Goal: CliC grants aim at increasing the engagement of Early Career Scientists in CliC. The project strives for gender balance and geographical diversity so submissions from regions currently under represented in CliC, such as Asia and Africa, are particularly encouraged.

Objectives: Applications shall target CliC´s vision and mission as described in the Strategic Plan 2022-2031, as well as to address one or more of its five strategic areas, as follows: 

1. Engagement of a broad and diverse community in cryosphere research
2. Cryosphere ice loss- assessment and impacts
3. Projection of future ice loss and impacts
4. System description of the cryosphere regions
5. Knowledge syntheses and communication to stakeholders

Timeline: Activities must be completed within one year after the project´s acceptance unless otherwise outlined in the proposal.

Who can apply:

• Early Career Scientist: students enrolled in a PhD programme and scientists who have obtained a PhD within 7 years by 1 March 2023. The period excludes career breaks due to parental leave, health issues, etc.
• For research visits: the visiting institution must differ from the applicant´s country of origin and current country of residence.

Submission deadline: 1 March 2023 at 23:59 /11:59 pm UTC

Ewa Bednarz,
Martina Bramberger,
Mohamadou Diallo,
Rolando Garcia,
Marco Giorgetta,
Peter Hitchcock,

We anticipate some travel support for early-career scientists will be available, and remote participation will also be possible.

This workshop replaces the QBO@60+ workshop originally scheduled for July 2020 at the Met Office in Exeter, UK.

Scientific organising committee: James Anstey, Neal Butchart, Clara Orbe, Yoshio Kawatani, Scott Osprey, Yaga Richter, Corwin Wright.

The event will showcase a variety of clean air-focused organizations and initiatives working in non-profit, academic, and for-profit settings. You can learn about their missions and resources and opportunities they offer to the research community, and what they might need from researchers. And there will be plenty of time to network with the larger community passionate about working toward cleaner air. There will be complimentary appetizers and drinks.

See you there!
