Automated weather systems

The automated weather systems are being installed as a first step in testing the potential for flood prediction based on monitored conditions (Some illustrations and a full set of readings is shown in the next pages) The data is being updated to the website http:// http://www.tropicalclimate.org/digana_weather/index.htm

There is a link in the website to visit the forum (Sandaysoft) - Support forum for Cumulus weather station. It describes about various weather stations and its technical details. People communicate regarding weather station problems, new ideas, configurations of weather instruments.

Posting questions and getting answers and talks about climate.

Historical data (Out door Temp, Absolute-Relative Pressure,wind,direction,dew point,week-month-total rainfall) these recorded data’s are taken from weather instrument software starting from January 16th 2014 to April 30th 2014.
