This dataset contains cloud images from the NCAS Camera 11, one of two identical cameras (designated as ncas-cam-11 and ncas-cam-12) captured at various sites around the Magdalena Mountains, New Mexico, USA, as part of the Deep Convective Microphysics Experiment (DCMEX). DCMEX examined the formation and development of clouds over mountains during July and August 2022. These cameras were designed to take simultaneous images of the same object while placed a distance apart to create a stereo image, but this was not always possible; on some days only one camera was used or the two cameras were deployed in separate locations. The images from this camera were taken during the duration of the DCMEX campaign of clouds from a range of sites. These are accompanied by similar images from a sibling camera (see connected dataset). Where the two cameras were operated at the same site they were synchronised in terms of camera settings (exposure, etc) and camera pointing directions to facilitate the onward use of images as stereoscopic imagery. For those latter instances files have been marked with stereo-a or stereo-b within the filename to denote where the images form the left of right image for such images. Other images do not contain these additional filename fields to denote when the cameras were used in stand-along mode. Note, due to the nature of coordinating images between the two cameras one was designated as the primary camera from which the settings were then conveyed to the secondary camera by the coordinating software. As a result exact image synchronisation wasn't possible and thus the secondary camera image may have a timestamp that is a second or so later.

This dataset contains O3 and NOx measurements made at the BT tower, London (T35 level), sampled from a height of approx 180 metres above the ground. The measurements were made using a TEI 49i analyser and TEI 42CTL analyser. This dataset is part of longterm measurements at the BT tower for the National Centre for Atmospheric Science (NCAS)

This dataset contains scan data from the National Centre for Atmospheric Science Atmospheric Measurement and Observation Facility's mobile X-band radar during the Radar Applications in Northern England (RAIN-E) project. The radar collected data at Sandwith, near Whitehaven in Cumbria from October 2018 to December 2020.

This dataset contains scan data from the National Centre for Atmospheric Science Atmospheric Measuring Facility's mobile X-band radar between 1st November 2016 to 4th June 2018 at Chilbolton Facility for Atmospheric and Radio Research (CFARR), UK, as part of ongoing long-term observations made by the NERC National Centre for Atmospheric Science (NCAS). The radar transmits pulses of electromagnetic radiation and measures the amount of energy backscattered to the receiver from which the location and intensity of precipitation, radial winds and polarisation parameters can be calculated. Parameters available in these data files include: dBZ - equivalent reflectivity factor; V - radial velocity; W - spectral width; ZDR - differential reflectivity; KDP - specific differential phase shift; PhiDP - differential phase shift; RhoHV - co-polar cross correlation coefficient; SQI - signal quality index or normalized_coherent_power. A complete list of all available parameters is available on the CEDA data catalogue record for this dataset. The sur files contain a volume of scans at different elevation angles between 0 and 90 degrees, approximately every 5-6 minutes. The rhi files contain a single cross-section scan at a given azimuth and an elevation range of 0 to 180 degrees, every 5-6 minutes. The data are available as netCDF files to all registered CEDA users under the Open Government License.
