APCADA is a real-time system developed for estimating the actual sky cloud cover with surface measurements of longwave downward radiation, temperature and relative humidity every 10 minutes 24 hours a day.

Note: Thin high clouds (cirrus clouds) cannot be detected by APCADA. Thus, only total cloud amount without cirrus clouds (called partial cloud amount) is estimated by APCADA.
