Satellites play a vital role in keeping an eye on our planet and can help track health risks for different communities.
The European Union’s Copernicus program is mainly focused on observing Earth, especially regarding environmental data. A lesser-known aspect of this program is the Copernicus Health Hub, managed by the European Centre for Medium-Range Weather Forecasts (ECMWF). This hub specifically studies how environmental changes impact human health.
Satellites are not just for looking at the stars; they help forecast weather patterns, track pollution levels, and even assess allergy risks. Here are some ways space technology is improving public health:
Monitoring UV Rays
Too much exposure to UV rays can harm your skin and eyes, significantly raising the chances of skin cancer. To help manage this risk, the World Health Organization (WHO) created the UV index, which measures the sun’s strength and its potential dangers.
The Copernicus Atmosphere Monitoring Service (CAMS) tracks the UV index by studying factors like ozone levels and cloud cover. They can forecast UV radiation levels up to five days ahead. Many weather apps use this information, allowing users to check UV levels and get advice on sun protection.
Alerts for Air Quality
Air pollution is a serious health hazard, claiming around seven million lives each year. Poor air quality is linked to various issues, including lung cancer, heart disease, and respiratory problems. Satellites, paired with weather models, predict air quality levels. Apps such as BreezoMeter and Windy provide real-time updates about air pollution in different regions.
Monitoring Allergies
CAMS also tracks pollen levels, which can be particularly useful for allergy sufferers. By providing real-time info about pollen concentrations, it helps those with allergies manage their symptoms better. Research suggests that about 40% of Europeans are affected by pollen allergies, a number that could increase due to climate change. CAMS can forecast pollen levels of common types, like alder and birch, with a detailed accuracy of about 10 kilometers.
Diseases Spread by Mosquitoes
Mosquitoes are responsible for more deaths than any other animal, and they’re increasingly becoming a threat in Europe. Species like the Asian tiger mosquito and the yellow fever mosquito pose particular risks. Climate change impacts their migration, and the Copernicus Service gathers data on environmental changes that could create suitable habitats for these mosquitoes in Europe.
Their research includes predictions about the potential spread of illnesses like dengue and chikungunya, projecting into the future until the year 2085.
Understanding Heat Waves
Extreme heat poses serious risks, leading to heat-related illnesses and affecting heart and lung health. Records show that August 2023 and 2024 tied as the hottest, and heatwaves are expected to become more frequent and severe. Copernicus is collecting valuable data to help scientists understand and predict these patterns.
The Flemish Institute of Technological Research has used this data to create tools for urban planners. They can predict the intensity and impact of future heatwaves, helping cities prepare better for climate challenges in years to come.
