Continuous and reliable global precipitation information is crucial for myriad of weather, climate and hydrological applications. The importance of precipitation in the form of rain, hail, sleet, snow etc. is known to science and clear to a layman. However, it’s quite tricky to measure past precipitation trends or predicting accurate future forecasts. There are three main categories of precipitation data sets available: ground based, satellite-based and blended products of ground and space data (Climate Data Guide, 2014).

About 40% of the World’s population lives within 100 km of the coast (United Nations 2017).  Sea levels are on the rise around the World and the trend is accelerating every year. The UN, countless international organizations and national agencies are working hard every year to support the efforts of climate scientists to accurately model our changing climate. The role of ice in shaping the Earth’s seas is indisputable. As continental ice melts and as ice sheets break off from continental shelves and fall into the sea, more and more coastal communities are threatened.

Environ 40 % de la population mondiale vit à moins de cent kilomètres des côtes (Nations unies, 2017).  Le niveau des mers est en hausse dans le monde entier et la tendance s'accélère chaque année. L'ONU, d'innombrables organisations internationales et des agences nationales travaillent ardemment chaque année pour soutenir les efforts des climatologues afin de modéliser avec précision notre climat changeant. Le rôle de la glace dans le modelage des mers de la Terre est indiscutable.
