Since early 2016, anemos-jacob GmbH appears under the trademark aj. In February 2016, Prof. Dr. Jacob quit as managing director in order to be able to concentrate on her new positions as director of GERICS (Climate Service Center Germany) and as professor at the Leuphana University of Lüneburg.


The limited company anemos-jacob GmbH was formed in 2003. Dr. Daniela Jacob and Herbert Schwartz became its managing directors.


Due to its excellent reputation, anemos-jacob faced a strongly growing demand from the year 2000 onwards. This initiated a substantial growth of the company.


In 1995, she founded the succeeding company anemos-jacob.


Dr. Daniela Jacob created the independent company anemos together with two other meteorologists in 1990. There, she completed more than 200 wind resource assessments for sites in all parts of Germany.
