The Contrail Forecast Verification Experiment (COVEX) was a Met Office experiment to validate the new contrail forecasting techniques based on engine parameters and environmental conditions. It was based on a one-flight experiment on board the Facility for Airborne Atmospheric Research (FAAM) aircraft, that took place in December 2004.

This dataset collection contains Chemical Ablation Model version 3 (CABMOD3) simulations of metal ablation from meteoroids and Meteoric Ablation Simulator (MASI) sodium and nickel ablation experimental data. This experiment was undertaken as part of Natural Environment Research Council (NERC) First study of the global Nickel and Aluminium Layers in the upper atmosphere (NIALL) project (NE/P001815/1). This project aimed to make the first ever study of Ni and Al chemistry in the mesosphere/lower thermosphere.

Skin Sea Surface Temperature data from the (A)ATSR Validation Campaign by SISTeR. The prime objective of the (A)ATSR mission is to return accurate measurements of the global sea surface temperature. To ensure the accuracy of the measurement, there have been joint efforts to validate the data. One of these efforts is the (A)ATSR Validation Campaign which involves the deployment of the Scanning Infrared Sea surface Temperature Radiometer (SISTeR). The SISTeR is a self-calibrating radiometer that measures the skin sea surface temperature. The SISTeR was mounted on MS Color Festival and MS Prinsesse Ragnhild to return skin sea surface temperature in the North Sea in 2006, and was on-board RMS Queen Mary 2 collecting data from the Atlantic Ocean, Indian Ocean and Western Pacific between 2010 and 2014. Data was collected continuously throughout the cruises unless severe weather conditions required the instrument to be protected, which results in the prevention of the data collection.

The Met Office NU-WAVE (Ice Nuclearisation in Wave Clouds) project aimed at studying ice crystal nucleation in orographic wave clouds. NU_WAVE was to study the nucleation of ice crystals in orographic wave clouds and its dependence on the physical and chemical properties of the input aerosol. The primary aim was to study heterogeneous nucleation processes acting in the temperature range 0 to -35C (but principally -15 to -35C). Where possible, however, the influence of homogeneous nucleation a temperatures colder than -35C were also studied. It was based on a 2-flight campaign (November 2004) on board the FAAM aircraft. Flights involved penetration of single wave clouds, trains of wave clouds and extensive sheets of cirrus formed by orographic effects.

Monthly global surface ozone concentration and ozone dry deposition flux fields from models participating in the UN/ECE Task Force on Hemispheric Transport of Air Pollution (TF HTAP) intercomparison. Models were driven by meteorological fields for the year 2001. Data are regridded to a consistent 3 x 3 degree resolution and saved in NetCDF format.

These data are held by the BADC for the Natural Environment Research Council (NERC) Molecular Spectroscopy Facility (MSF). MSF provides world-class scientific equipment and support for infrared (IR),visible, and ultraviolet (UV) spectroscopy. The MSF laboratories are used by many UK and international customers in a wide range of research and development programmes. The data are spectra of various atmospheric gases. These data are public. The data held covers the following areas: Water vapour line parameters Molecular oxygen absorption cross-sections Molecular oxygen/nitrogen absorption cross-sections Hydrofluorocarbon (HFC) infrared absorption cross-sections Perfluorocarbon (PFC) infrared absorption cross-sections Computer software

This is the high frequency (10 Hz) eddy covariance (EC) measurements which mainly contain the wind data, ship motion data, gas concentration data and the underway measurements. These data were measured on summer 2019 during two Arctic cruises JR18006 (from and to Aberdeen, UK and visited the Barents Sea ) and JR18007 (from Harwich, UK to Svalbard and visited the Greenland Sea). These EC data can be used to directly calculate the air-sea CO2 and sensible heat fluxes. The EC system was deployed on RRS James Clark Ross by Thomas Bell and Mingxi Yang (Plymouth Marine Laboratory). Please see Dong et al., (2021) for details of these EC data. Eddy covariance air-sea CO2 flux measurements were made possible by funding from the NERC ORCHESTRA (NE/N018095/1) and European Space Agency AMT4oceanSatFluxCCN (4000125730/18/NL/FF /gp) projects.

A new version of this dataset exists. To see the last version of the Antarctic Digital Database, have a look here: https://data.bas.ac.uk/collections/e74543c0-4c4e-4b41-aa33-5bb2f67df389/ Coastline for Antarctica created from various mapping and remote sensing sources, provided as polygons with ''land'', ''ice shelf'', ''ice tongue'' or ''rumple'''' attribute. This dataset has been generalised from the high resolution vector polygons. Covering all land and ice shelves south of 60S. Suitable for topographic mapping and analysis. Data compiled, managed and distributed by the Mapping and Geographic Information Centre and the UK Polar Data Centre, British Antarctic Survey on behalf of the Scientific Committee on Antarctic Research. Major changes in v7.4 include updates to coastline and ice shelves between Gipps Ice Rise and Ronne Ice Shelf, updated ice shelf fronts for Brunt, Stange and West ice shelves, Pine Island Glacier, and an updated coastline for Adelaide Island.

Datasets from a shallow water mooring deployed in the Southern Ocean, north of South Georgia in January 2006 during the marine cruise JR140 and recovered in April 2006 by the marine cruise JR146.

During field work in 2001 over 1600 specimens were collected from four main fossil plant assemblages: the ''Nordenksjold flora'' from the Cross Valley Formation of Late Palaeocene age; and 3 floras from La Meseta Formation i) Flora2 from the Valle De Las Focas allomember, ~late Early Eocene, ii) Wiman Flora, Acantilados allomember, late Early/mid Eocene, iii) Cucullaea 1, Cuculleae 1 allomember Flora, early Late Eocene. In addition smaller collections of fossils from other parts of the La Meseta Formation were collected. The work concentrated on the Late Palaeocene and the Cuculleae 1 floras as these were the best preserved and had sufficient morphotypes for climate analysis. In the Late Palaeocene flora 36 angiosperm leaf morphotypes were identified, along with 2 pteridophytes (ferns), and podocarp and araucarian conifers. Discovery of several new leaf types indicates that the Tertiary floras from Antarctica were more diverse than previously thought.
