Satellites within the current precipitation constellation are old, with many missions beyond their designed operational lifetime. It is therefore crucial that there is a concerted program of new satellites and sensors to ensure continuity in satellite-based precipitation measurements. Planning the future constellation of precipitation sensors should include a long-term strategy for sensors that meet scientific and user requirements, support for current missions beyond their normal lifetime, new technology such as cubesats, and, fundamentally, a commitment to and support for current and planned precipitation-capable missions. Issues and considerations in designing this next generation of precipitation sensors are discussed in this subchapter, which also includes a concise inventory of missions planned for launch over the next decade.
