| Abstract: | Significant progresses have been made in recent years in precipitation data analyses at regional to global scales. This paper reviews and synthesizes recent advances in precipitation-bias corrections and applications in many countries and over the cold regions. The main objective of this review is to identify and examine gaps in regional and national precipitation-error analyses. This paper also discusses and recommends future research needs and directions. More effort and coordination are necessary in the determinations of precipitation biases on large regions across national borders. It is important to emphasize that bias corrections of precipitation measurements affect both water budget and energy balance calculations, particularly over the cold regions |
