Good day! We are currently working on our undergraduate thesis which aims to perform spatio-temporal analysis of various air pollutants (NO2, SO2, CO, O3, Aerosol, Formaldehyde, and methane) concentrations in Metro Manila for years 2018 to 2021 by utilizing satellite data and ground-based measurements using integrated techniques of Geographic Information System (GIS) and/or Remote Sensing (RS).
In this regard, we would like to request available SO2 daily measurements from the existing and operational monitoring stations of Phivolcs in Metro Manila.
