  • Data from observations made at the Cape Verde Atmospheric Observatory (CVAO) which exists to advance understanding of climatically significant interactions between the atmosphere and ocean and to provide a regional focal point and long-term data. The observatory is based on Calhau Island of São Vicente, Cape Verde at 16.848N, 24.871W, in the tropical Eastern North Atlantic Ocean, a region which is data poor but plays a key role in atmosphere-ocean interactions of climate-related and biogeochemical parameters including greenhouse gases. It is an open-ocean site that is representative of a region likely to be sensitive to future climate change, and is minimally influenced by local effects and intermittent continental pollution. Since November 2011, real-time N2O (Nitrous Oxide) and CO (Carbon Monoxide) concentrations have been simultaneously and continuously measured using an Off-Axis Integrated-Cavity Output Spectroscopy (OA-ICOS) analyser (Los Gatos Inc). In November 2012, a Greenhouse Gas Analyser (GGA) using the same fundamental measuring technique was added and placed in series to measure CO2 (Carbon Dioxide) and CH4 (Methane) concentrations. Both devices are configured to sample at a frequency of 1Hz and both have the precision and accuracy to conform to measurement recommendations as defined by Global Atmosphere Watch (GAW). The dataset contains hourly measurements of CO, CO2, N2O and CH4. Data were collected by collaboration between the University of Exeter and the Max Planck Institute for Biogeochemistry.

  • Meteorological data was collected by the University of Manchester at Langmuir ground station in the Magdalena Mountains, New Mexico, between July and August 2022 as part of the Deep Convective Microphysics Experiment (DCMEX) project. This dataset contains meteorological data from two ground meteorological stations. A Gill MaxiMet GMX600 meteorological station was installed at the Langmuir Laboratory main building (33.97495N, 107.18100W, ~3255 m) next to the Digitel aerosol filter sampler and provides measurements of wind speed, wind direction, temperature, humidity, pressure, and precipitation rate. A second meteorological station, a Vaisalla WTX536 meteorological station, was installed at the Langmuir Kiva-2 laboratory next to the Digitel aerosol filter sampler and provides measurements of wind speed, wind direction, temperature, humidity, pressure, and precipitation rate. The meteorological stations are supported by the University of Manchester scientists.

  • Data were collected under the NERC funded project - The role of land-use change on influencing mountain climate on Kilimanjaro, East Africa (NE/J013366/1) - lead by Dr Nicholas Pepin (University of Portsmouth) which investigated the influence of land-use on surface climate (temperature and moisture availability) on Mount Kilimanjaro in Africa. Relative humidity measurements were taken at hourly intervals at 23 stations on Mount Kilimanjaro between September 2012 and September 2015. Specific station locations (elevation and lat/long) are stated in the data and are ordered in a transect across the mountain from South-West over the top to North-East. Two of the stations have both ground level and air level sensors (hence there are 25 readings not 23). Additional information about station locations and missing data can be found in a PDF on the CEDA archive.
