Met Office NIMROD

UK-wide composites ingested continuously, cached, and exposed as ready-to-download GeoTIFFs.

On-demand accumulations

Request bespoke hourly or daily spans, or grab cached rolls instantly with signed download links.

Operational guardrails

Live ingestion monitors, health endpoints, and historical issue tracking keep pipelines honest.

Accumulation

Bespoke windows without scripting

Pick any hourly or daily span inside retained coverage and RainMap stitches the data into a single GeoTIFF, returning exactly the period you need with no intermediate storage.

Cache tier

Instant roll-ups for dashboards

Daily and hourly composites are cached and signed up-front so you can wire dashboards or alerts without waiting for compute-heavy aggregation jobs to finish.

Reliability

Transparent operations

Status APIs, issue tracking, and retention telemetry surface ingestion hiccups before they affect downstream modelling work. Everything is auditable.

Workflow

From ingestion to download in four moves

  1. 01 Ingest Met Office NIMROD composites into resilient object storage every five minutes.
  2. 02 Pre-compute hourly + daily accumulation layers and publish signed URLs to the cache tier.
  3. 03 Expose bespoke accumulation builder controls for ad-hoc periods via the Accumulation page / API.
  4. 04 Feedback live into the Status and Data Issues dashboards so nothing silently drifts.

Need the source GeoTIFFs?

Archive downloads zip exactly the hourly or daily tiles you specify—ideal for ETL jobs.
