Overview The Iowa Flood Studies (IFloodS) are a ground measurement campaign taking place in eastern Iowa from May 1 to June 15, 2013. The goals of the campaign are to collect detailed measurements of precipitation at the Earth's surface using ground instruments and advanced weather radars and, simultaneously, collect data from satellites passing overhead. The ground instruments will characterize precipitation -- the size and shape of raindrops, the physics of ice and liquid particles throughout the cloud and below as it falls, temperature, air moisture, and distribution of different size

International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic Winter Games (ICE-POP 2018) ICE-POP 2018 takes place during the Winter Olympics (February-March) of 2018 and focuses on the measurement, physics, and improved prediction of heavy orographic snow in the PyeongChang region of South Korea. ICE-POP is led by the Korean Meteorological Administration (KMA) as a component of the World Meteorological Organization’s (WMO) World Weather Research Program (WWRP) Research and Development and Forecast Demonstration Projects (RDP/FDP). The 23rd Olympic Winter and the 13th

Ground Validation observations for statistical validation of GPM products are made in a series of investigator-led field measurement campaigns, known as Extended Observation Periods (EOPs). EOPs last several months and are punctuated by one or more Intensive Observation Periods (IOPs).

Looking ahead it is becoming apparent that the future of precipitation research is probably not one in which satellite data are used in isolation. Instead, integration of satellite precipitation measurements with ground observations, cloud resolving model s (CRMs) and land surface data assimilation systems (LDAS) is likely to replace satellite-only precipitation products, particularly for forecasting and hydrological applications that require precipitation as input. This is already apparent in the analyzed precipitation products over the continental US and similar activities in Japan. Hence
