Piasecki Aircraft (PiAC) proposes to continue development and testing efforts of the Whimbrel UAS, a low cost, expendable, air-deployed weather survey unmanned aircraft system. The Whimbrel UAS, a low cost, expendable, air-deployed weather survey unmanned aircraft system. The Whimbrel USA has been developed to support the Tropical Cyclone Boundary Layer mission requirements and contains sensors an ...

A new radiometric vicarious calibration approach for the Suomi NPP VIIRS Day/Night Band’s (DNB) high gain stage (HGS) is proposed that will complement traditional, extended source, radiance-based calibrations, which are based on natural lunar illumination and not as accurate as desired. The proposed research will produce affordable, field-deployable, NIST-traceable point source lamps that can ac ...

The value of the subseasonal and seasonal probability forecasts of the National Weather Service (NWS) will be enhanced when the information about standard meteorological variables is converted into information about business impact variables such as degree days, wind and solar power potential, and end-of-season crop yield. Toward that goal, in Phase I we will identify a suite of such action variab ...

To capture critical weather and SST data in the Tropical Cyclone Boundary Layer (TCBL), Piasecki Aircraft proposes to evaluate existing meteorological sensor packages, integrate new off-the-shelf MEMS sensors, and design an air-launched UAS to improve the resolution of observations captured in the TCBL. Capturing latent and sensible heat fluxes can be achieved reliably with a powered UAS (compare ...

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...
