The correct answer is option C, which means both statements 1 and 2 are correct.
Explanation:
The Moderate Resolution Imaging Spectroradiometer (MODIS) is indeed a key instrument operating on both the Terra and Aqua satellites. MODIS is a remote sensing instrument designed to capture high-quality images of the Earth's surface and atmosphere. It is one of the primary instruments used for Earth observation by NASA.
MODIS provides data related to global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. It collects data in 36 spectral bands, ranging from visible to thermal infrared wavelengths. These data are used for a wide range of applications, including climate studies, weather forecasting, land cover mapping, and monitoring natural disasters.
The data collected by MODIS is used to study various aspects of the Earth's system, such as vegetation health, sea surface temperature, cloud cover, aerosol distribution, and atmospheric profiles. By observing these parameters, scientists can gain insights into the Earth's climate system, ecosystems, and weather patterns.
MODIS has a spatial resolution of 250 meters to 1 kilometer, depending on the spectral band being used. This allows for detailed observations of the Earth's surface and atmosphere. The instrument also has a high temporal resolution, collecting data on a daily basis.
Both the Terra and Aqua satellites have been in operation since the early 2000s and have provided a wealth of data for scientific research and applications. Terra was launched in 1999, while Aqua was launched in 2002. These satellites are part of NASA's Earth Observing System (EOS) program and have been instrumental in advancing our understanding of the Earth's climate and environment.
In conclusion, the Moderate Resolution Imaging Spectroradiometer (MODIS) is a key instrument operating on both the Terra and Aqua satellites. It provides valuable data related to global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere.

With reference to the Moderate Resolution Imaging Spectroradiometer, c...
Recently, scientists’ have analyzed data generated from the Moderate Resolution Imaging Spectroradiometer and said that climate change has altered the colour of 56 per cent of the world’s oceans.
- It is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites.
- It is a sensor operating on the Terra and Aqua satellites, which were launched by NASA in December 1999 and May 2002.
- Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon.
- Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths.
- These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere.
- Significance: It is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
Hence both statements are correct.
