The continued increase of anthropogenic pressure on the Earth's ecosystems is degrading natural environment and then decreasing services it provides to humans. type, quantity, quality many those are directly connected land cover, yet competing demands for continue drive rapid cover change, affecting ecosystem services. Accurate updated information thus more important than ever, however, despite its importance, needs users remain only partially attended. A key underlying reason this that user...
Abstract The Copernicus Climate Change Service (C3S) provides open and free access to state-of-the-art climate data tools for use by governments, public authorities, private entities around the world. It is fully funded European Union implemented Centre Medium-Range Weather Forecasts (ECMWF) together with in Europe elsewhere. With over 120,000 registered users worldwide, C3S has rapidly become an authoritative service beyond, delivering quality-assured information based on latest science....
Recent work on bryophyte diversity in lowland forests of northern South America has suggested the existence a new type cloud forest, 'tropical forest' (LCF). LCF occurs river valleys hilly areas with high air humidity and morning fog, is rich epiphytes. We explored epiphyte abundance canopy microclimate area (200–400 m asl) near Saül, central French Guiana. analyzed vertical distribution epiphytic cover biomass 48 trees, rain forest (LRF) without fog. Trees had significantly more than LRF;...
In November 2016, the Paris Agreement entered into force calling Parties to strengthen their cooperation for enhancing adaptation and narrowing gap between climate science policy. Moreover, change has been identified as a central challenge sustainable development by United Nations 2030 Agenda Sustainable Development. Data provide basis reliable scientific understanding knowledge well foundation services that are required take informed decisions. consequence, there is an increasing need...
Abstract. Reanalysis near-surface wind fields from multiple reanalyses are potentially an important information source for energy applications. Inter-comparing via employing independent observations can help to guide users useful spatio-temporal scales. Here we compare the statistical properties of speeds observed at 210 traditional meteorological stations over Germany with reanalyses' fields, confining analysis recent years (2007 2010). In this period, station time series in be expected...
A land‐cover classification is needed to deduce surface boundary conditions for a soil–vegetation–atmosphere transfer (SVAT) scheme that operated by geoecological research unit working in the Andes of southern Ecuador. Landsat Enhanced Thematic Mapper Plus (ETM+) data are used classify distinct vegetation types tropical mountain forest. Besides hard classification, soft technique applied. Dempster–Shafer evidence theory analyse quality spectral training sites and modified linear unmixing...
• Additional water supplied by dew formation is an important resource for microbes, plants and animals in precipitation-limited habitats, but has received little attention tropical forests until now. We evaluated the micro-environmental conditions of tree stem surfaces their epiphytic organisms a neotropical forest, present evidence novel mechanism diurnal on these midday that physiological implications corticolous epiphytes such as lichens. In understorey lowland forest French Guiana, heat...
Recent evidence is emerging that tropical cloud forests are not restricted to mountains, but may also be found in lowland areas, the so-called 'tropical forest' (LCF). LCF occurs river valleys with high air humidity and morning fog, rich epiphytes. We explored diversity of bark-inhabiting liverworts LCF, a group organisms known sensitive indicators humidity. To test hypothesis differs species richness composition from rain forest without fog (LRF), we sampled liverwort LRF on 48 whole trees...
Abstract A worldwide online survey about user awareness of reanalyses and climate services was conducted in the period from November 2013 to February 2014 by Coordinating Earth Observation Data Validation for Re-Analysis Climate Services (CORE-CLIMAX) project. The 2,578 respondents were mostly users global [particularly European Centre Medium-Range Weather Forecasts (ECMWF), National Centers Environmental Prediction (NCEP), Aeronautics Space Administration (NASA), Japan Meteorological Agency...
Abstract If climate services are to lead effective use of information in decision-making enable the transition a climate-smart, climate-ready world, then question trust products and is paramount importance. The Copernicus Climate Change Service (C3S) has been actively grappling with how build such trust: provision demonstrably independent assessments quality products, which was deemed an important element trust-building processes. C3S provides access essential variables (ECVs) from multiple...
In this study, two different methods were applied to derive daily and monthly sunshine duration based on high-resolution satellite products provided by the European Organisation for Exploitation of Meteorological Satellites (EUMETSAT) Satellite Application Facility Climate Monitoring using data from Meteosat Second Generation (MSG) SEVIRI (Spinning Enhanced Visible Infrared Imager). The either hourly cloud type or surface incoming direct radiation. estimates not found be significantly native...
This study presents a method for adjusting long-term climate data records (CDRs) the integrated use with near-real-time using example of surface incoming solar irradiance (SIS). Recently, 23-year long (1983–2005) continuous SIS CDR has been generated based on visible channel (0.45–1 μm) MVIRI radiometers onboard geostationary Meteosat First Generation Platform. The is available from EUMETSAT Satellite Application Facility Climate Monitoring (CM SAF). Here, it assessed whether homogeneous...
Abstract. A web-based survey to assess the benefits and gaps in reanalyses as part of growing climate services was carried out 2013–2014. The elicited responses from about 2500 users information. One eleven points specifically addressed observations used reanalysis, with a multiple-choice question "Have you reanalysis input feedback data?". Almost half respondents admitted not knowing what such data were about. Among others, specific queries asked for these be made available more openly....
Data from a variety of research programmes are increasingly used by policy makers, researchers, and private sectors to make data-driven decisions related climate change variability. Climate services emerging as the link narrow gap between science downstream users. The Global Framework for Services (GFCS) World Meteorological Organization (WMO) offers an umbrella development has identified quality assessment, along with its use in user guidance, key aspect service provision. This extra...
Since its official launch in 2018 supporting the implementation of Copernicus Climate Change Service (C3S), Data Store (CDS) software infrastructure has evolved many ways driven by an expanding catalogue resources, a growing user community and evolution technologies standards. On 2020 twin instance, Atmosphere (ADS), as support Monitoring (CAMS) was released. then, Infrastructure renamed (CADS). Combined, CDS ADS, provide nowadays service to more than 270k registered users, delivering over...
Abstract This paper describes the vision and objectives for evaluation quality control of datasets available on Climate Data Store (CDS) Copernicus Change Service (C3S). The CDS is a cloud service providing reliable, open, free access to climate from many different sources, including observations derived data records, global regional reanalysis products, output models. information are widely used monitor change, policy development, environmental impact studies, business plans, public...
Abstract. The World Meteorological Organization (WMO) established Regional Climate Centres (RCCs) around the world to create science-based climate information on a regional scale within Global Framework for Services (GFCS). paper introduces satellite component of WMO Centre Monitoring (RCC-CM) Europe and Middle East. RCC-CM product portfolio is based essential variables (ECVs) as defined by Observing System (GCOS), spanning atmospheric (radiation, clouds, water vapour) terrestrial domains...
