Question

For the measurement/ estimation of which of the following are satellite images/remote sensing data used?Chlorophyll content in the vegetation of a specific locationGreenhouse gas emissions from rice paddies of a specific locationLand surface temperatures of a specific locationSelect the correct answer using the code given below.

Accepted Answer

With the development of remote sensing from space, satellite data offers the possibility for measuring land surface temperature over the entire globe with sufficiently high temporal resolution and with complete spatially averaged rather than point values.The global food supply is being monitored with satellite imagery and the Normalized Difference Vegetation Index (NDVI). Near-infrared radiation is being used to detect healthy vegetation in agriculture. Healthy vegetation reflects green light and absorbs red and blue light. The green light that our eyes see is chlorophyll created by plants during photosynthesis. Chlorophyll will reflect more light in the green and near infrared spectrum compared to other wavelengths. This is why near infrared radiation in combination with NDVI is one of the primary remote sensing applications in agriculture and the environment.Remote sensing from satellites can deliver information on GHG soil emissions by estimating tropospherical, near-surface CO2 and CH4 concentrations based on the measurement of the intensity of the reflected sunlight in small wavelength bands in the visible and short-wavelength IR portion of the spectrum.
