Snow and ice products from Suomi NPP VIIRS [PDF]

Journal of Geophysical Research: Atmospheres, 2013
AbstractThe Visible Infrared Imager Radiometer Suite (VIIRS) instrument was launched in October 2011 on the satellite now known as the Suomi National Polar‐orbiting Partnership. VIIRS was designed to improve upon the capabilities of the operational Advanced Very High Resolution Radiometer and provide observation continuity with NASA's Earth Observing ...

Radiometric Inter-Consistency of VIIRS DNB on Suomi NPP and NOAA-20 from Observations of Reflected Lunar Lights over Deep Convective Clouds

Remote Sensing, 2019
The Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) is capable of observing reflected lunar radiances at night with its high gain stage (HGS), and the radiometric calibration is traceable to the sun through gain transfer from the ...

Adapting to Urban Heights: Multidimensional Gradients Drive Nest‐Selection Plasticity and Trade‐Offs in a Human‐Commensal Sparrow

Integrative Zoology, EarlyView.
Urban Eurasian tree sparrows exhibit pronounced nest‐site plasticity, exploiting vertical building space while preferring lower nest heights when sites are abundant. Nest decisions are driven by altitude and building height rather than other factors, indicating a shift toward anthropogenic resources in cities.

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

Ibis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...
