ជាមួយនឹង COVID-19 រីករាលដាលពាសពេញពិភពលោក ក្រុមការងារគម្រោងសន្ទស្សន៍គុណភាពខ្យល់ពិភពលោកបានឃើញការកើនឡើងនៃសំណើសម្រាប់ទិន្នន័យសកលដែលគ្របដណ្តប់លើផែនទីពិភពលោកទាំងមូល។ ជាលទ្ធផល គម្រោង WAQI ឥឡូវនេះកំពុងផ្តល់នូវសំណុំទិន្នន័យដែលខិតខំប្រឹងប្រែងថ្មី ធ្វើបច្ចុប្បន្នភាព 3 ដងក្នុងមួយថ្ងៃ និងគ្របដណ្តប់ទីក្រុងធំៗប្រហែល 380 នៅលើពិភពលោក ចាប់ពីខែមករា 2015 រហូតមកដល់បច្ចុប្បន្ន។
ទិន្នន័យសម្រាប់ទីក្រុងធំៗនីមួយៗគឺផ្អែកលើមធ្យម (មធ្យម) នៃស្ថានីយ៍ជាច្រើន។ សំណុំទិន្នន័យផ្តល់នូវគម្លាតអប្បបរមា អតិបរមា មធ្យម និងគម្លាតស្តង់ដារសម្រាប់ប្រភេទសត្វបំពុលបរិយាកាសនីមួយៗ (PM 2.5 , PM 10 , Ozone ...) ក៏ដូចជាទិន្នន័យឧតុនិយម (ខ្យល់ សីតុណ្ហភាព ...)។
ប្រភេទសត្វបំពុលខ្យល់ទាំងអស់ត្រូវបានបំប្លែងទៅជាស្តង់ដារ EPA របស់សហរដ្ឋអាមេរិក (ឧ. គ្មានការប្រមូលផ្តុំឆៅ)។ កាលបរិច្ឆេទទាំងអស់គឺផ្អែកលើ UTC ។
ជួរឈររាប់គឺជាចំនួនគំរូដែលប្រើសម្រាប់គណនាគម្លាតមធ្យម និងស្តង់ដារ។
តម្លៃមធ្យមទីក្រុងត្រូវបានគណនាក្នុងមួយថ្ងៃដោយប្រើតម្លៃ AQI ទាំងអស់សម្រាប់ស្ថានីយ៍ដែលមាន
សំណុំទិន្នន័យសម្រាប់ឆ្នាំ 2015 ~ ឥឡូវនេះ៖
ប្រសិនបើអ្នកទទួលបានលទ្ធផលណាមួយពីការស្រាវជ្រាវរបស់អ្នកដោយប្រើសំណុំទិន្នន័យនេះ សូមប្រាប់យើងឱ្យដឹងដោយផ្ញើសារមកយើងតាមរយៈ ទម្រង់សំណើរ វេទិកាទិន្នន័យ ជាមួយនឹងតំណភ្ជាប់ទៅកាន់លទ្ធផលស្រាវជ្រាវ ឬអត្ថបទរបស់អ្នក។ យើងនឹងចងក្រងបញ្ជីនៃការស្រាវជ្រាវដោយផ្អែកលើគុណភាពខ្យល់ COVID-19 ទាំងអស់ ហើយបង្កើតទំព័រថ្មីមួយដើម្បីឱ្យអ្នករាល់គ្នាបានឃើញ។
