Cloud cover fraction

WebClouds cover about 70% of the earth's surface. They are important components of the cliimate's water and energy budgets. Historically, cloud reports have come from station or ship observations. WebWe find that at a grid resolution of 625 km 2 (commensurate with a 0.25 ∘ grid size at the tropics), cloud detection uncertainties are positively correlated with cloud-cover fraction in the cell and are larger during the day than at night. Daytime cloud detection uncertainties range between 2.5 K for clear-sky fractions of 10–20% and 1.03 K ...
