E21. Agro-meteo weather stationsAgro-meteorological weather stations in Timor-Leste

The department of Agriculture, Land, Geographic Information Systems and Agro-meteorology (ALGIS) measures the weather at 44 weather stations across all Agro-Ecological Zones (AEZs) in Timor-Leste. The stations sample climatic conditions including rainfall, temperature, relative humidity, solar radiation wind speed, gust speed, wind direction, soil temperature (surface and 5cm depth) and soil moisture (10 cm depth). Samples are taken every 3 minutes and the data is logged every 15 minutes. The system is comprised of 15 stations in the Primary Network (which include wind direction and soil sensors) and 29 stations in the Secondary Network.  Long term weather data records are used for crop research and improving resilience to climate extremes such as flooding, drought and high winds. Weather data is fundamental in designing infrastructure such as storm water drains, buildings and bridges. Other applications include disaster risk management and early warning systems. Primary Network stations are equipped with automatic data transfer systems with alerts that set to notify the Government of extreme weather events.
