Climate Service

Overview

The Climate Service provides APIs for climate anomaly data sourced from Open-Meteo and ERA5 reanalysis. Track temperature and precipitation deviations from historical norms across global climate zones. Base Path: /api/climate/v1

ListClimateAnomalies

Retrieves temperature and precipitation anomalies from ERA5 data. Endpoint: GET /api/climate/v1/list-climate-anomalies

min_severity

enum

Optional filter by anomaly severity.Values: NORMAL, MODERATE, EXTREME

Response

Anomaly Severity Levels

Normal

Within expected variation from historical norms.

Moderate

Notable deviation requiring monitoring.

Extreme

Severe deviation requiring immediate attention.

Anomaly Types

WARM

Above-normal temperatures

COLD

Below-normal temperatures

WET

Above-normal precipitation

DRY

Below-normal precipitation

MIXED

Combination of temperature and precipitation anomalies

Data Source

Climate anomaly data is sourced from:

Open-Meteo: High-resolution climate data API
ERA5 Reanalysis: ECMWF’s fifth generation reanalysis dataset
Updates hourly with new observations
Historical baseline computed from 1991-2020 normals
