This dataset collection contains datasets of 5 day back trajectories have been computed on a routine basis using analyses from the European Centre for Medium Range Weather Forecasting (ECMWF). The three components of the wind and surface pressure over three launch grids covering the UK, the mid-Atlantic storm track region and the eastern USA, plus back trajectories from field campaign instrument sites were used to output datasets consisting of latitude, longitude and pressure of the trajectory every 30 minutes.

CASIX, the Centre for observation of Air-Sea Interactions & fluXes, is a NERC Centre of Excellence in Earth Observation. The scientific focus was on advancing the science of air-sea interactions and reducing the errors in the prediction of climate change. The primary goal was to quantify accurately the global air-sea fluxes of carbon dioxide (CO2). CASIX accelerated the exploitation of new Earth Observation satellite data to further the understanding of marine biogeochemistry in the Earth System. CASIX links NERC Centres, university groups and the Met Office to model ocean circulation and the ocean carbon cycle. This dataset collection contains global monthly primary production estimates derived using the Smyth et al 2005 model from SeaWiFS data.

This dataset contains ECMWF trajectories model forecast data for 1996.

Tropospheric ORganic CHemistry Experiment (TORCH) was a Natural Environment Research Council (NERC) Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00145. Duration 2002 - 2005) led by A. Lewis, University of York. TORCH 1 took place in July and August 2003 at Writtle College, near Chelmsford, Essex. This dataset contains model outputs.

This dataset contains WACCM-X model results under RCP8.5 (Representative Concentration Pathway) carbon dioxide increases and high solar activity (F10.7 = 200 sfu). These cover ground level to a pressure level of 4e-10 hPa (~300 km altitude) on a global 144x96 longitude-latitude grid . Data is given in daily instantaneous (.h2.) and monthly average (.h0.) files in the netCDF format. Default WACCM-X outputs remain, along with the following additional variables: 'PS' - Surface Pressure 'Z3' - Geopotential Height (above sea level) 'T' - Temperature 'U' - Zonal Wind 'V' - Meridional Wind 'CO2' - Carbon Dioxide Concentration 'CO' - Carbon Monoxide Concentration 'NO' - Nitric Oxide Concentration 'H2O' - Water Vapour Concentration 'O' - Atomic Oxygen Concentration More detail on each variable is given within the netCDF files and the readme file. 64 month runs from edited initial files at 10 year intervals from 2015 to 2095 under RCP8.5. There is also a 28 month 1975 run and 64 month 2000 run. All of these cyclically repeat the initial year. These are separated into individual folders with the RCP8.5 CO2 concentration listed. The first 4 months of each of these datasets have been ignored in processing as the model spins up, but are included here for completeness. This data was collected to understand the density drop at low earth orbit altitudes as carbon dioxide concentrations increase.
