Paradise cannot be seen well from space because of cloud. In Oahu, for example, the average cloud cover is >60% and only one Landsat 8 (L8) satellite image has cloud cover of <10% since 2013. Cloud persists over the mountain ridges particularly.
HiMACC is an annual Cloud-free Composite (CC) image dataset created from L8 satellite imagery from 2013 to 2021. The CC image of any given year was created by merging the L8 top-of-atmosphere (TOA) reflectance images from that year and the two neighboring years.
HiMACC, as a multi-temporal dataset, is ideal for studying environmental changes related to processes such as urban expansion, agricultural abandonment, forest restoration, volcanic eruption, and land-climate interaction.
