Correct Option (D)
Satellite images and remote sensing data are extensively used for the measurement and estimation of all three listed parameters:
-
Chlorophyll content in the vegetation of a specific location: Remote sensing techniques utilize the spectral reflectance properties of vegetation. Chlorophyll strongly absorbs red and blue light while reflecting near-infrared light. By analyzing the spectral signatures captured by satellite sensors, variations in chlorophyll concentration can be estimated. This is crucial for assessing plant health, productivity, and stress levels in crops, forests, and other ecosystems.
-
Greenhouse gas emissions from rice paddies of a specific location: Satellite-based remote sensing, often in conjunction with ground observations and atmospheric modeling, can be employed to detect and quantify concentrations of greenhouse gases, such as methane (CH₄), emitted from sources like rice paddies. Specialized sensors are designed to identify the unique spectral absorption features of these gases in the atmosphere, allowing for monitoring of emission hotspots and trends.
-
Land surface temperatures of a specific location: Land Surface Temperature (LST) is a key environmental variable directly measured by thermal infrared sensors onboard satellites. These sensors detect the thermal radiation emitted from the Earth's surface. LST data is vital for a wide range of applications including urban heat island studies, drought monitoring, climate modeling, agricultural management, and understanding energy balance processes.
Incorrect Options
Options 1, 2, and 3 are incorrect because satellite remote sensing is capable of measuring or estimating all three parameters mentioned in statements 1, 2, and 3. Therefore, the option indicating all three statements are correct is the appropriate answer.
