Data type	Sources
Meteorological	World Meteorological Organization (WMO): Coordinates global climate monitoring and provides standardized datasets. NASA Earth Observatory: Offers satellite-based data on atmospheric and land-surface conditions. Copernicus Climate Change Service: Delivers long-term climate records and projections for climate adaptation strategies. NOAA (National Oceanic and Atmospheric Administration): Tracks weather patterns, oceanic changes and climate variability.
Air quality	WHO Global Health Observatory (GHO): Provides global data on air quality and its health impacts. EPA Air Quality Index (AQI): Tracks real-time pollution levels and provides public health advisories.
Vector-borne disease surveillance	Malaria Atlas Project: Provides GIS-based tracking of malaria distribution and risk factors. National Disease Surveillance Systems: Integrate climate, entomological and epidemiological data to improve outbreak prediction. Earth Observation Platforms (NASA, Copernicus): Offer remote sensing data to map environmental conditions favourable for vector proliferation. CDC Climate and Health Program: Tracks the impact of climate change on vector-borne diseases.*
Health surveillance systems	WHO Global Health Observatory (GHO): Aggregates international health data, including climate-related conditions such as heat stress and infectious disease outbreaks. CDC Heat and Health Tracker: Provides localized data on heat-related illnesses and health risks.* Integrated Disease Surveillance and Response (IDSR): Strengthens disease surveillance systems in resource-limited settings to track climate-health interactions.
Remote sensing and GIS	NASA Landsat Program: Provides satellite imagery for monitoring environmental changes over time. Copernicus: Offers Earth observation data for tracking climate and land-use changes. MODIS (Moderate Resolution Imaging Spectroradiometer): Tracks land surface temperature and vegetation cover changes. Sentinel Satellites (ESA): Provide high-resolution imagery for monitoring air pollution, water bodies and environmental hazards.
