​climate

Latitude in degrees (North is positive).

Longitude in degrees (East is positive).

Altitude in meters above mean sea level or "auto".

Azimuth angle of the surface.
• 0° = oriented towards the north
• 90° = oriented towards the east
• 180° = oriented towards the south
• 270° = oriented towards the west

Tilt angle of the surface.
• 0° = horizontal
• 90° = vertical

Local terrain situation.

Horizon of the requested location.
• flat: Flat horizon (all horizon elevations are 0°).
• auto: Horizon is determined automatically using a high-resolution digital elevation model with a spatial resolution of approx. 30m.
• [comma-separated values]

[comma-separated values]: provide 360 integer values representing elevation angles (in degrees) of the horizon in 360 directions. Elevation angles must be ≥0° and <90°. Index corresponds to azimuth:
Index 0 = 0° (North)
Index 90 = 90° (East)
Index 180 = 180° (South)
Index 270 = 270° (West)
Each value indicates the elevation angle at the corresponding azimuth.

Fixed albedo to use. If not set, a default albedo of 0.2 is assumed and albedo changes due to snow fall are modelled.

Monthly mean atmospheric Linke turbidity.

• auto: turbidity is taken from the Meteonorm database.
• [comma-separated values]: 12 floating point values representing monthly atmospheric turbidity.

Temporal resolution of the resulting time series.

Response data format.

Radiation model to be used for minute computation. This option has only an effect when computing minute time series.

Algorithm to be used to compute diffuse irradiance from global irradiance.

Algorithm to be used to compute tilted irradiance.

Random seed to be used for stochastic processes. Two identical requests with the same random seed will yield identical results.

Algorithm to be used to compute clear sky irradiance

Probability-of-exceedance (PoE) reference used to generate TMY GHI and temperature.

• none: Uses median PoE50 values
• (coming soon) poe_10_year: Uses annual PoE10 (90th percentile) values
• (coming soon) poe_90_year: Uses annual PoE90 (10th percentile) values
• (coming soon) poe_10_months: Uses monthly PoE10 values
• (coming soon) poe_90_months: Uses monthly PoE90 values
• (coming soon) worst_case_year: Uses a combination of PoE10 in summer and PoE90 in winter

Version of Meteonorm climatological data to be used. Allows to compute TMYs based on the data of older Meteonorm versions.

Future climate scenario.

Central year for a 20-year reference period in the future.
