* The BWI Application Programming Interface (API) documentation is available here.
** Water level forecasts are available under one condition: there is an existing ground station on your chosen location (yours or open data), and the virtual station complements ground station data with water level forecasting capabilities.
***The water quality properties monitored are water color, water temperature, and turbidity, and the pollutants monitored are chlorophyll-A, algae, suspended matter, and cyanobacteria. This service is only available to clients who have deployed a water quality monitoring balloon.
**** BWI Terms & Conditions (T&Cs) are available here.
Each account is linked to its unique subscription plan, therefore, customers must select a plan that suits their requirements the most. Multiple subscription plans cannot be combined within one account. Consequently, one user cannot access several plans simultaneously. If your organization needs to subscribe to different plans, these plans will be available under separate contracts and accessible via separate accounts.
2 payment schemes are available: monthly direct debit (immediate payment and invoicing upon subscribing to the service), or yearly bank transfer (annual invoice issued by BWI on the 1st day of service to be paid by the client within 30 days as per BWI T&Cs).
Additional services may be available upon request and typically consist of bespoke training sessions. For system integration services or the deployment of physical sensors, BWI will typically introduce you to partners.
Basin digitization subscription plans are subject to change without notice. For existing clients, the price is not subject to change.
BWI specializes in providing near real-time estimates and forecasts of inland surface water bodies around the globe. It combines in-situ data, spaceborne observations, and machine learning to feed and empower hydrological and hydrodynamical models. Through an online, subscription-based service, BWI aims to make scalable – across space and time – hydrological software to address climate change-induced water stress.
