First images From Copernicus Sentinel-5A

First images From Copernicus Sentinel-5A

Handout photo dated October 13, 2025 shows Copernicus Sentinel-5A has delivered its first images after its launch on 13 August 2025, marking a significant milestone in the monitoring of air quality from space. The Sentinel-5 mission provides observations of key air pollutants, essential climate variables, and stratospheric ozone, which is the protective layer shielding life on Earth from harmful ultraviolet radiation. This visualisation, created with Sentinel-5A data acquired on 13 October 2025, shows atmospheric concentrations of two trace gases: ozone (O₃) and formaldehyde (HCHO). The image on the left presents the formaldehyde vertical column density. Elevated concentrations along the northwestern coast of Angola are linked to emissions from wildfires, while increased levels over the Central African Republic stem from a combination of fire activity and biogenic emissions. The image on the right shows a global map of ozone. The hole in stratospheric ozone above Antarctica is clearly visible, with column den

Water supply halted in 4 cities in Chiba

Water supply halted in 4 cities in Chiba

TOKYO, Japan - Photo taken May 19, 2012, from a Kyodo News helicopter shows the Karasu River in Takasaki, Gunma Prefecture. Hazardous formaldehyde has been detected at some water plants in Gunma, Saitama and Chiba prefectures, leading to the water supply being cut off in four cities in Chiba the same day. Officials of Saitama Prefecture said that the upstream area of the Karasu River could be a potential source of the contamination, noting that there are local businesses dealing with substances that generate formaldehyde.

KANAZAWA, Japan - Eiichi Tamiya, professor of the Japan Advanced Institute of Science and Technology (JAIST), shows off a portable sensor designed to quickly detect formaldehyde, a chemical that causes so-called sick-house syndrome, which he and one of his students have jointly developed. Tamiya said the 10-by-20 centimeter sensor can accurately measure the concentration of formaldehyde within three minutes.
