It covers airfield support, mission services, resource protection, weather watches, TAF support, and space weather impacts. It requires specified backup, observation, encoding, dissemination, and continuous meteorological watch procedures.
Back-up is the process of manually editing/adding data or dissemination capability when the primary method is not operational, unavailable or suspected to be providing erroneous data (e.g. sensor/comm. failure, dew point higher than temperature).
Back-up is required during controlled airfield hours and may be required during uncontrolled airfield hours when elements triggering weather warnings are erroneously reported and/or when required for supplementation criteria above; otherwise, there is no requirement to back-up the system/sensor outside controlled airfield hours.
A Kestrel will be used to take observations while performing back-up procedures.
TAFs are issued at 0400, 1200 and 2000 Zulu time. (paragraph 15-111)
The 25 OWS and March WF conduct a continuous meteorological watch to identify and assess emerging and imminent threats to March ARB. (paragraph 15-111)
