Abstract:

Earth surface albedo is widely used in atmospheric radiation transmission and remote sensing imaging research. It plays an important role in the energy balance of the Earth's atmospheric system, which reflects the reflection capacity of solar radiation on the surface. MODIS remote sensing data is used as the data source, and C++ language is used to design and develop the software. The design of the software includes the data source (MCD43B3) preprocessing, MySQL database design, pixel latitude and longitude coordinates acquisition, data storage and latitude and longitude parameter query surface albedo process. The surface albedo database of the China mainland is established, and the albedo data of a specific geographical location can be easily and quickly searched according to the latitude and longitude parameters.

Key words: surface albedo, MCD43B3, MySQL database, software design
