📍Two inspiring days at the #AfricaCleanAirForum2026! CitiObs Project Coordinator Nuria Castell hosted a session on Strengthening Citizen Science in Africa, highlighting the value of citizen engagement and low-cost air quality monitoring for better environmental data and decision-making.

📍 #CitiObs is at the Clean Air Forum in Pretoria today! Our coordinator, Nuria Castell is sharing expertise on low-cost sensor management — calibration, data handling & open data to help close air quality data gaps in African cities. 🌍 #CleanAirForum #AirQuality #CitizenScience

🌍 CitSci Africa #Conference, July 2nd: workshop on air quality monitoring, presenting the #CitiObs Knowledge Platform & Environmental Monitoring #Toolkit to participants across #Africa. Led by Nuria Castell (NILU), with an exercise on adapting the toolkit to African Citizen Observatories. 🌱

Big news: 📡 WebSub Asynchronous Messaging Standard is now officially published and #CitiObs is proud to have contributed to making it a reality. So what does this actually mean? The CitiObs implementation is already live 👉 websub.citiobs.secd.eu Full standard 👉 docs.ogc.org/is/24-032r1/...

📢 A powerful Citizen Science Dialogue on Air Quality and Health! As part of the CitiObs initiative, this dialogue brought together researchers, citizen scientists, and CitiObs Fellows to explore air quality and its direct impact on our well-being. 🎥 Link in the first comment 👇👇👇

Some great resources from our friends at the ECS project: 🎙️ The ECS Podcast Hub is live! 👉 citizenscience.eu/ecsa/ecs-pod... 📅 Online event: "No project is an island: Bridges towards a joint legacy for the future of citizen science in Europe" (June 17th!) 👉 citizenscience.eu/ecs_project/...

How can citizen-generated air quality data support better health outcomes? We hosted the first #CitiObs Citizen Science Dialogue — 50+ participants, big conversations on air, health & action. Key message: citizen science is not only about data. It's about trust, awareness & change. 👉citiobs.eu

A few weeks since #EGU26 in Vienna and we're still energised! 🌍 Co-convening a session on climate-resilient cities reminded us how citizen-generated data bridges communities, researchers & policymakers. Exciting things ahead! 🌱 #CitiObs

At the ACTRIS Science Conference 2026 (Oslo, 20–23 April), the CitiObs team contributed to discussions on air quality and atmospheric research. CitiObs contribution: integrating quality-controlled low-cost sensor data into machine learning for improved air quality mapping 👇 Check out the poster

📢 Glad to have welcomed the CitiObs Fellows from around the world! 🌍 Citizen observatories from across 5 continents, all working towards more inclusive, data-driven, and community-led environmental action. 🎥 Watch the video via the link in the first comment 👇👇👇 🔗 Learn more: www.citiobs.eu

#Air pollution can change dramatically from one street to the next but most monitoring systems can’t capture that level of detail. So how do we actually map what people are really breathing? Read the full blog to see how it works (below in the comments 👇👇👇)

Citizen science in action 🌍 On March 10th in Cluj-Napoca, kids and teens explored how to build air quality sensors using Arduino 🤖 They learned that they can collect real data and help their community. Curiosity → action → impact 🌱 #CitizenScience #AirQuality #STEM #OpenData

🌍 Inspiring days in #Oslo for the final #CitiObs Face-to-Face Plenary (24–26 March)! As we enter the last 9 months, we aligned on where we stand, what we aim to achieve, and how to get there. Back home energised and ready to maximise our efforts for a strong project closing 💪

📢 This Thursday (March 19) at #RDA VP26 Nuria Castell will speak on: FAIRification of Citizen-Generated Data 🕗 8:00 CET How can we make citizen-generated data FAIR and better connect it to research? Learn more 👇 www.rd-alliance.org/plenaries/p26/ #CitizenScience #FAIRdata #OpenScience
