Airborne Wind Lidar measurements of vertical and horizontal winds for the investigation of orographically induced gravity waves
(American Meteorological Society, 2017)irborne coherent Doppler wind lidar measurements, acquired during the GW-LCYCLE I campaign performed from 2 to 14 December 2013 in Kiruna, Sweden, are used to investigate internal gravity waves (GWs) induced by flow across ... -
Spectral dependence of the seawater-air radiance transmission coefficient
(American Meteorological Society, 2017)he transmission coefficient, TL, commonly used to propagate the upwelling nadir radiance, just below the ocean surface, to above the surface has been assumed to be a constant value of 0.543 in seawater. Because the index ... -
A New Radio Frequency Interference Filter for Weather Radars
(American Meteorological Society, 2017)new radio frequency interference (RFI) filter algorithm for weather radars is proposed in the two-dimensional (2D) range-time/sample-time domain. Its operation in 2D space allows RFI detection at lower interference-to-noise ... -

A System for Retrieval and Incubation of Benthic Sediment Cores at In Situ Ambient Pressure and under Controlled or Manipulated Environmental Conditions
(American Meteorological Society, 2017)he investigation of benthic biodiversity and biogeochemical processes in the deep sea is complicated by the need to conduct experiments at in situ pressures. Recovery of sediment samples to the surface without maintaining ... -
Significant Improvements in Pyranometer Nighttime Offsets Using High-Flow, DC Ventilation
(American Meteorological Society, 2017)entilators are used to keep the domes of pyranometers clean and dry, but they affect the nighttime offset as well. This paper examines different ventilation strategies. For the several commercial single-black-detector ... -
A method to extrapolate the diffuse upwelling radiance attenuation coefficient to the surface as applied to the Marine Optical Buoy (MOBY)
(American Meteorological Society, 2017)he upwelling radiance attenuation coefficient (KLu) in the upper 10 m of the water column can be significantly influenced by inelastic scattering processes, and thus will vary even with homogeneous water properties. The ... -
