Solar & Wind Atlas — available layers#
The solar-wind-atlas backend ships 16 curated layers across the two atlases.
Pick one or more with variables=. Every layer is a static global climatology
grid in EPSG:4326.
Global Solar Atlas (download_zip transport)#
Distributed as DEFLATE GeoTIFF ZIP archives (downloaded once, cropped locally). Values are long-term-average daily totals.
variables= id |
Layer | Units |
|---|---|---|
ghi |
Global horizontal irradiation | kWh/m²/day |
dni |
Direct normal irradiation | kWh/m²/day |
dif |
Diffuse horizontal irradiation | kWh/m²/day |
gti |
Global irradiation, optimally tilted surface | kWh/m²/day |
pvout |
Photovoltaic power potential (specific PV output) | kWh/kWp/day |
opta |
Optimum tilt of PV modules | degree |
Global Wind Atlas v3 (vsicurl transport)#

Per-height mean wind speed at 10/50/150/200 m is not published as a public windowable COG (only the 100 m speed is), so it is out of scope for now; the Weibull parameters above let you reconstruct the speed distribution at each height.
Facade aliases#
Four friendly aliases route to the same backend:
data_source="global-solar-atlas"/data_source="gsa"data_source="global-wind-atlas"/data_source="gwa"
data_source="solar-wind-atlas" works with any layer id (solar or wind).
