Trade wind clouds are often organized on the mesoscale (O(100 km)), forming different cloud patterns. We present C³ONTEXT (a Common Consensus on Convective OrgaNizaTion during the EUREC⁴A eXperimenT), a dataset that contains information about the mesoscale cloud patterns identified during the EUREC⁴A (Elucidating the role of clouds–circulation coupling in climate) field campaign in January–February 2020 and thereby provide the mesoscale context for the campaign's measurements.
