Short summary of the project (2,000 characters max)

This research examines the impacts of two scenarios of solar geoengineering (e.g. G4 and NCAR-GLENS) on extreme temperature and precipitation change over Indonesia as one of tropical regions. These two scenarios carried out experiments following the RCP4.5 (for G4) and RCP8.5 (for GLENS) pathways as the baseline/control simulations. The study will be focused on investigating the difference of extreme temperature and precipitation change generated by the scenarios and the significant change over time as well as to examine the level of agreement of each experiment to project the extreme temperature and precipitation change over specific climate zones in Indonesia. The extreme temperature and precipitation is represented by 8 extreme climate indices following the definition of the Expert Team on Climate Change Detection and Indices (ETCCDI) i.e. R10mm, SDII, Rx5day, R95pTOT, CDD for precipitation and TXx, TNn, and WSDI for temperature extreme.

 This research is very important to be carried out due to the fact that Solar Radiation Management (SRM) is a new field in Indonesia and no research has been conducted to study the SRM Impact over Indonesia. The research team consists of qualified young scientists with strong background in climate modelling and statistical analysis. The Principal Investigator (Dr. Heri Kuswanto) has strong experiences to working on climate change related projects in Indonesia, in particular of extreme weather and climate events. He has been working with the Agency for Meteorology, Climatology and Geophysics (BMKG) Indonesia for regional climate modelling. This research involves one scientist from BMKG Jakarta who is expert on Indonesian climate analysis and climate modelling.
