B-roll of a Dual-frequency Dual-polarized Doppler Radar (D3R). The D3R is a fully polarimetric, scanning weather radar system operating at the nominal frequencies of 13.91 GHz and 35.56 GHz covering a maximum range of 30 km. The frequencies chosen allow close compatibility with the GPM Dual-frequency Precipitation Radar system, which was selected for flight on the GPM core spacecraft. This footage was captured during the NASA-led field campaign OLYMPEX.
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. In particular, OLYMPEX will be assessing satellite measurements made by the Global Precipitation Measurement (GPM) mission Core Observatory, a joint mission by NASA and the Japan Aerospace Exploration Agency (JAXA), which launched in 2014.
This is a selection of b-roll that captures the scientists and instruments at work in Washington State.
B-roll of the NASA NPOL radar is a research grade S-band, scanning dual-polarimetric radar. It is used to make accurate volumetric measurements of precipitation including rainfall rate, particle size distributions, water contents and precipitation type. This footage was captured during the NASA-led field campaign OLYMPEX.
