TIDE - Operational Ocean and Weather Intelligence

TIDE is a browser-based client and caching layer over operational forecast and observational products. It reads ECMWF IFS, Copernicus Marine Service, DWD ICON, and regional high-resolution models. On top of these it propagates HF-radar uncertainty analytically, ingests Lagrangian drifter data with IOC quality-control flags, and supports unstructured coastal meshes natively.

TIDE needs no installation. We either operate it for you as a managed service, or you host it on your own infrastructure and we support your sysadmin team. The architecture is DSGVO-compliant, and no data is transferred to third countries.

Research and operational oceanography - details

This edition is for scientists and operational forecasters at hydrographic institutes, research centres, and university coastal-modelling groups. It covers analytical HF-radar covariance uncertainty, SCHISM / FVCOM / FESOM unstructured meshes, and meteogram intercomparison across multiple models. It documents its conventions and known limitations explicitly.

Search & rescue - training and planning, advisory use only - details

This edition provides Leeway drift simulation (Allen 2005, 85 object types) for SAR training exercises, scenario planning, and preparedness at volunteer sea-rescue NGOs. Advisory use only. Operational SAR authority remains with the national rescue coordination centre.

TIDE is a client and integrator. Operational responsibility for the underlying forecasts and observations remains with the data providers. On request we integrate additional datasets into a deployment, such as regional NWP, proprietary model chains, or your own NetCDF / GRIB data.

Deployment	Managed service (we operate) or self-hosted on your infrastructure (we support your sysadmin team).
Configuration	Data sources, feature scope, and interface branding configured per deployment.
Access control	Session cookies (HttpOnly, Secure, SameSite=Strict), 24 h rotation. No third-party analytics.
Data protection	DSGVO-compliant architecture. User identifiers hashed (HMAC-SHA256, >= 32-char salt); retention policies enforced server-side.
AIS relay	HMAC-SHA512/256 authenticated UDP channel for NAT'd receiver sites.
Offline mode	Progressive Web App; core workflows available without connectivity.
Frontend	Browser-based, WebGL 2.0. Runs on Android devices down to 2 GB RAM.
Backend	Go binaries, SQLite, minimal dependencies. No Kubernetes, no third-country data transfer.

Pricing is specific to each deployment and quoted per customer. The quote depends on data sources, user count, feature set, branding, and hosting model. We handle academic, non-profit, and research-group arrangements case by case.

Terms of use and the Auftragsverarbeitungsvertrag (DPA) are available on request.
