Membership call

Apply to be a member of Global Precipitation EXperiment (GPEX). 

Last date to apply: 28 April 2024

The World Climate Research Programme (WCRP) Lighthouse Activities are transdisciplinary in nature, integrating across WCRP and collaborating with partners, to accelerate advances in new science, technologies, and institutional frameworks that are needed to more effectively manage climate risks and minimize societal threat based on robust and actionable climate information.

The current interim Scientific Steering Group (SSG) of the Global Precipitation Experiment (GPEX) Lighthouse Activity has developed its Science Plan (as of November 2023). The purpose of this Open Call is to seek nominations (including self-nomination) to the SSG and four Working Groups (WG1: Coordinated Field Campaigns; WG2: Data Development; WG3: Prediction and Modeling; WG4: Regional/National Activities and Capacity Development; See more details below) ) that will develop and execute the GPEX implementation plan over the next decade, provide guidance for the WGs, and integrate with the past efforts.

GPEX will have a diverse SSG composed of approximately ten members including two co-chairs. Similarly, each diverse WG is formed by approximately ten members including two co-chairs. WG co-chairs will be invited to all SSG meetings for discussions and decision-making, following the successful GEWEX practice. At least one Early and Mid-Career Researchers (EMCR) is anticipated to join the SSG and each WG. Gender and geographic balances will also be emphasized.


  • SSG Membership – Contribute scientific knowledge, experience and energy to achieve the goals of GPEX and provide guidance for the WGs, working with other WCRP activities and partners, as necessary.
  • WG Membership - Contribute scientific knowledge and energy to meet the objectives and proposed outcomes of the WG, working with other members of the WG, the GPEX SSG, and other WCRP activities and partners, as necessary.

Time commitment

Hourly meetings are expected to take place regularly on a bi-monthly or monthly basis for the SSG and for the WGs, at the discretion of the SSG co-chairs and WG co-leads. There may be times when there is more or less work, depending on the activities undertaken. Most meetings will be online, with some out-of-hours work required due to time zone coordination. A face-to-face meeting is anticipated every 18 months.


These are not paid roles.
