Daily integrated estimates of shortwave solar irradiance reaching the Earth's surface, measured in watts per square meter (W/m²). The data is derived from the 0.6µm visible channel of the SEVIRI instrument on the Meteosat geostationary satellite, produced by EUMETSAT. Daily values are calculated by integrating all hourly values within a Universal Time (UT) day and are remapped onto a 0.05° regular grid.
Use Cases
- Model photovoltaic power output using daily integrated irradiance values (W/m²).
- Analyze spatial patterns of solar energy resources across the Meteosat coverage area using the 0.05° grid.
- Validate and calibrate numerical weather prediction models with satellite-derived surface irradiance data.
- Track seasonal and inter-annual variability in solar radiation for climate studies using the time-series of daily values.
Strengths
- Data derived from the operational SEVIRI instrument on the geostationary Meteosat satellite, providing consistent observation.
- Spatial data is remapped to a standardized 0.05° regular latitude-longitude grid.
- Daily values are integrated from hourly measurements, providing a complete diurnal cycle summary.
Limitations
- Specific temporal coverage, row count, and data volume are unknown.
- Spatial coverage is limited to the field of view of the Meteosat geostationary satellite, primarily covering Europe, Africa, and parts of the Atlantic.
- Accuracy may be affected by cloud detection algorithms and atmospheric correction models applied to the raw satellite signal.
