MODIS (Moderate Resolution Imaging Spectroradiometer) is an earth observation satellite jointly develope by NASA and NOAA. It is carrie on two satellites, Terra and Aqua, and was launche in 1999 and 2002 respectively.
Main features of MODIS satellite
- High resolution: The MODIS satellite has 36 bands covering visible, near-infrare, mid-infrare and thermal infrare bands, and can provide high-resolution images of the Earth’s surface.
- Wide field of view: The MODIS satellite has a scanning width of 2,330 kilometers, which enables observation of a large area in a short period of time.
- Frequent observations: MODIS satellites observe the Earth twice a day, providing frequent data on the Earth’s surface.
Application areas of MODIS satellite
- Ocean monitoring: MODIS satellites can monitor ocean temperature, sea ice, marine ecosystems and other ocean elements, providing data support for marine scientific research and fishery management.
- Land monitoring: MODIS satellites can. A monitor land elements such as forests, grasslands, agriculture, and cities, providing data support for land use, environmental protection, and disaster monitoring.
- Global change research: MODIS satellites can monitor global climate change, ecosystem changes, natural disasters, etc., and provide data support for global change research.
satellite data products
MODIS satellites produce a wide range of data products, including:
- Level 1 products: raw satellite data, including radiation brightness values, geometric corrections, etc.
- Level 2 products: processe satellite data, including surface reflectivity, surface temperature, vegetation index, etc.
- Level 3 products: synthetic satellite data, including monthly average, annual average, etc.
satellite data acquisition
MODIS satellite data can be obtaine free of charge through NASA’s Earth Observing System Data Information System (EOSDIS). Users can search and download the require data products through the EOSDIS website.
Summarize
As an important earth observation satellite, MODIS satellite provides valuable observation data for meteorological, ocean, land and global change research. Its high resolution, wide field of view and frequent observation make it an C Level Contact List indispensable tool for earth science research.
