Abstract
Cloud camera images taken during the Wessex convection (WesCon) experiment - Observing the Evolving Structures of Turbulence (WOEST) campaign during the summer of 2023. This camera layout consists of three pairs of perspective cameras, arranged in a triangle and intersecting over the Chilbolton Atmospheric Observatory, along with a pair of all-sky cameras at Chilbolton.
The ARray of Ground-based Upwards-pointing Sensors (ARGUS) cameras were deployed over June and July 2023 and were operational until the end of September 2023. The cameras were scheduled to take images every 5 seconds. These images have been compressed to mp4 files to make them easier to retrieve over the 4G network during the observation period. Each file lasts one hour. Nighttime calibration images (of the star field) are provided for each camera.
The cameras were run using code available under doi: 10.5281/zenodo.10795301

Access to these data is available to any registered CEDA user. Please Login or Register for a CEDA account to gain access.
Use of these data is covered by the following licence(s): http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
Data uploaded as created by the cameras. Truncated files (due to power issues) have been repaired using known-good file headers. Data were prepared by the project team before archiving at CEDA. |
| Data Quality: |
Data was collected for all periods where the cameras were operating, with some gaps due to a lack of solar power. In addition, near the start of the observation period, water ingress means that some images are blurred until the cameras were replaced. Additional notes are provided in the operation calendar.
Note that cameras may occasionally drop frames. Following the identification of this issue on July 20th, the images are timestamped in the upper left corner.
