Global Climate Change: Research Explorer - Biosphere
The more visible sunlight a plant absorbs, the more the plant photosynthesizes, using the energy in light to ... of light absorbed by different parts of the earth. When an area absorbs more visible light and less near-infrared light (which is not useful for photosynthesis), researchers know that more vegetation is ...

NOAA/NGDC - Earth Observation Group - Defense Meteorological Satellite Progam, Boulder
OLS visible near-infrared band and the OLS thermal-infrared band. The spatial resolution of the imagery used is 2.7 km. The thermal infrared images show the temperatures of the cloud tops, and ocean and land surfaces, while the visible-near infrared ...

NOAA/NGDC - Earth Observation Group - Defense Meteorological Satellite Progam, Boulder
The DMSP-OLS has a unique capability to detect low levels of visible-near infrared (VNIR) radiance at night. With the OLS "VIS" band data it is possible to detect ... 1994 - March 1995 DMSP nighttime data collected when moonlight was low. Using the OLS thermal infrared band, areas containing clouds were removed and the remaining area used in the time series ...

Data and Satellite Imagery - Data Description
July 1985 to May 1999. The reflectance or turbidity product is derived from the visible channel of the AVHRR and provides a proxy measure of turbidity associated with suspended sediments ... then subtracted from the channel 1 radiance. For an aerosol correction, channel 2 in the near infrared (750-1000 nanometers) is used. It is first corrected for Rayleigh scattering and then subtracted ...

CoastView Volume 2 - Remote Sensing Fundamentals
This reflected radiation is what our eyes use to see objects, causes near-infrared film to record vegetation, and allows radar images of the earth to be created ... vegetation, and severely stressed vegetation. In the visible region on the electromagnetic spectrum, the three spectral signatures look similar. However, in the near-infrared region of the spectrum, the spectral ...

Popular satellite products are created from measurements in the visible and infrared channels of the electromagnetic spectrum. However, the visible channel is restricted to day-time use only. Other usual ... they remain stationary with respect to the Earth's surface. A sunsyncronous satellite typically orbits near the poles in about 850 km height, and circles the Earth in about 100 ...
