FIDUCEO project: Principles behind the FCDR effects table
Full text linkThis document describes the FCDR effects tables being developed in the FIDUCEO project. It has the following aims: To describe what the effects table is, how it is to be filled in by FCDR developers and how it is anticipated to be used. To record (in appendices) the derivation of equations for the different correlation forms. It forms the basis of the overall deliverable D2-2, and has been developed in parallel with the sensor specific partner documents describing the effects tables for each of the 4 FCDRsin the FIDUCEO project
Extreme weather in the UK: past, present and future - event details from the TEMPEST database: data quality statement
No full textThis document provides a statement of the data quality within the TEMPEST (Tracking Extremes of Meteorological Phenomena as Experienced in Space and Time) database of extreme weather event narratives as detailed in primary archival sources
STFC Centre for Environmental Data Analysis (CEDA) Annual Report 2016 (April 2016-March 2017)
Full text linkThe mission of the Centre for Environmental Archival (CEDA) is to deliver long term curation of scientifically important environmental data at the same time as facilitating the use of data by the environmental science community.
CEDA was established by the amalgamation of the activities of two of the Natural Environment Research Council (NERC) designated data centres: the British Atmospheric Data Centre, and the NERC Earth Observation Data Centre, and consolidated annual reports have been produced since 2009. This annual report presents key statistics for the year past (2014- 2015) as well as a series of snapshots of activity, expressed as short highlights and short reports. Key data centre metrics are also provided.
This year was characterised by the major upgrade in JASMIN capability(JASMIN being the data intensive supercomputer which provides the fabric upon which CEDA and the CEDA services are delivered). As in the advent of JASMIN itself, in early 2012, this has had a major impact both on what CEDA can do, and the services that can be offered to the community — and the uptake in the community is clear to see in the statistics presented here. The consequences for CEDA itself are still being worked through, but it is clear that there is a significant expansion in the role of CEDA staff whose expertise must now embrace support for “big data” tools and algorithms by archive and other users on JASMIN. Notwithstanding this new role, as in previous years, CEDA staff are involved in nearly all the major atmospheric science programmes underway in the UK, in many earth observation programmes, and in a wide range of informatics activities.
Over the years we have reported our key partnerships, and as before, these revolve around our neighbours on the Harwell site (including the Satellite Applications Catapult, with whom we share delivery of the facility for Climate and Environmental Monitoring from Space, CEMS), the European Network for Earth Simulation (with whom we share the delivery of the European component of the Earth System Grid Federation), and many other project collaborators
NERC MSTRF Sky-Camera Time-Lapse Video for 2010-09-07 05:30 UTC (showing widespread development of Cumulonimbus clouds, some of which have extensive Anvils).
No full textA time-lapse video showing widespread development of Cumulonimbus clouds, some of which have extensive Anvils. A variety of other cumuloform clouds can be seen. The origin of the widespread cirrus cloud seen during the second half of the sequence is probably outflow from Cumulonimbus anvils. This video has been created from images taken by the NERC MST Radar Facility's Sky-Camera, which is located near Aberystwyth in West Wales.

FIDUCEO Project: (MVIRI): Report on the MVIRIFCDR: 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 MVIRIFCDR. The document D2-2a provides an overview of the effects tables

NERC MSTRF Sky-Camera Time-Lapse Video for 2010-09-07 16:50 UTC (showing Cumulonimbus cloud development at sunset).
No full textA time-lapse video showing Cumulonimbus cloud development at sunset. Most of the first Cumulonimbus cloud is obscured by the smaller Cumulus clouds in the foreground. Its anvil is clearly visible. Three further Cumulonimbus clouds cast crepuscular rays from the light of the setting sun. Their anvils merge together. This video has been created from images taken by the NERC MST Radar Facility's Sky-Camera, which is located near Aberystwyth in West Wales.
