| Resource Title | Assessing the Impact of Climate Change on Solar Resource in the Philippines Using MODIS and In-Situ Measurement |
| Date Issued | 18 December 2026 |
| Abstract | Solar radiation (SR) drives the climate on Earth; however, it could be impacted by climate change. The global circulation model (GCM) uses mathematical equations to model the effect of climate change. In the Philippines, there were climate change assessments for rainfall and temperature but assessment for SR is not yet available. This study aims to evaluate the impact of climate change on SR through statistical downscaling of small- and large-scale variables. The Moderate Resolution Imaging Spectroradiometer (MODIS)-derived SR (DSR) and in-situ weather measurements are used as small-scale variables, and the baseline and future projections from GCM are used as large-scale variables. Climate change projections show an increase in SR ranging from 120 W/m²/day to 224 W/m²/day in the remaining years of the 21st century. In particular, the sites with the lowest and highest daily average increase were the cities of Dagupan and Davao, respectively. Dagupan has an increase of 120 W/m²/day at emission scenario of shared socio-economic pathway (SSP) 2-4.5 mid-future and Davao City has an increase of 224 W/m²/day at SSP2-4.5 mid-future. Places closer to the equator show a greater increase, than those farther away. The small-scale variables drive the future projection; high SR values of MODIS DSR correspond to high projected SR. Other weather factors such as rainfall were also examined. Davao City has the highest decrease in projected rainfall at -3.60 mm/day SSP2-4.5 mid-future and highest increase in projected SR at 224 W/m²/day SSP2-4.5 mid-future. Therefore, future rainfall projections show an inverse relationship with SR projections; a decrease in rainfall corresponds to an increase in SR. The increase of SR in the future has both positive and negative impacts in various sectors. In agriculture, it promotes crop yield. In energy, specifically renewable energy, the increase in the future of SR is favorable to the Philippines’ Department of Energy’s (DOE) targ |
