About Me
I am an experienced aeronautical meteorologist with a three‑decade career spanning national and international roles, including positions with the United Kingdom Met Office, the International Civil Aviation Organization (ICAO) and the World Meteorological Organization (WMO). See my career highlights.
I founded Greg Brock Consulting in 2026 to provide independent, authoritative support to the aeronautical meteorological community — regulatory authorities, service providers and users — as they address a multitude of meteorological, regulatory and operational challenges and opportunities.
My expertise covers the full spectrum of aeronautical meteorology — from observations, forecasts and warnings for airports, terminal areas and en‑route operations, to aeronautical climatology and the impacts of climate change on aviation.
Alongside my technical background, I bring strong planning, organisational and coordination skills, supported by an deep understanding of evolving scientific and technological capabilities, emerging aviation user needs, and the international standards‑making processes that shape the global aeronautical meteorology system.
To empower aeronautical meteorological services to operate with greater efficiency and impact, and to help aviation stakeholders better understand how to integrate weather and climate intelligence into their decision‑making so that the aviation ecosystems operates safer, smarter and more sustainably.
My Mission
Career highlights
Between 2016 and 2025, I led WMO’s aeronautical meteorology programme, managing resources, guiding global implementation and supporting Members through training and outreach. I oversaw WMO's Commission for Aeronautical Meteorology and Standing Committee on Services for Aviation, maintained international regulations and other technical documentation, and worked closely with ICAO, IATA and other global and regional partners. I represented WMO on key ICAO panels, supported ISO‑aligned quality management practices, organised global scientific and technical events and supervised a small specialist team.
Between 2009 and 2016, I managed ICAO's global and regional meteorology programmes, aligning work with the Global Air Navigation Plan (GANP) and Global Aviation Safety Plan (GASP) while advising Council and Commission, senior leadership and others on regulatory, operational and technical matters. I supported numerous expert groups, advanced ICAO Annex 3 and related provisions, collaborated closely with WMO and other industry partners, supported States through guidance and implementation activities, oversaw high‑profile technical meetings, produced ICAO‑standard documentation and supervised multidisciplinary teams.
Between 1997 and 2009, I managed the daily operations of the SADIS (SAtellite DIStribution System for Information Related to Air Navigation) and supported WAFC and VAAC operations, working closely with the UK Civil Aviation Authority and NATS on regulated MET services. I analysed aviation modernisation trends, supported States with implementation, contributed to ICAO expert groups, and produced technical documentation. While working as a forecaster I delivered a wide range of aviation weather products, provided briefing services to flight crew and ATC personnel, led situation analyses, and maintained quality and operational procedures.
