Vision for the WMO Integrated Global Observing System in 2040
This document provides high-level targets to guide the evolution of the World Meteorological Organization (WMO) Integrated Global Observing System (WIGOS) in the coming decades. This vision (henceforth referred to as the “Vision for WIGOS in 2040” or simply the “Vision”) replaces the “Vision for the Global Observing System in 2025”, which was adopted by the Executive Council at its sixty-first session in June 2009. In many ways, the 2025 Vision foreshadowed the development of WIGOS, whereas the current document anticipates a fully developed and implemented WIGOS framework that supports all act ...

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No. 15: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2018
Measurements of the content of radiocarbon (14C) in atmospheric carbon dioxide (CO2) provide a unique way to discriminate between fossil fuel combustion and natural sources of CO2. Simultaneous observations of CO2 and 14C demonstrate the decline of 14C content in atmospheric CO2 caused by CO2 addition from fossil fuel combustion. This finding illustrates the importance of long-term measurements of atmospheric composition by laboratories involved in the WMO Global Atmosphere Watch (GAW) Programme in helping identify greenhouse gas emission sources.
Boletín sobre los gases de efecto invernadero - N°15: Estado de los gases de efecto invernadero en la atmósfera según las observaciones mundiales realizadas en 2018
Las mediciones del contenido de radiocarbono (14C) en el dióxido de carbono atmosférico (CO2) ofrecen una manera singular de distinguir entre la quema de combustibles fósiles y las fuentes naturales de CO2 . Las observaciones simultáneas de CO2 y 14C demuestran la disminución del contenido de 14C en el CO2 atmosférico provocada por la incorporación de CO2 procedente de la quema de combustibles fósiles. Este hallazgo pone de relieve la importancia de las mediciones a largo plazo de la composición atmosférica realizadas por los laboratorios que participan en el Programa de la Vigilancia de la At ...![]()
GAW Report, 248. Twelfth Intercomparison Campaign of the Regional Brewer Calibration Center Europe
The Izaña Atmospheric Research Center (IARC), which is part of the State Meteorological Agency of Spain (AEMET), represents a centre of excellence in atmospheric science. It manages four observatories in Tenerife, including the high altitude Izaña Observatory, which was inaugurated in 1916 and has since carried out uninterrupted meteorological and climatological observations and become a WMO Centennial Station.
This report summarizes the many activities of the Izaña Atmospheric Research Center.
