(1) Altitude profiling of meteorological variables using balloon-borne Sondes.

(2) Eddy Covariance System for measurement of surface energy fluxes and fluxes of water vapour and CO2

(3) Doppler SODAR

SODAR is an acronym for SOund Detection And Ranging. The echograms obtained from SODAR represent the state and vertical extent of the turbulence in lower atmosphere. SODAR has been used to study the rate of dissipation of turbulent kinetic energy, horizontal and vertical wind variances, momentum flux and mesoscale studies of sea breeze and associated phenomena.
 


(4) Ground-based Disdrometer

Disdrometer is a powerful ground based instrument used for classification of precipitation and to measure Drop Size Distribution (DSD). From DWD, one can measure rain rate, reflectivity factor and liquid water content at the ground continuously and automatically.
 


(5) Micro-rain Radar

The Micro Rain Radar (MRR) a highly resolution radar operates at a frequency of 24 GHz installed at Thumba under Ka band propagation experiment is used extensively to characterize the tropical rain. This radar measurement of rain was obtained with fine spatial and temporal resolutions like one minute time resolution and 200 m height resolution.
 


(6) Fast response Sonic Anemometer measurements of 3-dimensional winds and virtual potential temperature for studying surface layer turbulence


 



(7) Surface layer meteorological measurements onboard Oceanic Research Vessels

During different ship-borne field experiments, such as INDOEX (Indian Ocean Experiment), BOBMEX (Bay of Bengal Monsoon Experiment) and ICARB (Integrated Campaign for Aerosols gases and Radiation Budget) different meteorological sensors are mounted onboard Oceanic Research Vessel on a long retractable boom close to the ship bow at two levels above the sea surface. Surface layer meteorological measurements obtained during such cruises are used for determination of air-sea interface fluxes over the different oceanic regions.
 


(8) Modular Weather Station (Mobile Meteorological Tower)

This is one of the latest inclusions in BLPAM experimental facility. It is quite a portable instrument particularly taken for campaign mode observations of surface layer meteorological features such as air temperature, relative humidity, wind speed, wind direction, atmospheric pressure and rainfall. The instrument is connected through a laptop/computer and can run on solar batteries provided with the setup.
 


(9) Surface radiation measurements (shortwave and longwave) for energy budget studies
