OLYMPEX Scientists in the Field

OLYMPEX Scientists in the Field
Friday, December 11, 2015
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. Rachael Kroodsma is the instrument scientist for the CoSMIR on board NASA's DC-8 airborne laboratory as part of the OLYMPEX field...

The Olympic Mountain Experiment, or OLYMPEX, is a NASA-led field campaign, which will take place on the Olympic Peninsula of Washington State from November 2015 through February 2016. The goal of the campaign is to collect detailed atmospheric measurements that will be used to evaluate how well rain-observing satellites measure rainfall and snowfall from space.

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. Credits: NASA's Goddard Space Flight Center The Pacific Northwest was chosen because of its frequent and persistent winter rain and snowfall. On average 100 to 180 inches of precipitation fall a year, making it one of...

NASA to Host OLYMPEX Media Day

Media are invited to go behind the scenes of a comprehensive field campaign focused on yielding new insights into global precipitation at a special event on Nov. 11, 2015. NASA's DC-8 deploys to Iceland on a mission to study Arctic polar winds. NASA's DC-8 flying laboratory will be featured as part of a special media event on Nov. 11, 2015 focused on the Olympic Mountain Experiment (OLYMPEX), an Earth science campaign aimed at validating Global Precipitation Measurement.

Six Week GCPEx Campaign Concludes

February 29 marked the last day of the GPM Cold Season Experiment. After six weeks of no snow, light snow, rain, and some nice heavy snowstorms, the GCPEx team is heading home.

They captured a wide array of different types of snow and rain from Eastern New York as the DC-8 flew in from Maine to north of the CARE site in Huronia and Georgian Bay, off of Lake Huron

Saving the Best for Last - Prelude to a Storm

DC-8 Cockpit
Joe Munchak is a scientist at Goddard Space Flight Center who specializes in remote sensing of snow. This week he writes from the air in the DC-8 out of Bangor, Maine. Last time I wrote for the GCPEx blog, I was stationed in Barrie, Ontario with the ground team. I’ve since switched hats to that of CoSMIR Instrument Scientist. CoSMIR (Conically Scanning Millimeter Imaging Radiometer) is one of two instruments on the NASA DC-8 which is based out of Bangor, Maine – my home for the past ten days. With CoSMIR and the Airborne Precipitation Radar-2 (APR2), the DC-8 is acting as a simulator for the

Monday, February 6, 2012
Summary will be updated on Fridays through the remainder of the campaign. Latest Update: 2/29/12 Date: February 25 Time: 1600 UTC Event Type: Lake Effect Aircraft: DC-8 Summary: The DC-8 flew home to Dryden Research Flight Center (DRFC) along some points that intersected with light orographic snows in New England and Lake Effect Snows in New York State. The DC-8 intersected snow over the White Mountains near Berlin and Green Mountains south of Rutland before vectoring near Utica, NY, crossing a Lake Effect Snow band southeast of Syracuse, and then traversing just north of a band across the...
