Estimation of missing rainfall data in northeast region of Thailand using spatial interpolation methods [PDF]

open access: yes, 2011
Ground-based rainfall observations are the primary sources of precipitation data used in most developing countries. However, those observations are frequently damaged or incomplete, thus missing data is always a problem.
