Description
AERONET sites using a DCP satellite transmitter send scheduled status messages at regular intervals throughout the day. When AERONET stops receiving those messages, the transmitter may have lost power, lost line of sight to the satellite, or developed a hardware fault.
Condition(s)
DCP messages are scanned for each satellite during the last 15 days; if the last three or more continuous days have missed instrument data and they have not been restored, then the date of last received instrument data is determined
