GISMOS Gathers Detailed Pre-storm Data

Track GISMOS (GNSS [Global Navigation Satellite System] Instrument System for Multistatic and Occultation Sensing) as it gathers onshore moisture feeding data (for the 3-4 days of heavy rain forecasted in Northern California). GISMOS is gathering data from its perch aboard the NOAA G-IV aircraft during the NOAA CALWATER2015 Atmospheric Rivers campaign. Go to and select the NOAA GIV (N49F) on the dropdown list.

GISMOS was created by IGPP geophysicist Jennifer Haase and her colleagues—and funded by a NSF Rapid grant—to capture detailed weather conditions with precision to improve storm predition and modeling. For more information, please visit:
