hydro & meteo GmbH

hydro & meteo GmbH is a German hydrometeorological consultancy and software developer headquartered in the old town of Lübeck. Founded in 1999 by Dr. Thomas Einfalt, the company describes itself as a specialist partner for hydrometeorology with more than 25 years of experience. Its core work revolves around precipitation and radar data: it produces quality-controlled, corrected radar datasets and uses them together with COSMO forecasts to compute predictions and to develop warning systems for heavy rainfall and flooding. Early warnings, the company argues, can help reduce damage from extreme weather events. The firm applies its datasets to a wide range of tasks, including extreme-value statistics and comparative assessment against KOSTRA detailed analyses, as well as studies and expert reports on heavy-rain events and urban flash floods. Its portfolio spans the conception, execution, and leadership of projects for clients at home and abroad. Clients and partners include water-management associations, cities and municipalities, and research funders such as the EU and German ministries including BMBF, BMDV, and BMWK. The company states that it works with customers and partners in Germany, Europe, and worldwide, with listed contacts in Germany, Europe, and Asia and Australia. hydro & meteo is a small, expert-driven team. Its staff includes meteorologists, hydrologists, software developers, data engineers, and data scientists. Dr. Thomas Einfalt serves as Senior Consultant and founder; Markus Jessen, Alrun Jasper-Tönnies, and Marianne Wunnenberg are listed as managing directors (Geschäftsführer). The team also includes meteorologist and software developer Claudia Fennig, meteorologist Alexander Strehz, meteorologist and software engineer Dr. Dan Willuweit, hydrologist and data engineer Sebastian Luers, meteorologist Dr. Annika Jahnke-Bornemann, meteorologist and oceanographer Jaya Kelvin, meteorologist Friederike Bégué, data scientist and mathematician Jule Schlimme, and hydrologist Anne Kappler. The company emphasizes social and climate responsibility. Since its founding in 1999 it has offered flexible working hours compatible with family needs and the option of home office, plus company health insurance for all team members. Business travel is primarily by train, with flights considered only for international trips where they save substantial time. For climate and inner-city parking reasons the firm owns no company car and has used the Stattauto Lübeck car-sharing service since founding. It is a Job-Rad partner, allowing employees to lease bicycles. Recent activities include a NIQKI project-partner meeting hosted in Lübeck's Haus der Kaufmannschaft, approval of a three-year research allowance for R&D on novel software linking rain-gauge, radar, and satellite data in five-minute intervals with automated checking of reference values, and participation with three contributions at the UIS 2026 workshop in Tönning, where Alexander Strehz presented the new SCOUT precipitation portal.

hydro & meteo GmbH was founded in 1999 by Dr. Thomas Einfalt and has been based in the heart of Lübeck's old town for more than 25 years. From its founding, the company has positioned itself as a specialist partner for hydrometeorology, focusing on precipitation and radar data and their application to forecasting, warning, and water-management problems. Over the decades the firm built expertise in producing quality-controlled, corrected radar datasets and combining them with numerical weather prediction such as COSMO forecasts. This data foundation supports warning systems for heavy rainfall and flooding, extreme-value statistics, comparative evaluation against KOSTRA detailed analyses, and studies and expert reports on heavy-rain events and urban flash floods. The company has conceived, executed, and led projects for a range of clients at home and abroad, including water-management associations, cities and municipalities, and research programs funded by the EU and German ministries such as BMBF, BMDV, and BMWK. hydro & meteo has also maintained a distinctive workplace culture since 1999, combining flexible, family-friendly working hours and home office with climate-conscious practices: train-first travel, no company car (using Stattauto Lübeck car-sharing since founding), and a Job-Rad bicycle leasing partnership. The team is composed of meteorologists, hydrologists, software developers, data engineers, and data scientists, with Dr. Thomas Einfalt as founder and Senior Consultant and Markus Jessen, Alrun Jasper-Tönnies, and Marianne Wunnenberg as managing directors. Recent milestones include hosting a NIQKI project partner meeting in Lübeck, receiving approval for a three-year research allowance for R&D on software that links rain-gauge, radar, and satellite data in five-minute intervals with automated checking of reference values, and contributing three presentations at the UIS 2026 workshop in Tönning, where Alexander Strehz presented the new SCOUT precipitation portal.
