The following files include raw, unvalidated PM2.5 data for the MetOne 1020 Beta Attenuation Monitor (BAM) operating at the Bayankhongor reference station. Monitoring started on November 6, 2019.
These files are updated every hour.

The above files contain identical information.
The data fields are:
- Date/Time [yyyy/mm/dd hh:mm] where the time stamp is the end of the sampling hour; our convention for data reporting is to convert all time stamps to start-of-hour.
- Conc = PM2.5 concentration, in milligrams per cubic meter
- Qtot = total air volume sampled in the hour, in cubic meters
Note, these files are not used to validate the data. A different data stream has more-detailed diagnostic information.
