This September the training team at EUMETSAT is going to kick off a series of online short courses that will cover weather, oceanography, air quality and climate.

The short courses are open to all interested participants and address a wide range of attendees, from service providers to young (and less young) scientists and forecasters.

More information about the online series and the course schedule is available on Moodle ^EXT, the EUMETSAT training platform at https://training.eumetsat.int/course/index.php?categoryid=97 ^EXT. Here participants can find information about the content and format of the sessions, and they can already register their interest ^EXT in the courses.

Each short course will offer a webinar with a presentation, a demonstration of data discovery and data application. Some courses will also include a follow-up self-paced phase where participants will have the opportunity to further explore the data and discuss it with experts.

YESS (the Young Earth System Scientists community) focuses on researchers working in the interdisciplinary field of Earth system sciences, including social and natural scientists.
Members within YESS cover a large breath of scientific expertise, including – but not limited to – weather, climate, geophysics, economy, engineering, hydrology, architecture, anthropology, governance, many more.

YESS members are organizing the webinar series on “Career Opportunities and Experiences in Climate and Weather Research for Latin America scientists”.

The first meeting will be on August 26th at 15UTC and 2 ECRs will give their testimonies.
