  • The NPOL instrument, a large radar dish attached to a trailer under a blue sky
    The Midlatitude Continental Convective Clouds Experiment (MC3E) took place from April 22 – June 6, 2011, near Lamont, Oklahoma in the region surrounding the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Program Southern Great Plains Central Facility. The experiment was a collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and the NASA's Global Precipitation Measurement (GPM) mission Ground Validation (GV) program.
  • Tornado funnel
    In late April, 2011, a giant storm system covered a large portion of the central and southeastern United States, causing the largest outbreak of tornados since 1974. One month later on May 22, another EF-5 tornado flattened Joplin, Missouri, killing 141 people and injuring hundreds of others. The TRMM satellite saw the severe weather unfold over the United States during both the April outbreak and the Joplin tornado.
  • CG image of the GPM satellite as it passes through space.
    The GPM Core Observatory, scheduled for launch in 2014, will provide advanced information on rain and snow characteristics and detailed 3-D views of precipitation structure, which help scientists study and understand Earth's water cycle, weather, and climate. Carrying both a dual-frequency radar and a multi-channel microwave radiometer, the Core Spacecraft will provide a new reference standard for precipitation measurements from space.
  • Visualization of a Tropical Cyclone from above as it approaches Florida
    Every year tropical cyclones (hurricanes and typhoons) cause considerable loss of life and property around the world. Constantly scanning the Earth’s surface, the TRMM instruments allow scientists to track tropical cyclones and forecast their progression. GPM will extend cyclone tracking and forecasting capabilities into the middle and high latitudes, providing new insight into how and why some tropical cyclones intensify as they move poleward.
