TERRA

Identical sets of devices intended for sensing of the atmosphere and the Earth surface are placed onboard the TERRA and AQUA satellites. A wide range of data on the composition and state of the Earth surface and the atmosphere is generated by the MODIS device. The data of daily sensing of the atmosphere – Earth surface system for the last two weeks are accessible via the corresponding sections of the menu.

Parameters being sensed:

• Optical aerosol thickness.
• Pressure on the upper edge of cloudiness.
• Characteristics of cloudiness (type and phase).
• Precipitated water.
• Vegetation indices (vegetation state).
• Forest fires.
• Earth surface temperature.
• Chlorophyll concentration.
• Earth surface reflection coefficients.
• Profiles of the temperature, humidity and ozone calculated from the MODIS data at 20 points with an altitude step of about 5 km.
