WebThe Philippines contains many mountainous dynamical downscaling methods over the Philippines for islands and a sufficiently high-resolution representation of the April–June (AMJ) monsoon transition season, using mountains and coastlines is expected to be important in a high-quality 28-yr, 77-station daily rainfall dataset. Because the BCSD method does not explicitly adjust the trends (the slopes, in particular) in climate variables produced by GCMs, the monthly large-scale climate trends are extracted from the GCM temperature data. This is calculated as a 9-year running average for each individual month (e.g. the trend for all … See more While recent studies7,8 have shown that the choice of observational data can impact the final downscaled output, to maintain consistency between dataset versions, the latest … See more After all GCM values for a particular variable were bias-corrected, a spatial disaggregation was performed.
