Several weather stations were installed in Negros, Panay, and other cane-producing provinces to generate environmental data. The weather stations measure and collect temperature, relative humidity, photosynthetic active radiation (PAR), and rainfall. The data are collected every hour, 24 hours a day. Components of the weather stations include:
1. Temperature sensor with measurement range of -20 degree Celsius to 70 degree Celsius and accuracy of +/- 0.6 degree Celsius;
2. Tipping bucket rain collector measures rainfall in 1/100 inch increment, self emptying, and meets WMO guidelines, accuracy of +/- 2%;
3. Quantum light sensor measures radiation between 400 to 700 nanometers (photosynthetically active range), measurement range 0 2500 umol/m/s, accuracy of +/- 5%;
4. Data logger has a capacity of 15,000 measurements stored in non-volatile memory.
The data are stored in a data logger and can be downloaded into a computer. Cane growers, planters associations, PAGASA, and various municipalities request weather data regularly.
The environmental data generated by the weather stations can be utilized to estimate crop maturity. Mathematical yield models can be derived from historical data (Yield and environmental data) and employed to make a more accurate crop yield estimate. The weather data can also be used by GIS to perform spatial analysis and generate thematic maps. The processed information from GIS could aid in policymaking at the national level.
