One example is the Cloudnet (6) data product, which combines observations of a cloud radar, a microwave radiometer, and a
ceilometer (Illingworth et al.
This technology was replaced by the rotating beam M
ceilometer, which in turn was phased out around 1990 and replaced with the laser beam
ceilometer, which is widely used today.
It protects the
ceilometer's inner life against even the harshest weather conditions.
The other
ceilometer used is the Vaisala CL51, which uses a 910 [+ or -] 10 nm diode with a pulse frequency of 6.5 kHz as an optical source.

* The remote miniature weather station and companion laser
ceilometer, a small, autonomous weather station capable of recording, storing, and reporting meteoric data for SOF aircrews.
The
ceilometer is designed to produce accurate imagery in varied weather conditions including fog cover and torrential downpours.
The observational strategy relied on an intensive distributed network of 49 active meteorological towers (masts), 18 scanning and 8 profiling Udars, 1 water vapor differential absorption lidar (DIAL), 1 profiling radar, 1 profiling radar radio acoustic sounding system (RASS), 2 profiling sodar RASS, 2 radiosonde launch sites, 2 microwave radiometers (MWR), 2 tethered lifting systems (TLS), 1 scintillometer, 1
ceilometer, 9 acoustic sensors (microphones), 3 seismometers, 4 high-resolution microbarometers, and an aerosol particle-sizing instrument.
Pilot balloons were used by observers as far back as WWII, but the electronics revolution of the 1950s drove federal agencies to develop the rotating beam
ceilometer (RBC).
Attributing to the application of sky imagers and
ceilometer, automatic observation has been realized in cloud cover and cloud base height [6].
Fellbach, Germany, May 23, 2015 --(PR.com)-- Lufft left no stone unturned, to fulfill all requirements of the recent
ceilometer tender of the Dutch royal weather service KNMI.
- OpenStack - enhancements include agent-free discovery and analysis of OpenStack Image Service (Glance) images; inventory and reporting for OpenStack Block Storage (Cinder) and OpenStack Object Store (Swift); integration with OpenStack Identity (Keystone) for service discovery and multi-tenancy; enhanced event and alert handling with RabbitMQ and QPID support; capture of additional performance metrics from OpenStack Telemetry (
Ceilometer); configuration drift; tracking analysis; policy and governance.
