Calibration of 2023/24 Otago ODIN data

This reports presents the method used to correct the measurements obtained by ODIN devices in Otago during 2023 and 2024. These corrections will enable direct comparisons of data from different ODIN sensors and between ODIN and regulatory, BAM-based data. The calibration will adjust the particulate matter (PM) data from individual ODIN sensors to account for systematic over or under sensitivity and achieve comparability with BAM data. This work is crucial for ensuring the accuracy and reliability of air quality data collected using ODIN sensors.
