Laser Precipitation Monitor (LPM) with a wind sensor is an advanced instrument that is used to measure and monitor precipitation. It works on the principle of laser scattering, which is used to detect the presence of precipitation particles in the atmosphere. The wind sensor measures the speed and direction of the wind, which is necessary for the accurate measurement of precipitation.
It provides high-resolution measurements of precipitation, including the size, shape, and velocity of individual particles which is useful in understanding the physical processes that govern precipitation, and in predicting the impact of precipitation on the environment.
The LPM with wind sensor has many applications in research. It is used to study the microphysical properties of precipitation particles, such as their size distribution and shape. It is also used to measure the spatial and temporal variability of precipitation, which is important for understanding the hydrological cycle and its impact on the environment. Additionally, the LPM can be used for weather forecasting, flood monitoring, and climate research.

Ceilometer is a remote sensing instrument used for measuring the height and extent of clouds and aerosols in the atmosphere. It operates using the principle of light detection and ranging (LIDAR), which involves emitting pulses of laser light and measuring the time it takes for the light to reflect back from atmospheric particles.
Ceilometers are commonly used in atmospheric research for a variety of applications, including:
Cloud and aerosol profiling: Provide information on the vertical distribution of clouds and aerosols in the atmosphere.
Boundary layer studies: Used to measure the height of the atmospheric boundary layer.
Weather forecasting: Provide real-time information on cloud and aerosol properties, which can be used to improve weather forecasting models.
Current Status: Active
Electric Field Monitor is a remote sensing instrument that is commonly used in atmospheric research to measure the electric field strength and polarity in the atmosphere. The principle of operation of the Electric Field Monitor is based on the measurement of the voltage induced by the atmospheric electric field on a pair of electrodes.
A lightning sensor is a device that is used to detect lightning strikes. These sensors work by detecting the electromagnetic radiation that is emitted by a lightning bolt. When a lightning bolt occurs, it generates a wide range of electromagnetic radiation, including radio waves, microwaves, and even X-rays.
