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.

A collection of Version 2.0 datasets produced by the Ocean Colour project of the ESA Climate Change Inititative (CCI). The Ocean Colour CCI is producing long-term multi-sensor time-series of satellite ocean-colour data with a particular focus for use in climate studies. Data products being produced include: phytoplankton chlorophyll-a concentration; remote-sensing reflectance at six wavelengths; total absorption and backscattering coefficients; phytoplankton absorption coefficient and absorption coefficients for dissolved and detrital material; and the diffuse attenuation coefficient for downwelling irradiance for light of wavelength 490 nm. Information on uncertainties is also provided. This dataset collection refers to the Version 2.0 data products held in the CEDA archive and available from ftp://anon-ftp.ceda.ac.uk/neodc/esacci/ocean_colour/data/v2-release . Links to the individual datasets that make up this collection are given in the record below. Please note, version 3.0 data products are now currently available directly from the Ocean Colour CCI team (see link in the documentation section).

The Global Ocean Surface Temperature Atlas Plus (GOSTAplus) contains maps of Sea Surface Temperature (SST) climatologies and anomalies, Night Marine Air temperature climatologies and anomalies and Sea Ice coverage spanning the period 1851-1995. Dataset includes gridded, global SSTs from 1951-1990 and Sea Ice coverage from 1903 to 1994. The data are provided by the Met Office. Updated version of some data also available on request.

Historical and future simulations of sea surface elevation for UK waters for 1970-2100 produced by the Met Office for UK Climate Projections 2018 (UKCP2018). The data is available at hourly temporal resolution.

ACID-PRUF was a three year NERC directed programme that investigated the complex interaction of aerosols and clouds. The overall aims of ACID-PRUF were to reduce the uncertainty in the radiative forcing associated with the aerosol indirect effects though a targeted laboratory and modelling programme. This dataset collection contains measurements of freezing fraction of water solution droplets-solute and suspended matter during the immersion freezing of pollen extracts (birch pollen, Betula fontinalis occidentalis, Sigma-Aldrich, P6895-1G), with a new cold electrodynamic balance (CEDB).

Global and regional composite (Level 3) products of the MEdium Resolution Imaging Spectrometer (MERIS) Level 2 geophysical data are generated by the UK Multi-Mission Product Archive Facility (UK-MM-PAF)/Infoterra Ltd (Part of Astrium GEO-Information Services). One of these products: MERIS Terrestrial Chlorophyll Index (MTCI) data are available from NEODC. The products are in GEOTIFF format, on latitude-longitude geocoded grids, and are accompanied by an XML-metadata file and a JPEG browse image.

World Climate Research Programme (WCRP) Coupled Model Intercomparison Project Phase 6 (CMIP6): Collection of simulations from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) ACCESS-ESM1-5 model. The official CMIP6 Citation, and its associated DOI, is provided as an online resource linked to this record.

Infrared radiances from the Limb Infrared Monitor of the Stratosphere (LIMS) instrument, mounted on the Nimbus-7 satellite, were stored on a Radiance Archive Tape (RAT). RAT data was used to derive a series of products, two of which are held here. Firstly, the LIMS Inverted Profile Archival Tape (LAIPAT). This dataset contains radiances (from RAT), which are used to derive daily inverted profiles of temperature, and mixing ratios, water vapour, nitric acid, and nitrogen dioxide. Profiles are geolocated. Secondly, the LIMS Map Archival Tape (LAMAT). This dataset is processed to create daily maps in the form of Fourier coefficients for each parameter at 18 pressure levels (from 0.05 to 100 mbar). Data are organised into 38 4 deg. latitude bands. Data for the daily maps are interpolated to the two synoptic time (0000 GMT for night and 1200 GMT for day). Also included is the day/night combined (averaged) data. This dataset is public. Please note that a major reprocessing of the Nimbus 7 LIMS data has recently been completed. The purpose of this activity is to take advantage of the changes in the spectral line parameters that have occurred since the original archived version was created and to generate a data version that is compatible with the UARS data sets. Improvements in the algorithm have also been made. More information is available from the LIMS homepage at http://lims.gats-inc.com/ and version 6 data can be downloaded from GES DAAC.

The Landmap project features data collection consists of building heights, classes of buildings (including place names) for the main conurbations of the UK, and Kinematic GPS (KGPS) data for over 6,400km of roads. The Joint Information Systems Committee (JISC) funded Landmap service which ran from 2001 to July 2014 collected and hosted a large amount of earth observation data for the majority of the UK. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

This dataset collection contains air quality, greenhouse gas, Volatile Organic Compounds (VOCs) and surface meteorological measurements for the Kirby Misperton site and Little Plumpton. British Geological Survey (BGS), the universities of Birmingham, Bristol, Liverpool, Manchester and York and partners from Public Health England (PHE) and the Department for Business, Energy and Industrial Strategy (BEIS), are conducting an independent environmental baseline monitoring programme near Kirby Misperton, North Yorkshire and Little Plumpton, Lancashire. These are areas where planning permission has been granted for hydraulic fracturing. The monitoring allows the characterisation of the environmental baseline before any hydraulic fracturing and gas exploration or production takes place in the event that planning permission is granted. The investigations are independent of any monitoring carried out by the industry or the regulators, and information collected from the programme will be made freely available to the public.
