Where the cloud record comes from
NASA POWER records the night-time cloud amount over every place on Earth, on a grid of about 50 km. For each place the site averages 2014 to 2023 by month, so the numbers describe a typical year, not a forecast. Places in the far north with midnight sun have no cloud record for those months, which count as zero clear nights here. Coastal grid cells mix sea and land, so a place on the shore can read cloudier or clearer than the town itself.
