Report on FIDUCEO project MVIRI Aerosol demonstration dataset
Full text linkThis document forms the deliverable D5.8 to report on the climate data record (CDR) of aerosol optical thickness (AOT) as retrieved from the MVIRI fundamental climate data record (FCDR) [RD 1, RD 2, RD 3] using the Combined Inversion of Surface and AeRosol (CISAR) Algorithm [RD 4]. The primary objective of this data record is to assess and demonstrate how the recalibrated and uncertainty-quantified MVIRIFCDR can support improved retrieval of geophysical parameters. Of particular interest is the impact of in-flight reconstructed and spectrally degrading spectral response functions

EUSTACE Product User Guide and quick start guide, draft version 0.8
Full text linkThis Product User Guide (PUG) is meant as a practical guide for the data products of the EUSTACE (EU Surface Temperature for All Corners of Earth) project and to facilitate (potential) users in their exploitation of the EUSTACE datasets
FIDUCEO project: (Microwave): Report on the MW FCDR: Uncertainty
Full text linkThis document is one of the five documents that make up the D2-2 report on “traceability chains for FCDRs”. Since the original project proposal our thoughts have refined and while this document describes the “sequence of measurement standards and calibrations that is used to relate a measurement result to a reference” (the VIM definition of a traceability chain), it is not presenting this in the form of a chain. This document provides an overview of the uncertainty analysis for the analysed sensors along with the methods to establish metrological traceability for the developed FCDRs. This document is specifically about the MicrowaveFCDR (MHS, SSM-T2, AMSU-B). The document D2-2a provides an overview of the purposes of these documents and explains the basis of the effects tables
NCAS CDAO Sky-Camera Time-Lapse Video for 2009-03-25 17:25 UTC (showing Altocumulus fluctus and Altocumulus undulatus clouds followed by Altocumulus lenticularis)
No full textA time-lapse video showing Altocumulus fluctus and Altocumulus undulatus clouds followed by Altocumulus lenticularis. The short-lived fluctus cloud feature is caused by Kelvin-Helmholtz wave activity, which is generated where the wind speed changes sharply with altitude. The initial telephoto image shows the characteristic breaking-wave pattern. This was taken (at 17:37 UTC) at the same location as the camera used to to generate the video sequence, but shows a narrower field of view. The wave activity is also revealed by the Altocumulus undulatus cloud elements, which form in parallel bands. There is evidence of mountain wave activity throughout the sequence and Altocumulus lenticularis becomes the dominant cloud type towards the end. These clouds remain stationary relative to the landscape rather moving with the wind. Occasional contrails and Cirrus clouds can be seen at a higher level (one of the contrails develops undulatus features). These remain illuminated for longer than the Altocumulus clouds as the sun sets. This video has been created from images taken by the Sky-Camera at the National Centre for Atmospheric Science (NCAS) Capel Dewi Atmospheric Observatory (CDAO) near Aberystwyth, UK - formerly known as the Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility.

FIDUCEO project: Metrological assessment of consistency, stability and uncertainty of FIDUCEO FCDRs
Full text linkThis report addresses the assessment of the Fundamental Climate Data Records (FCDRs) using the methodologies developed under WP2 for mutual and relative consistency and stability (trend artefacts and step changes) both within and across sensor-series. Where possible the FCDR uncertainty information will be validated. Each sensor team has found it necessary to assess stability in different ways, because of the different context of different sensor series
FIDUCEO project: Product user guide –HIRS FCDR release 1.0
Full text linkThis document describes the v1.0 HIRS “easy” FCDR data files released in the autumn of 2019. The released data record contains nearly 40 years of data and can be considered the initial version of the FCDR, i.e. a data record long enough to generate climate data records (CDRs) for climate research. This guide gives: 1. An overview of the specifications of the data record; 2. Scientific records on the generation, definition, and algorithms of the data record; 3. Information on limitations of the current version of the data record; 4. Technical details on the format and on how to access the data
