Get the 45-year historical record off the rate-limited public Open-Meteo archive API by running a private Open-Meteo instance that serves the era5_seamless blend (0.1° ERA5-Land + 0.25° ERA5 for gusts) from the compressed .om archive in object storage, mounted on the host with rclone. - climate.py: make ARCHIVE_URL env-driven (THERMOGRAPH_ARCHIVE_URL) and pin models=era5_seamless on the archive fetches only, so a self-hosted instance serves the same 0.1° resolution; forecast path unchanged. The public API's default is already seamless, so dev/beta (URL unset) behave identically. - docker-compose.openmeteo.yml: open-meteo-api + two rolling sync workers (era5_land 0.1°, era5 0.25° for gusts), bind-mounting the object-storage mount; the overlay points the app at the local instance. - Makefile: om-up / om-down / om-backfill (one-time full-history backfill). - Terraform: per-host openmeteo flag layers the overlay, renders OM_DATA_DIR, and provisions the host rclone systemd mount from the bucket credentials. - deploy/openmeteo: operator runbook + rclone mount unit template.

#
|
|
# Before installing:
|
|
# - Replace BUCKET_NAME below with the object-storage bucket name.
|
|
# - `--allow-other` requires `user_allow_other` to be set in /etc/fuse.conf.
|
|
# - The `om-archive` remote must exist in /etc/rclone/rclone.conf (S3 remote).
|
|
#
|
|
# Install:
|
|
# sudo install -m0644 rclone-mount.service.example /etc/systemd/system/rclone-om.service
|
|
# sudo systemctl daemon-reload
|
|
# sudo systemctl enable --now rclone-om
