Ocean colour is recognised as an Essential Climate Variable (ECV) by the Global Observing System (GCOS); and spectrally-resolved water-leaving radiances (or remote-sensing reflectances) in visible domain, chlorophyll-a concentration are identified required ECV products. Time series of products at global scale high spatial resolution, derived from ocean-colour data, key to studying dynamics phytoplankton seasonal inter-annual scales; their role marine biogeochemistry; carbon cycle; modulation...
In this work, trend estimates are used as indicators to compare the multi-annual variability of different satellite chlorophyll-a (Chla) data and assess fitness-for-purpose multi-mission Chla products climate records (CDR). Under assumption that single-mission free from spurious temporal artifacts can be benchmark time series, CDRs should reproduce main patterns observed by series when computed over their respective periods. This study introduces applies quantitative metrics distributions...
Abstract. A compiled set of in situ data is important to evaluate the quality ocean-colour satellite-data records. Here we describe for validation products from ESA Ocean Colour Climate Change Initiative (OC-CCI). The were acquired several sources (MOBY, BOUSSOLE, AERONET-OC, SeaBASS, NOMAD, MERMAID, AMT, ICES, HOT, GeP&CO), span between 1997 and 2012, have a global distribution. Observations following variables compiled: spectral remote-sensing reflectances, concentrations...
Abstract. A global in situ data set for validation of ocean colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version compilation, starting 1997, now extends to 2021, which important most recent satellite optical sensors such as Sentinel 3B OLCI and NOAA-20 VIIRS. The comprises observations following variables: spectral remote-sensing reflectance, concentration chlorophyll-a, inherent properties, diffuse attenuation coefficient, total suspended...
The ULCOS blast furnace process aims at reducing the CO<sub>2<sub/> emission of by 50% in two steps: Decrease carbon consumption recycling most top gas after removal, which requires operating with pure oxygen; Underground storage CO<sub>2<sub/>. first stage is essential to demonstrate feasibility this new process. It has been tested over a 6 week campaign LKAB experimental BF Luleå. facility was adapted specifically for trials (including erection VPSA plant). Different conditions were...

The Ocean-Colour Climate-Change Initiative (OC-CCI) aims to create a long-term, consistent, error-characterised time series of ocean-colour products, for use in climate change studies. Climate Change is programme the European Space Agency devoted using satellites generate quality data Essential Variables (ECVs) identified by Global Observing System (GCOS). Within ocean colour CCI project, user consultation was undertaken, targeting both modelling community and Earth Observation community....
The uncertainties associated with MERIS remote sensing reflectance (RRS) data derived from the SeaWiFS Data Analysis System (SeaDAS) are assessed field observations. In agreement strategy applied for other sensors, a vicarious calibration is conducted using in situ Marine Optical BuoY offshore Hawaii, and leads to adjustment factors departing 1 by 0.2% 1.6%. three sets used validation have been collected at fixed stations northern Adriatic Sea Baltic Sea, variety of European waters Baltic,...
High-biomass harmful algal blooms can kill farmed fish through toxicity, physical effects or de-oxygenation of the water column. These often form over spatially large areas meaning that Earth observation is well placed to monitor and study them. In this letter, we present a statistical-based background subtraction technique has been modified detect high-biomass blooms. The method builds upon previous work uses statistical framework combine spatial temporal information produce maps bloom...
Recognising people by their gait is a biometric of increasing interest. Recently, analysis has progressed from evaluation few techniques on small databases with encouraging results to large and still results. The potential as was encouraged the considerable amount evidence available, especially in biomechanics literature. This motivated development new databases, technique more rigorous procedures. We adumbrate some we have developed gain insight into for biometric. In particular, consider...

In Australia, many birds and arboreal animals use hollows for shelters, but studies predict shortage of in near future. Aged dead trees are more likely to contain therefore automated detection them plays a substantial role preserving biodiversity consequently maintaining resilient ecosystem. For this purpose full-waveform LiDAR data were acquired from native Eucalypt forest Southern Australia. The structure the significantly varies terms tree density, age height. Additionally, Eucalyptus...
Abstract. The overarching aim of this paper is to enhance the visualisations and classifications airborne remote sensing data for forest surveys. A new open source tool presented aligning hyperspectral full-waveform LiDAR data. produces coloured polygon representations scanned areas aligned metrics from both datasets. Using provided by NERC ARSF, tree coverage maps are generated projected into polygons. 3D meshes show well-separated structures suitable direct rendering with commodity...
