This question requires matching specific Earth observation satellite platforms with their associated sensors. Let's analyze each platform:
The Aqua satellite, launched by NASA, is part of the Earth Observing System (EOS). It carries multiple instruments, including the Moderate Resolution Imaging Spectroradiometer (MODIS). Therefore, Aqua is correctly matched with MODIS.
Match: A - II (MODIS)
NOAA (National Oceanic and Atmospheric Administration) operates numerous weather and environmental satellites. Key sensors found on NOAA platforms include the Visible Infrared Imaging Radiometer Suite (VIIRS) and the Advanced Very High Resolution Radiometer (AVHRR), which are crucial for weather monitoring and climate studies.
Match: B - IV (VIIRS, AVHRR)
The Sentinel-2 mission, part of the European Space Agency's Copernicus Programme, focuses on providing high-resolution optical imagery for land monitoring, emergency management, and security applications. Its primary instrument is the Multispectral Instrument (MSI).
Match: C - I (MSI)
The Terra satellite, also launched by NASA as part of the Earth Observing System, carries a suite of instruments designed to study the interactions between the atmosphere, oceans, land, and solar radiation. Notable sensors aboard Terra include ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) and MODIS.
Match: D - III (ASTER, MODIS)
The correct pairings between the satellite platforms (LIST-I) and their sensors (LIST-II) are as follows:
| Platform (LIST-I) | Sensors (LIST-II) |
|---|---|
| A. Aqua | II. MODIS |
| B. NOAA | IV. VIIRS, AVHRR |
| C. Sentinel - 2 | I. MSI |
| D. Terra | III. ASTER, MODIS |
Based on this analysis, the correct option is A-II, B-IV, C-I, D-III.
| List-I (Types of resolution) | List-II (Description) |
| A. Spatial Resolution | I. Number of independent channels |
| B. Temporal Resolution | II. Sensitivity of the detectors |
| C. Spectral Resolution | III. Frequency of measurement |
| D. Radiometric Resolution | IV. Smaller spatial measurement |
