China’s NO2 emissions now rising

In English Sentinel-5p

Olivier Hagolle, 28 mars 2020

NO2 emissions are rising again over China, showing the slow recovery of Chinese industry after a two-month shutdown. The graph below was obtained from Sentinel-5p data using the NO2 time series Google Earth Engine app.

Total vertical column of NO2 (ratio of the slant column density of NO2 and the total air mass factor) from 01 January to 27 March. Daily average over Mainland China. Data source: Copernicus Sentinel-5P NRTI NO2: Near Real-Time Nitrogen Dioxide.

BIOMASS, the third launched satellite mission designed at CESBIO !

After SMOS in 2009, and VENµS in 2017, the CESBIO Laboratory is very proud to see its third proposed mission, Biomass, reach orbit. As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]

Copernicus should keep S2A operational after S2C launch

The launch of Sentinel-2C (S2C) is scheduled on the 4th of September 2024, next week ! After 3 months of commissioning phase, S2C will replace S2A, to fulfill the Sentinel-2 mission together with S2B. S2B will later be replaced by S2D. The current plans are to keep S2A as a redundant satellite, in case something […]
