Global Climate Change: Research Explorer - Biosphere
The more visible sunlight a plant absorbs, the more the plant photosynthesizes, using the energy in light to produce ... 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
The 14 most intense tropical storms from the 1996 calendar year are shown with thermal infrared imagery from the DMSP Operational Linescan System. Although 1998 produced fewer tropical storms than the ...

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 ... the October 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. There ...

ESB: Choose Glazing by the Numbers
"Sunlight" falling on a window is made up of visible light, near infrared energy (heat) and ultraviolet light. This energy is either absorbed by the glass, ... UV transmission under 1 percent. However, about 20 percent of sunlight's fading power comes from visible light. So even completely blocking UV doesn't stop fading altogether. Mechanical Savings Since glazing ...

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. It ... and 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 ...

CoastView Volume 2 - Remote Sensing Fundamentals
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 signatures ... be used for night vision instruments. The peak emission wavelength for a human is in the infrared at 9.4 micrometers, while an object at 15.5 Celsius (60 F) would have ...

FMI - Weather and Climate - Rain and cloudiness - Info on satellites
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 minutes ...

Gentex Corporation - Fuel Cell Today
Clearweld is the preferred joining technology for the cell components to produce hermetically sealed channels with no distortion. Clearweld, uses high-density, near-infrared (NIR) energy that passes through an IR transmissive substrate to an IR-absorbing interface to provide the following advantages. • A strong, hermetic seal.• Low mechanical and ...

Evapotranspiration | ESA_WAT
Soil moisture in the root zone SEBAL is essentially applied with NASA-borne satellites measuring reflectance in the visible, near infrared and thermal infrared parts of the spectrum (e.g. Landsat, MODIS,). These data are obtained for each individual satellite image that is available for an area. By combining several individual images into a time series, one ...
