Open Climate Service — seNorge plugin

An installable Open Climate Service (OCS) plugin that provides seNorge 2018 daily climate data for Norway: mean temperature (tg) and precipitation (rr), 1 km × 1 km on the UTM33 grid (EPSG:32633), daily from 1957.

Data is downloaded from the Norwegian Meteorological Institute's THREDDS OPeNDAP service.

It is the reference implementation for OCS's installable-plugin mechanism (dhis2/open-climate-service#118).

Datasets

id	kind	notes
senorge_temperature_daily	source (tg, degC)	downloaded by SeNorgePlugin
senorge_precipitation_daily	source (rr, mm/d)	downloaded by SeNorgePlugin
senorge_temperature_daily_normal_1991_2020	derived (static)	day-of-year normal via the climate_normal workflow
senorge_temperature_daily_anomaly_1991_2020	derived (static)	daily anomaly via the climate_anomaly workflow

Install

In an OCS instance, add the plugin and OCS auto-discovers it — no plugins_dir wiring:

uv add osc-senorge-plugin

Its datasets then appear in /datasets and can be ingested like any built-in dataset:

curl -X POST http://127.0.0.1:8000/ingestions \
  -H 'Content-Type: application/json' \
  -d '{"dataset_id": "senorge_temperature_daily", "temporal_extent": ["2024-01-01", "2024-01-31"]}'

The derived normal/anomaly datasets are static templates: their data is written by the OCS built-in climate_normal / climate_anomaly workflows run against the source datasets. They ship here so the whole seNorge family installs as one plugin.

How it works

The package declares an open_climate_service.plugins entry point pointing at its top-level package. OCS discovers all installed packages in that group and loads their datasets/*.yaml templates (and, if present, their processes/ and workflows/); the ingestion plugin class (osc_senorge_plugin.datasets.senorge.SeNorgePlugin) is imported by its dotted path at ingest time. plugins_dir continues to work and takes precedence on id conflicts.
