HadISD data format description
No full textThis document provides data format information for the Met Office Hadley Centre (MOHC) HadISD data. The document contains information on the NetCDF structure, the variable abbreviations and corresponding names and the global attributes
NERC-ARSF-DAN Hyperspectral data quality report 2015.
No full textThe Airborne Research and Survey Facility (ARSF) collect hyperspectral data with a Specim AISA Fenix instrument, operated since 2014. The Fenix instrument comprises two detectors covering the Visible to Near Infra-Red (VNIR) and Short Wave Infra-Red (SWIR) regions, giving a total spectral
range of 380–2500 nm. This data quality report describes issues for hyperspectral data acquired with the Fenix instrument that should be considered when further processing any ARSF datasets acquired from 31 August 2014 until the end of 2015

NERC-ARSF-DAN Thermal Hyperspectral data quality report 2015
No full textThe Airborne Research and Survey Facility (ARSF) collect thermal data with a Specim AISA Owl instrument, operated since 2014. The Owl instrument covers wavelengths from 7.6 – 12.3 μm. A pair of black bodies, which are mechanically moved in front of the sensor lens one by one, are used for calibration. This data quality report describes issues for thermal data acquired with the Owl instrument that should be considered when further processing any ARSF datasets acquired in 2015

HadISDH Update Document version 2.1.0.2015p
No full textUpdate notes for version 2.1.0.2015p. The HadISDH.v2.1.0.2015p contains all 12 months of 2015, a minor code change to the homogenisation software and some historical changes to the data due to source archive changes and minor changes to applied homogeneity adjustments due to sensitivity to both the historical changes and additional 12 months of data. More information can be found in the HadISDH.v2.1.0.2015p_Update_Document.pdf (LINK) and at

Marine safety Environmental Risk and Reliability Series
No full textMarine vessel collisions cover the largest part of accidents scenario in waterways.
Waterways accidents expose vessel owners and operators as well as the public to risk. They attract possibility of losses such as vessel cargo damage, injuries, loss of life, environmental damage and obstruction of waterways. Collision risk is a product of the probability of the physical event its occurrence as well as losses of various nature including economic losses.
Environmental problem and need for system reliability call for innovative methods and tools to assess and analyze extreme operational, accidental and catastrophic scenarios as well as accounting for the human element and integrate these into a design environments part of design objectives. This paper discusses modeling of waterways collision risk frequency in waterways. The analysis considers mainly the waterways dimensions and other related
variables of risk factors like operator skill, vessel characteristics, traffic characteristics,
topographic, environmental difficulty of the transit and quality of operator’s information in
transit which is required for decision support related to efficient, reliable and sustainable
waterways developments. The probability per year predicted is considered acceptable in
maritime and offshore industry but for a channel using less number of expected traffic,
it could be considered high. Providing safety facilities like traffic separation, vessel traffic
management could restore maximize sustainable use of the channel
