OLYMPEX Scientists in the Field

OLYMPEX Scientists in the Field

From November 10 through December 21, NASA and university scientists are taking to the field to study wet winter weather near Seattle, Washington. With weather radars, weather balloons, specialized ground instruments, and NASA's DC-8 flying laboratory, the science team will be verifying rain and snowfall observations made by the Global Precipitation Measurement (GPM) satellite mission on a NASA-led field campaign, The Olympic Mountain Experiment, or OLYMPEX.


GCPEx Data Collection Summary and Example Observations

In total, 25 events were identified with two events classified as “clear air” flights conducted by the DC-8 to sample land surface emission characteristics.  Table 4 summarizes case date and time, event type, and airborne data collection during the field project.  Event total SWE amounts represent manual measurements taken by a Tretyakov gauge located inside a DFIR wind shield at CARE.  Precipitation types are characterized as rain (R), snow (S), or mixed precipitation that could include ice pellets (R/S).  Synoptic context/regime(s) were determined from the
