PVGIS — available products

The backend's product catalog (earthlens.pvgis.Catalog, loaded from the bundled pvgis_data_catalog.yaml) maps each product id to the PVGIS tool it drives, the REST endpoint, the default query params, and the canonical value columns. Select one with variables=["<id>"].

from earthlens.pvgis import Catalog

Catalog().available()        # -> ['seriescalc', 'tmy']
Catalog().get("seriescalc")  # -> Product(tool='seriescalc', endpoint='seriescalc', ...)

seriescalc — hourly radiation / PV power

Hourly solar-radiation time series over the requested year window. Columns:

column	description	units
time	timestamp (parsed to datetime64)	—
G(i)	global irradiance on the inclined plane	W/m²
H_sun	sun height	degree
T2m	2-m air temperature	°C
WS10m	10-m wind speed	m/s
Int	1 ⇒ radiation values reconstructed	—
P	PV system power (only when pvcalculation=1)	W

tmy — typical meteorological year

An hourly multi-year synthesis (8760 hours). Columns:

column	description	units
time	timestamp (normalised from PVGIS's time(UTC))	—
T2m	2-m air temperature	°C
RH	relative humidity	%
G(h)	global irradiance, horizontal plane	W/m²
Gb(n)	beam/direct irradiance, normal to sun	W/m²
Gd(h)	diffuse irradiance, horizontal	W/m²
IR(h)	surface infrared (thermal), horizontal	W/m²
WS10m	10-m wind speed	m/s
WD10m	10-m wind direction (0 = N, 90 = E)	degree
SP	surface (air) pressure	Pa

Every returned frame also carries the lat, lon, and product tag columns the backend adds per sampled point.

Not in the MVP

PVGIS exposes more tools (PVcalc grid-connected PV sizing, MRcalc monthly radiation, DRcalc daily radiation). The MVP ships the two tabular time-series tools above; the rest are catalog follow-ons.
