Atmospheric composition Clause Samples
The 'Atmospheric composition' clause defines the specific makeup of gases and particulates present in a given environment, such as air within a facility, laboratory, or controlled space. It typically outlines acceptable levels or ranges for components like oxygen, nitrogen, carbon dioxide, and trace gases, and may set thresholds for contaminants or pollutants. This clause ensures that the environment meets safety, health, or operational standards, thereby protecting occupants and equipment and maintaining compliance with regulatory requirements.
Atmospheric composition. CAMS obtain data through the WMO GTS, from direct upload/download to/from FTP servers by collaborating organisations/projects/infrastructures (e.g. NILU, IAGOS, ACTRIS) and by download from databases on the web (e.g. AERONET, NDACC, WOUDC, WDCGG). The data formats include BUFR, NASA ▇▇▇▇, CSV, NetCDF and many others. The timeliness also varies from minutes to years. CAMS mostly rely on the observation networks to do the quality control. In order to support that process, CAMS has dedicated contracts (or is setting these up) with some of the major in situ networks and infrastructures (Integrated Carbon Observation System - ICOS, Network for the Detection of Atmospheric Composition Change - NDACC, In-Service Aircraft for a Global Observing System - IAGOS, EEA, European Aeroallergen Network - EAN, WMO-▇▇▇, The Aerosols, Clouds and Trace gases Research Infrastructure – ACTRIS/EMEP). CAMS has also established some agreements with non- European partners, most notably with Environment Canada. Through the CAMS_84 contract on Evaluation and Quality Control there is some effort to make the processing of the various data formats more efficient.
