Paper on the Doppler Wind Lidar, a new instrument to measure wind from hurricane hunter aircraft, published in the journal Sensors

Summary: A new instrument, called an airborne Doppler Wind Lidar (ADWL, for short), was flown on NOAA’s hurricane hunter aircraft into two storms during 2016. This instrument measures winds above and below the plane. The ADWL measures wind where radar on the aircraft cannot: the radar can measure the wind where there are clouds or … Continue reading Paper on the Doppler Wind Lidar, a new instrument to measure wind from hurricane hunter aircraft, published in the journal Sensors

Paper on measuring surface wind speed from hurricane hunter aircraft when it turns and rolls published in the Journal of Atmospheric and Oceanic Technology

Summary: The Stepped-Frequency Microwave Radiometer (SFMR) is an instrument flown on the NOAA and Air Force Hurricane Hunter aircraft that measures surface wind speed and how much rain is falling over the ocean in tropical cyclones.  Historically, the SFMR measurements have only been used when the aircraft is not turning or going up or down … Continue reading Paper on measuring surface wind speed from hurricane hunter aircraft when it turns and rolls published in the Journal of Atmospheric and Oceanic Technology
