Rain drop size distribution (DSD) was measured at four places in Southern India

{Thiruvananthapuram, Kochi, Munnar and Sriharikota (SHAR)} using a Joss-Waldvogel (JW) impact type disdrometer. The data for each minute were corrected for dead time errors and rain rate was computed from the corrected data. The data for a whole month were then sorted according to rain rate (R) into several classes ranging from 0.1 to >100 mm/h.

Recent clinical trials conducted by CESS in collaboration with the Regional Cancer Center, Trivandrum has shown that diffuse reflection spectroscopy (DRS) could turn out to be a highly sensitive tool to classify oral cavity tissues especially those of the tongue and lip that have poor classification sensitivities with laser-induced autofluorescence (LIAF). In this technique the DR ratio of oxygenated hemoglobin absorption

In India, Kerala state is known to have relatively high lightning incidence. The nature of spatial and temporal distribution of past incidents, type of thunderclouds which cause lightning, the topography, proximity to a mountain range and sea point to the possibility of the mountain weather aiding in Cumulonimbus cloud (Cb) formation. For investigating the role of mountain weather in convective Cb formation a field station consisting of an automatic weather station and a lightning detector was established

Centre for Earth Science Studies in collaboration with Indian National Centre for Ocean Information Services (INCOIS) under the Ministry of Earth Sciences (MoES), Government of India has recently installed first of two stations scheduled off Coastal waters of Kerala at 30m depth off Trivandrum. The coastal station will give real time data on coastal weather conditions which includes tide, current and wave parameters. This information is vital to the local community,

he Ocean State Forecast and Fishing Information System is jointly established by the Indian National Centre for Ocean Information System (INCOIS) and the Centre for Earth Science Studies (CESS). The information system issues real time details on tides, wind, waves, ocean current, etc for the use of the coastal community, Coast Guards, National Hydrographic Office etc.
