Introduction to Missing Data

Availability and acquisition of chronologically continuous, accurate, and gap-free hydrometeorological and climatic data are critical for modeling and studies that aid natural resources management and disaster mitigation tasks. Climatological data are generally considered to be observations of climatic conditions obtained from various instruments in space and time. Meteorological data mainly consists of parameters such as precipitation, temperature, dew point, humidity, wind speed and direction, solar radiation, and several others using a network of monitoring sites.
