Global Night-Time Lights for Observing Human Activity
We present a concept for a small satellite mission to make systematic, global observations of night-time lights with spatial resolution suitable for discerning the extent, type and density of human settlements. The observations will also allow better understanding of fine scale fossil fuel CO2 emission distribution. The NASA Earth Science Decadal Survey recommends more focus on direct observati...
متن کاملNight Time Vehicle Detection Using Tail Lights: A Survey
The main challenge during night-time driving is the visibility of the road ahead. The major challenge rests in controlling accidents during night as the night conditions differ from the day in environment conditions, vehicle lighting etc. The reduced cost of cameras and optical devices helped in installing front-mounted intelligent systems for identifying forward collision avoidance and mitigat...
متن کاملVIIRS Nightfire: Satellite Pyrometry at Night
The Nightfire algorithm detects and characterizes sub-pixel hot sources using multispectral data collected globally, each night, by the Suomi National Polar Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS). The spectral bands utilized span visible, near-infrared (NIR), short-wave infrared (SWIR), and mid-wave infrared (MWIR). The primary detection band is in the SWIR, centere...
متن کاملThe night the lights went out.
MIT, Harvard, and the surrounding areas lost power from 4:26 to 6:37 p.m. yesterday. The outage threw the Institute into darkness — classes were canceled, MBTA service was delayed, and police were dispatched to direct traffic. Emergency power remained on in dormitories and around campus. The problem is thought to be related to a transmission line in the area, said Michael Durand, NStar spokesma...
متن کاملOcean Dynamics Observed by VIIRS Day/Night Band Satellite Observations
Three cases of Day/Night Band (DNB) observations of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership (SNPP) are explored for applications to assess the ocean environment and monitor ocean dynamics. An approach to use the ratio between the target radiance and the reference radiance was developed in order to better assess the ocean diurna...
