Handheld cloud altimeter

1.Product introduction of Handheld cloud altimeter

Handheld cloud altimeter is a handheld smart device that monitors cloud base height, cloud layer thickness, and solid target distance, and displays the measurement results in real time. It can be used for manual single measurement or automatic continuous operation.

2. Application fields of Handheld cloud altimeter

This equipment can be widely used in cloud observation and research, aviation and navigation meteorological support, military meteorological support, silhouette rocket rain enhancement operations, etc.

3. Working principle of Handheld cloud altimeter

The equipment is based on the principle of laser ranging. The laser transmitter emits periodic laser pulses into the atmosphere. The laser receiver receives the backscattered signals from clouds and the atmosphere. The processor collects and processes the received signals. After inversion calculations, each component is obtained. The extinction coefficient of the height atmosphere is used to determine the cloud layer and calculate the cloud base height value.

4. Functional features of Handheld cloud altimeter

The device can measure cloud base height or solid target distance either vertically or tilted. It is small in size, light in weight, not limited by station space conditions, and is flexible in measurement and use. The device has a built-in lithium battery, and the observation data can be displayed on the LCD screen in real time and stored inside the device for easy reading and analysis in the future. The ergonomic design allows for temporary hand-held observation, or it can be mounted on a tripod for long-term continuous observation.
