμως, επειδή έχουμε ακόμα πολλές ερωτήσεις, γράφουμε τώρα αυτό το άρθρο για να εξηγήσουμε τη διαφορά των κλιμάκων AQI που χρησιμοποιούνται σε όλο τον κόσμο.</p> <p>Το πρώτο μέρος αυτού του άρθρου θα επικεντρωθεί στην Κίνα και το δεύτερο μέρος θα επεκτείνει τη σύγκριση σε κλίμακες που χρησιμοποιούνται στην Ιαπωνία, τη Νότια Κορέα, την Ινδία, την Ταϊλάνδη, τη Μαλαισία, την Ευρώπη, το Μεξικό κ.λπ.</p> <center style='color:#888'>.oOo.</center><br> <p>Επιστροφή στην αρχική ερώτηση σχετικά με τον δείκτη ποιότητας αέρα στο Tianjin της Κίνας, οι δύο παρακάτω εικόνες είναι στιγμιότυπα του ιστότοπου EPA της Tianjin air.tjemc.org.cn.
