Collecting and Bias Correcting Observed Climate Data

In the Indonesian case study, TRMM data (1998–2011) was merged with APHRODITE data (1981–2011) to extend the time span of available data. However, the APHRODITE data tended to have a negative bias (i.e. underestimate) for rainfall compared with the TRMM data. To reduce this bias, APHRODITE data was corrected using quantile-based bias correction.
