Definition of ceilometer in US English: ceilometernounsēˈlämədərsēˈlämədər A device for measuring and recording the height of clouds. Example sentencesExamples - Our ceilometer observations of large numbers of birds near crests of ridges are particularly relevant in that regard.
- Changes in diurnal census data were associated with specific patterns of nocturnal migratory behavior observed by radar and ceilometer.
- Arrivals and departures of birds inferred from our diurnal visual census were clearly related to nocturnal flight behavior as observed with ceilometers and radar.
- The distribution of all track directions observed with radar and ceilometers for all sites was bimodal with similar numbers of birds moving southsoutheast and southwest.
- The combination of high-resolution radar, ceilometers, and daily ground counts at multiple sites provided a view of autumnal migration through complex topography at a resolution not previously attained in North America.
- Radar and ceilometers revealed large numbers of migrants passing through our study area.
- We made simultaneous observations with ceilometer and radar for one hour on all 30 nights with suitable weather from 28 August to 10 October 1992, starting one hour after civil sunset.
- The lasers are also built into laser ceilometers that measure cloud height.
- Numbers of birds detected with radar and ceilometers were highly correlated with each other, but were not significantly correlated with numbers of birds netted the next morning.
- Direction and density of nocturnal migrants detected with radar and ceilometers were compared with changes in species counts from daily censuses.
