OGC CSW metadata discovery service for the catalogue of the Solar Atlas of Guinea. Lets another catalogue or a regional infrastructure query and harvest the records, their lineage, sources and licences.

OGC WFS vector data download service for the open layers of the Solar Atlas of Guinea. Provides access to the features and their attributes for analysis and download, notably in GeoJSON format.

OGC WMS map visualisation service for the open layers of the Solar Atlas of Guinea. Add it as a WMS service in QGIS, ArcGIS or any compatible client to display the layers without downloading them.

Calibration coverage status and expected residual uncertainty (p80) by sub-prefecture of Guinea, without the calibrated values, published in a dedicated layer. Shows where the calibration is robust and where local instrumentation is recommended.

Calibrated solar irradiance (GHI global horizontal and DNI direct normal) for the 340 sub-prefectures of Guinea, derived from the NASA POWER satellite corrected against ground measurements by a multi-donor ground calibration. The layer also carries the graded calibration confidence, the expected residual (p80), the latitude donor stations, and the derived operational quantities (HEP equivalent hours, specific yield, variability, diffuse fraction, humidex). For each sub-prefecture the layer also carries: the raw satellite-estimated global horizontal irradiation (NASA POWER, annual and monthly means, 1991 to 2020), for comparison with the calibrated value; the year-to-year variability of calibrated GHI (median year, value reached nine years out of ten, extreme years, 1991 to 2020); the monthly profile of calibrated DNI; and the coordinates of the reference point.
