[2024-Jan-30] Upcoming Announcement of Opportunity for Sentinel-4 and Sentinel-5 Cal/Val: In spring 2024 ESA and EUMETSAT will release jointly an Announcement of Opportunity (AO) Call inviting the science and user community of the Copernicus satellite missions Sentinel-4 (S4) and Sentinel-5 (S5) to propose Cal/Val activities for the operational mission products. The primary objectives of the activities triggered by the AO Call are to assess and establish the initial post-launch data quality of the mission products, support the consolidation of the processors, and verify that the mission products meet the applicable data quality requirements. The AO covers the early post-launch mission phase until the public release of the products. The AO Call will be released about one year before the expected launch date of the first satellites (anticipated in 2025): either MTG-S1 with the S4/UVN PFM on board, or MetOp-SG A1 with the S5/UVNS PFM on board. A proposal period of 2 months (starting from the date of the AO Call release) is foreseen.
[2024-Jan-17] Save the date: In the week of 3 - 6 June 2024 a hybrid OMI-TROPOMI Workshop will be held in Boulder, Colorado at the NCAR Foothills Laboratory and online. Contributions will be welcome for the following possible themes:
- Long-term Records
- AQ and Emissions
- Applications and Societal impacts
- GEO and Polar Orbit AQ constellations (including OMI, TROPOMI, GOME-2, OMPS, GEMS, TEMPO, etc.)
- Algorithm Improvements
- New Mission Ideas

After three years of virtual events, the CEOS Atmospheric Composition Virtual Constellation (AC-VC) and the Atmospheric Composition Sub Group of the CEOS Working Group on Calibration and Validation (WGCV ACSG) organize the CEOS AC-VC/ACSG Atmospheric Composition Joint Meeting 2023 in Brussels on October 24-27, 2023. This event will be the opportunity to exchange latest updates on atmospheric composition missions and coordinate international activities pertaining to satellite measurements of Air Quality & Aerosols, Greenhouse Gases and Ozone, and topics like Cal/Val requirements for the CEOS constellations and Science serving society.
ESA organizes on October 10-11, 2023, the Earth Explorer 11 User Consultation Meeting in Bucharest, Romania. This user consultation is planned to support the selection of up to two missions for the ESA Earth Explorer 11 satellite. Three of the four candidate missions having passed the first selections address atmospheric composition and parameters: CAIRT, a tomographic imaging IR limb sounder targeting global profiling of ozone, temperature, water vapour, and key halogen and nitrogen compounds in the 5 to 115 km altitude range; NITROSAT, combining TIR and VIS spectrometers to monitor tropospheric ammonia (NH3) and nitrogen dioxide (NO2) at 1-km on-ground resolution; and WIVERN, the WInd VElocity Radar Nephoscope for observing global winds, clouds and precipitation.
NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument lifted off on its way to geostationary orbit at 12:30 a.m. (EDT) on Friday, April 7, 2023. TEMPO will be the first space-based instrument to measure air quality over North America hourly during the daytime and at spatial resolution of several square kilometers. TEMPO commissioning activities started in late May.
Request for Information for NASA’s Terra, Aqua, and Aura Data Continuity Workshop - NASA announces the release of a Science Mission Directorate (SMD) Request for Information (RFI) via NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES) that seeks input from the science community that will be considered in the development and implementation of a Terra, Aqua, and Aura (T/A/A) data continuity workshop planned for Spring 2023. NASA requests input from the science community (comprising research, applied research, and applications) addressing data product continuity issues resulting from the eventual loss of the Terra, Aqua, and Aura satellites (more). Release Date: March 1, 2023. Response Date: April 4, 2023.
