[THIS IS A PRESS RELEASE]
The Philippine Space Agency (PhilSA) has done daily monitoring of satellite data since the Navotas landfill fire reportedly broke out on 10 April 2026. Coinciding with reports on Tuesday (28 April) that significant progress has been made in suppressing the fire, satellite data shows that nitrogen dioxide (NO2) concentration in Metro Manila has fallen below 6 April (pre-fire) levels for two consecutive days. Nitrogen dioxide is a pollutant produced from burning and is a component of smoke, and lower NO2 concentrations indicate a reduction in the volume of smoke emitted from the landfill fire.
