Level 2 AIA 19.3nm images (calibrated and corrected for degradation) are used, at a cadence of one AIA image every 6 hours. Only coronal holes older than three days are being reported. Bounding box and characteristics such as areas and pixel intensity statistics, on AIA 19.3nm and HMI magnetogram images are provided.rob_spoca_ch.datalinkSPoCA coronal holes datalinkgranule_uidThe granule_uid of the detectionmeta.idcharindexedprimarythumbnail_urlURL of a thumbnail imagemeta.ref.urlcharnullablech_stat_aia_image_urlURL of the AIA image onto which the coronal hole statistics are computedmeta.ref.urlcharnullablech_stat_hmi_image_urlURL of the HMI image onto which the coronal hole statistics are computedmeta.ref.urlcharnullableprovenance_urlURL of the provenance file for the coronal hole mapmeta.ref.urlcharnullable
