Weather forecast

These pyranometers installed at the Manila Observatory on the Ateneo de Manila University campus in Quezon City are used to measure actual solar radiation for comparison with forecast projections. Ateneo researchers improved WRF-solar forecasts by applying a mathematical algorithm called a Kalman Filter (KF). Using data from various Metro Manila weather stations, they found that under some conditions they could minimize the discrepancy between forecasts and actual observations.
