Abstract EN
Accurate and reliable daily global weather reports are necessary for weather forecasting and climate analysis.
However, the availability of these reports continues to decline due to the lack of economic support and policies in maintaining ground weather measurement systems from where these reports are obtained.
Thus, to mitigate data scarcity, it is required to utilize weather information from existing sensors and built-in smartphone sensors.
However, as smartphone usage often varies according to human activity, it is difficult to obtain accurate measurement data.
In this paper, we present a heuristic-based pairwise gossip algorithm that will calibrate smartphone-based pressure sensors with respect to fixed weather stations as our referential ground truth.
Based on actual measurements, we have verified that smartphone-based readings are unstable when observed during movement.
Using our calibration algorithm on actual smartphone-based pressure readings, the updated values were significantly closer to the ground truth values.
