Advance Field Research Stations
Located in Himachal Pradesh, Uttarakhand and in Jammu & Kashmir.
Consists of three Walk-in Cold Chambers and three Portable Chambers for studies on snow mechanics and physics up to -40oC.Triaxial machine has also been developed indigenously for carrying out the experiments on snow and is working satisfactorily. State of the art equipment like Polycut microtome for serial sectioning has been installed. Centrifugal Tensile Testing Machine has also been developed to determine the tensile strength of low density snow.
Snow & Met Observatory
For collecting snow and meteorological data at various stations in J&K, Uttarakhand and Himachal Pradesh; recording weather, temperature, sunshine and seasonal snow cover; and studying synoptic situation leading to precipitation, snow distribution effects. Albedo studies are also conducted under simulated light.
Upper Air Stations
One Upper Air Stations has been established in HP and two in J&K.
Electronics and Instrumentation Centre
For regular maintenance of sensitive electronics systems and instruments in adverse climate conditions.
Data Receiving and Communication Centre
For collecting real-time data for research as well for identifying user-related problems.
Remote Sensing Laboratory
For identifying avalanche hazard areas, monitoring the condition and mapping of snow cover, planning control measures for various avalanche sites, snow characteristic evaluation, digital terrain modeling, GIS, etc
SASE has setup Luminescence dating lab with research focus mainly on Climate Change (Regional and Global), Glacier Dynamics, Spatio-temporal monitoring of Glaciers and landscape evolution.
Cold Concrete Lab
Cement based construction activities affects very much in snow bound regions during winter due to cold climate. Weather is termed as cold weather if the average daily outside temperature falls below 50C for three successive days. In addition to common operations of concreting i.e. mixing, transportation, placing, compaction, finishing, curing, it is required to given appropriate protection to concrete to prevent freezing of concrete till it gets minimum specified strength. Chemical admixtures in the form of accelerators, air entraining agents etc are used to give early strength to concrete and minimize the effects of freezing and thawing.
Cold weathering concrete study centre at HQ SASE Manali have all the basic facilities to carryout cold weather concrete studies. This laboratory is equipped with equipments such as cold storage chamber of size 2.4m x 1.4m x 1.40m having temperature range of -400C to +500C, 100 T automatic computer control compression testing machine, flexural testing machine, concrete core cutting & trimming machines, X-rays micro computerized thermograph and many other basic concrete technology equipments.
Structure Design Center
The Design center has facility of structural modeling, analysis and design software’s also the facility for the terrain analysis and DEM generation to study the functional requirement of Avalanche Control Structures. The centre is equipped with the facilities to simulate avalanche flow and snow drift phenomena.
Sensor Calibration Center
Snow and Avalanche Study Establishment has established a network of Automatic Weather Stations (AWS) in Himalayan region to collect various atmospheric and snow parameter data like temperature, humidity, albedo, wind speed and direction, snow depth, precipitation etc. using various sensors. This data is used at RDC Chandigarh to issue mountain weather and avalanche forecast. For proper working of the AWS and reliability of data regular calibration of various AWS sensors is necessary, hence a calibration lab is being set up at Mountain Meteorology Centre Jammu. Facilities for calibration of Temperature Sensors, Humidity Sensors, Wind Speed and Direction Sensors etc are being set up at this centre. The temperature and humidity sensor calibration facilities will be ready by the end of year 2011.

Cold Lab at Field Station at 3800m
There are two walk in cold chambers in Research Station Patseo (3800m), to carry out experiments on natural snow under controlled environmental conditions. Presence of different kind of snow layers in the snow pack needs to be investigated accordingly. The scientists are engaged to study the snow properties using different techniques/experimentation as follows:
a) Creep Experiments to study the snow settlement and development of Constitutive law for Snow.
b) Strain Rate experiment to develop the constitutive law for snow and determine strength properties in different state of stress.
c) Fracture Toughness experiments on different homogeneous snow and different snow interfaces.
d) Snow Characterization using Ultrasonic spectroscopy.
e) Acoustic Emission based monitoring and analysis of snow deformation and micro failure activity.
f) Air permeability experiments.
g) Experiments on melt water Percolation.
h) Experiments to find out Irreducible water saturation for different snow layers.
i) Experiments on Thermal conductivity and diffusivity of snow.
j) SMP profiles of different natural snow layers for layer structure identification.
