Instrumentation and Technology Development

The ITD program aims to develop local instruments and technologies needed to sustain environmental monitoring and research in the country.

Most of the instrumentation currently being built are for atmospheric and climate monitoring, which include automated meteorological systems, and the detection of aerosols and gaseous pollutants.

Local technologies are likewise being developed for alternative energy and transport systems (in partnership with the Ateneo de Manila University), real-time webcasting of air quality and weather/climate information, and scientific visualization.

The program prioritizes the harnessing of local expertise and resources in the development of these devices for the scientific investigation and remediation of the environment.

Current projects under this program include:

Development of DOAS system to monitor criteria and toxic air pollutants
Optical PM monitor
Tunable diode laser detector for ambient methane
Scanning Mie LIDAR for aerosol profiling
Automated meteorological systems
Small-scale wind turbine systems
Hybrid transport systems
