Atmospheric Observation Panel for Climate (AOPC)
The Atmospheric Observation Panel for Climate was established by the GCOS Steering Committee in recognition of the need for specific scientific and technical input concerning atmospheric observations for climate. The Joint Scientific Committee of the World Climate Research Programme, recognizing the benefits of the AOPC, agreed in 1995 to co-sponsor the panel, which was therefore renamed as the GCOS/WCRP Atmospheric Observation Panel for Climate.
- Assessing the current state of the atmospheric component of the global observing system for climate, and identifying its gaps and inadequacies;
- Securing the implementation of designated GCOS networks and promoting the establishment and enhancement of other systems to provide long-term and consistent data and information for atmospheric ECVs, such as Earth radiation budget, Surface radiation, Greenhouse gases, Water vapour, Cloud properties, and Aerosols;
- Liasing with relevant research, operational and end-user bodies in order to determine and maintain the requirements for data to monitor, understand and predict the dynamical, physical and chemical state of the atmosphere and its interfaces on seasonal to multi-decadal timescales, on both global and regional levels;
- Promoting the transfer and accessibility of data to the user community, as well as the rehabilitation of historical observational and proxy climate datasets.
Terms of Reference
The goal of the AOPC is to plan and promote the atmospheric component of GCOS. Its specific Terms of Reference are as follows:
- To liaise with relevant research, operational and end-user bodies in order to determine and maintain the requirements for data to monitor, understand and predict the dynamical, physical and chemical state of the atmosphere and its interfaces on seasonal to multi-decadal time scales, on both global and regional levels.
- To promote the establishment and maintenance of an overall system to provide long-term, high-quality, consistent data and information to meet those requirements.
- To review the current state of the atmospheric component of the global observing system for climate.
- To identify gaps and inadequacies in the atmospheric component of the current global observing system for climate.
- To propose and promote the establishment of new systems, or enhancements to current systems and practices, to eliminate deficiencies.
- To promote the transfer, as appropriate, of research observing systems to operational networks.
- To promote the rehabilitation of historical observational and proxy climate data sets.
- To promote and review institutional arrangements to ensure that:
- GCOS observations are of the highest quality and are collected in accordance with the highest standards of practice;
- GCOS data products are relevant and of the highest quality;
- GCOS data are archived and accessible to the user community.
- To liaise with the other GCOS panels, WCRP steering groups and other relevant entities, such as WMO Commissions and CEOS, on atmospheric climate observing system issues.
- To carry out agreed assignments from the GCOS Steering Committee.
- To report regularly to the GCOS SC and the JSC for WCRP on issues related to the atmospheric component of GCOS.
Members of the panel participate in several working groups assigned particular tasks. These are:
- AOPC on the GCOS Reference Upper-Air Network (WG-GRUAN); and
- AOPC/OOPC Working Group on Surface Pressure (WG-SP).
Adivisory Group on GSN and GUAN (AGG)
The AOPC Advisory Group on GSN (GCOS Surface Network) and GUAN (GCOS Upper-air Network) (AGG) assesses the developments of these two essential climatological networks and makes recommendations for improvements of specific stations, station density, data quality and availability of the existing networks and the data distributed.
