<p>Das CM SAF (EUMETSAT Satellite Application Facility on Climate Monitoring) produziert, archiviert und stellt unter https://www.cmsaf.eu langjährige satellitenbasierte Klimadatensätze von vielen GCOS Essential Climate Variables (ECVs, essentielle Klimavariablen) bereit, die inzwischen auch die komplette aktuelle WMO Klimareferenzperiode 1990-2020 abdecken und damit eine gute Grundlage für die Analyse von Klimavariabilität und Klimawandel liefern. Seit 1999 hat das CM SAF kontinuierlich eine nachhaltige Infrastruktur zur Erzeugung von Klimadatensätzen aufgebaut, mit der Zeitreihen in hoher Qualität in einer operationellen Umgebung erzeugt werden, die auch aktuelle wissenschaftliche Entwicklungen berücksichtigen.</p> <p>Der inhaltliche Fokus des CM SAF liegt auf ECVs, wie Wolken, Wasserdampf, Niederschlag, Landoberflächentemperatur oder der Strahlungskomponenten (langwellig/kurzwellig) am Erdboden und am Oberrand der Atmosphäre, die durch GCOS (Global Climate Observing System) definiert wurden und im Zusammenhang mit dem globalen Energie und Wasser Kreislauf stehen. Einerseits nutzt das CM SAF dazu polarumlaufende Satelliten mit einer globalen räumlichen Abdeckung. Andererseits werden vom CM SAF für Afrika und Europa, Klimadatensätze für Wolken und Strahlung  basierend auf den zeitlich hochaufgelösten Messungen der METEOSAT-Instrumente erzeugt.</p> <p>Alle Daten des CM SAF werden kostenlos abgebeben, sind umfangreich dokumentiert und unabhängig extern begutachtet, um eine hohe Qualität zu gewährleisten. Dies wird unterstützt durch einen umfassenden Service für Kunden, indem beispielsweise Trainingsworkshops und andere Aktivitäten angeboten werden.</p> <p>Diese Präsentation wird einen Überblick über die aktuellen und geplanten Aktivitäten des CM SAF geben und soll interessierten Nutzern durch beispielhafte Anwendungen den Umgang mit CM SAF Produkten verdeutlichen. Zudem werden zukünftige mögliche Anwendungen der Datensätze aufgezeigt. </p>

Climate research, monitoring, prediction, and related services rely on accurate observations of the atmosphere, land, and ocean, adequately sampled globally and over sufficiently long time periods. The Global Climate Observing System, set up under the auspices of United Nations organizations and the International Council for Science to help ensure the availability of systematic observations of climate, developed the concept of essential climate variables (ECVs). ECV data records are intended to provide reliable, traceable, observation-based evidence for a range of applications, including monitoring, mitigating, adapting to, and attributing climate changes, as well as the empirical basis required to understand past, current, and possible future climate variability. The ECV concept has been broadly adopted worldwide as the guiding basis for observing climate, including by the United Nations Framework Convention on Climate Change (UNFCCC), WMO, and space agencies operating Earth observation satellites. This paper describes the rationale for these ECVs and their current selection, based on the principles of feasibility, relevance, and cost effectiveness. It also provides a view of how the ECV concept could evolve as a guide for rational and evidence-based monitoring of climate and environment. Selected examples are discussed to highlight the benefits, limitations, and future evolution of this approach. The article is intended to assist program managers to set priorities for climate observation, dataset generation and related research: for instance, within the emerging Global Framework for Climate Services (GFCS). It also helps the observation community and individual researchers to contribute to systematic climate observation, by promoting understanding of ECV choices and the opportunities to influence their evolution.

<p>Total Solar Irradiance (TSI) is one of the Essential Climate Variables (ECV) identified by the World Meteorological Organization's Global Climate System (GCOS). The Compact Lightweight Absolute RAdiometer (CLARA) experiment onboard the Norwegian micro satellite NorSat-1 is a SI traceable radiometer and was launched July 14, 2017 with the primary science goal to measure TSI from space. We present the latest status of the data and degradation correction obtained with this SI-traceable radiometer. Besides TSI, CLARA also measures the total outgoing radiation (TOR) at the top of the Earth atmosphere on the night side of Earth, which is extremely important to understand the Earth Radiation Budget. It is to our knowledge the first time that TSI and the emitted radiation from Earth are measured simultaneously with one SI-traceable absolute radiometer. We will compare the CLARA TSI and TOR time series with other available datasets. Ultimately, we aim towards determining the Earth Energy Imbalance from space. We will discuss the achievements and limitations in direction of this goal.</p>

Climate has been recognized to have direct and indirect impact on society and economy, both in the long term and daily life. The challenge of understanding the climate system, with its variability and changes, is enormous and requires a joint long-term international commitment from research and governmental institutions. An important international body to coordinate worldwide climate monitoring efforts is the World Meteorological Organization (WMO). The Global Climate Observing System (GCOS) has the mission to provide coordination and the requirements for global observations and essential climate variables (ECVs) to monitor climate changes. The WMO-led activity on Sustained, Coordinated Processing of Environmental Satellite Data for Climate Monitoring (SCOPE-CM) is responding to these requirements by ensuring a continuous and sustained generation of climate data records (CDRs) from satellite data in compliance with the principles and guidelines of GCOS. SCOPE-CM represents a new partnership between operational space agencies to coordinate the generation of CDRs. To this end, pilot projects for different ECVs, such as surface albedo, cloud properties, water vapor, atmospheric motion winds, and upper-tropospheric humidity, have been initiated. The coordinated activity on land surface albedo involves the operational meteorological satellite agencies in Europe [European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT)], in Japan [the Japan Meteorological Agency (JMA)], and in the United States [National Oceanic and Atmospheric Administration (NOAA)]. This paper presents the first results toward the generation of a unique land surface albedo CDR, involving five different geostationary satellite positions and approximately three decades of data starting in the 1980s, and combining close to 30 different satellite instruments.
