GOME-2 (B+C) observations show absorbing aerosol index (AAI) plumes from wildfires over West Africa and west of Chile on 17 and 19 January, extending over the Atlantic and Pacific Oceans. Background: NASA/NOAA-21 VIIRS active fires (past 24 h) in red and GFS 800 hPa winds at 11:00 (from Ventusky).

Tuuli Perttula takes the stage at #WSW2026 Tailored Satellite-Based Air Quality Products for Operational Weather Forecasting: Turning complex satellite data into intuitive products that support real-time air quality monitoring and forecasting.

A transported SO2 plume from #HailyGubbi on 23-26 November, as seen by the GOME-2 instrument on the MetOp-B and MetOp-C satellites. 🌋 The volcano erupted on 23 November in Afar Region, Ethiopia.

Trees are nature’s carbon keepers - and satellites help us watch over them. 🌳 By tracking vegetation growth & forest health from space, scientists can see how much carbon dioxide plants are absorbing and where reforestation efforts are working. Find out more from our new case study: bit.ly/43n8wjk

EUMETSAT Climate Symposium. Here we are.

HCHO trend over Arabian Peninsula 2005-2023. Measured with GOME-2 instrument. EUMETSAT Climate Symposium starts tomorrow, see us there: www.eumetsat.int/eumetsat-cli... . #formaldehyde #HCHO #EUMETSAT #timeserie #climate

EUMETSAT Climate Symposium is on next week, 28-30 Oct. Meet us there. Here is Merged GOME-2 tropospheric NO2 column for Western Europe for the period 01/2007 - 12/2024. #GOME-2 #EUMETSAT #NO2 www.eumetsat.int/eumetsat-cli...

The ozone hole that exists every year, but is no longer growing. Proof that international environmental regulations and co-operation, like Montreal protocol, work ! Here we have temperatures in the polar vortex (left), and ozone concentrations (right). Time period 1 Aug - 6 Sep 2025

To extend the life of Metop-B, five satellite maneuvres are planned in September. The first maneuver is planned on Tue 2 Sep, with the following instrument outages (~ 2 orbs): IASI 07:12:41-13:06:45 GOME-2 10:25:24-13:49:13. The nexts are planned for 9, 16, 23 and 30 Sep. Image: ESA/AOES Medialab
