    "abstract": "The validation of NASA Global Precipitation Mission (GPM) satellite\nprecipitation products is important for their credibility and utility within\nthe larger community. This document defines GPM ground validation scientific\nobjectives and several programmatic components for meeting those objectives.\nMulti-year, multi-sensor ground-based observation programs in a few locations\nare proposed to generate local observation products and global error covariance\nproducts. Focused measurement programs utilizing aircraft, ships, and\nground-based measurements would fill in geographic and scientific gaps not\naddressed by the multi-year observing programs.",
