Satellites are becoming a powerful tool in protecting public health. They track air pollution, disease risks, and climate patterns, giving us the data we need to stay safe. The European Union’s Copernicus programme plays a key role in monitoring Earth and its impact on human health. This initiative helps scientists understand how environmental changes affect our well-being.
Satellites help in many ways. They forecast extreme weather, track disease outbreaks, and more. Below are five key ways satellites are helping protect public health.
1. UV Radiation Warnings for Skin Health
Excessive exposure to ultraviolet (UV) radiation is harmful. It increases the risk of skin cancer, sunburn, and eye issues like cataracts. To reduce these risks, the World Health Organization (WHO) developed the UV Index. It’s a global standard to measure sun intensity.
The Copernicus Atmosphere Monitoring Service (CAMS) helps track UV radiation. It uses data on ozone levels, cloud cover, and atmospheric particles. CAMS provides UV forecasts for up to five days. This helps people check UV levels and take protective actions like applying sunscreen, wearing protective clothing, or staying indoors.
2. Real-Time Monitoring of Air Pollution
Air pollution is a major health risk. It contributes to seven million premature deaths each year. In Europe, poor air quality is responsible for around 500,000 early deaths annually. It leads to diseases like asthma, heart problems, and strokes.
Satellites help monitor pollution levels. Combined with meteorological models, satellites can forecast air quality trends. Apps like BreezoMeter and Windy use this data to provide real-time updates. They help people avoid harmful pollutants. This is especially helpful for those with respiratory issues.
3. Helping Allergy Sufferers with Pollen Forecasts
Allergy season is becoming longer and worse due to climate change. Pollen allergies affect nearly 40% of Europeans. Satellites help track pollen levels from plants like birch, alder, olive, and grass.
CAMS tracks pollen levels using satellite data and models. The forecasts help people prepare for allergy season. With a four-day notice, individuals can take medication, change their outdoor plans, or take extra precautions. Satellites also show how pollution and pollen mix. Poor air quality can worsen allergic reactions.
4. Preventing Disease Outbreaks by Tracking Mosquitoes
Mosquitoes are the world’s deadliest animals. They spread diseases like malaria, dengue, and chikungunya. Changing weather patterns allow mosquitoes to spread into new regions. This includes parts of Europe.
Satellites track factors like humidity, temperature, and stagnant water. These factors influence mosquito breeding. The Copernicus Service uses this data to predict where mosquito-borne diseases will spread. This helps health officials prepare and take action. For example, the Asian tiger mosquito, a carrier of dengue, is spreading across Europe. Projections show this will continue until at least 2085.
5. Predicting Heatwaves to Save Lives
Heatwaves are becoming more common and severe due to climate change. They cause heatstroke, dehydration, and heart problems. According to Copernicus data, August 2023 and 2024 were the hottest on record. These extreme heat events are expected to increase.
Satellites track heat patterns and predict future temperature spikes. This data helps urban planners make cities more heat-resilient. The Flemish Institute of Technological Research uses Copernicus data to predict heat-related deaths under different climate scenarios. Their work helps policymakers prepare for heatwaves in the future.
Satellites are changing how we protect public health. They provide real-time data on UV levels, air pollution, pollen, mosquitoes, and heatwaves. This data helps scientists, governments, and individuals take action to stay safe.
As climate change brings more challenges, satellites will be crucial in protecting our health. They help us predict problems and take preventive measures. With the right data, we can make smarter decisions to protect ourselves and others. Satellites are an essential part of building a safer, healthier future.
